## Optiboot Bootloader for Arduino and Atmel AVR ##
![docs/optiboot.png](docs/optiboot.png)
Optiboot is an easy to install upgrade to the Arduino bootloader within Arduino boards. It provides the following features:
* Allows larger sketches. Optiboot is a quarter of the size of the default bootloader, freeing 1.5k of extra space.
* Makes your sketches upload faster. Optiboot operates at higher baud rates and has streamlined programming.
* Adaboot performance improvements. Optiboot runs your sketches sooner, with no watchdog issues.
* Compatible with 168 and 328 Arduinos including Lilypad, Pro, Nano
* Believed to work with ATmega1280 ("Mega"), ATmega644 ("Sanguino"), and ATmega1284 ("Mighty")
* Supports several additional AVR chips (ATmega88, ATmega32)
Optiboot is now installed by default on the Arduino Uno. It can be installed on all older mega8, 168 or 328 based Arduinos.
## Additional Documentation
More detailed documentation is being added (slowly) to the [repository wiki](https://github.com/Optiboot/optiboot/wiki).
## Notes on IDE Version compatability
Optiboot is "compatible", in a loose sense, with all versions of the Arduino IDE. It was originally written at about the same time as v1.0, and has some "quirks" that date back to that timeframe. Most significantly, install procedures and locations change between releases, and the ability to compile Optiboot using only the tools installed with the IDE broke in the v1.5 timeframe.
## To install into the Arduino software ##
You do NOT need to "install" Optiboot if you are trying to update an installed platform that already uses some form of Optiboot. In that case, you should probably just find and replace the existing .hex files from the platform support directories. Using the Optiboot "install" procedure does not install any cores or variants, so it is only useful for CPUs that are already supported by the standard Arduino core (or, if all you want to do is install bootloaders.)
The following instructions are based on using the Arduino "Board Manager", present in IDE versions 1.6.5 and later.
1. Find the desired Optiboot release on the [Optiboot Release page] (https://github.com/Optiboot/optiboot/releases).
2. Use the "Copy link address" feature of your browser to copy the URL of the associated **.json** file.
3. Paste this url into the "Additional Boards Manager URLs" field in the Arduino IDE "Preferences" pane. (Separate it from other URLs that might be present with a comma or click the icon to the right of the field to insert it on a new line.)
4. After closing the Preferences window, the **Tools/Boards/Boards Manager** menu should include an entry for that version of Optiboot. Select that entry and click the **Install** button.
For additional installation information, see the [Optiboot AddingOptibootChipsToIde Wiki page] (https://github.com/Optiboot/optiboot/wiki/AddingOptibootChipsToIde)
<!---
1. Download the latest using Git or the Zip download feature of GitHub. If you download as a zip, also extract it.
1. You will need to be using a recent version of the [Arduino environment](http://arduino.cc), version 18 or later.
1. Create a 'hardware' directory inside your sketches folder.
1. Copy the optiboot directory into the hardware directory.
1. Restart the Arduino software. New boards will appear in the Tools>Board menu.
--->
## To burn Optiboot onto an Arduino board ##
1. Select the appropriate Optiboot board type (or non-Optiboot if you want to change back)
1. Connect your Arduino to an ISP programmer [[Installing]]
1. Use the 'Burn Bootloader' item in Arduino.
1. You can then upload sketches as normal, using the Optiboot board type.
----
> Although it has evolved considerably, Optiboot builds on the original work of Jason P. Kyle (stk500boot.c), [Arduino group (bootloader)](http://arduino.cc), [Spiff (1K bootloader)](http://spiffie.org/know/arduino_1k_bootloader/bootloader.shtml), [AVR-Libc group](http://nongnu.org/avr-libc) and [Ladyada (Adaboot)](http://www.ladyada.net/library/arduino/bootloader.html).
> _Optiboot is the work of Peter Knight (aka Cathedrow). Despite some misattributions, it is not sponsored or supported by any organisation or company including Tinker London, Tinker.it! and Arduino._
> Maintenance of optiboot was taken over by Bill Westfield (aka WestfW) in 2011.

# Makefile for ATmegaBOOT
# E.Lins, 18.7.2005
# $Id$
#
# Instructions
#
# To make bootloader .hex file:
# make diecimila
# make lilypad
# make ng
# etc...
#
# To burn bootloader .hex file:
# make diecimila_isp
# make lilypad_isp
# make ng_isp
# etc...
#
# Edit History
# 201406xx: WestfW: More Makefile restructuring.
# Split off Makefile.1284, Makefile.extras, Makefile.custom
# So that in theory, the main Makefile contains only the
# official platforms, and does not need to be modified to
# add "less supported" chips and boards.
# 201303xx: WestfW: Major Makefile restructuring.
# Allows options on Make command line "make xx LED=B3"
# (see also pin_defs.h)
# Divide into "chip" targets and "board" targets.
# Most boards are (recursive) board targets with options.
# Move isp target to separate makefile (fixes m8 EFUSE)
# Some (many) targets will now be rebuilt when not
# strictly necessary, so that options will be included.
# (any "make" with options will always compile.)
# Set many variables with ?= so they can be overridden
# Use arduinoISP settings as default for ISP targets

# "Chip-level Platform" targets.
# A "Chip-level Platform" compiles for a particular chip, but probably does
# not have "standard" values for things like clock speed, LED pin, etc.
# Makes for chip-level platforms should usually explicitly define their
# options like: "make atmega1285 AVR_FREQ=16000000L LED=D0"
#---------------------------------------------------------------------------
#
# Note about fuses:
# the efuse should really be 0xf8; since, however, only the lower
# three bits of that byte are used on the atmega168, avrdude gets
# confused if you specify 1's for the higher bits, see:
# http://tinker.it/now/2007/02/24/the-tale-of-avrdude-atmega168-and-extended-bits-fuses/
#
# similarly, the lock bits should be 0xff instead of 0x3f (to
# unlock the bootloader section) and 0xcf instead of 0x2f (to
# lock it), but since the high two bits of the lock byte are
# unused, avrdude would get confused.

This directory contains the Optiboot small bootloader for AVR
microcontrollers, somewhat modified specifically for the Arduino
environment.
Optiboot is more fully described here: http://github.com/Optiboot/optiboot
and is the work of Peter Knight (aka Cathedrow), building on work of Jason P
Kyle, Spiff, and Ladyada. More recent maintenance and modifications are by
Bill Westfield (aka WestfW)
Arduino-specific issues are tracked as part of the Arduino project
at http://github.com/arduino/Arduino
Most of the information in this file is superceeded by the wiki content at
https://github.com/Optiboot/optiboot/wiki
It's till here "just in case."
------------------------------------------------------------
Building optiboot for Arduino.
Production builds of optiboot for Arduino are done on a Mac in "unix mode"
using CrossPack-AVR-20100115. CrossPack tracks WINAVR (for windows), which
is just a package of avr-gcc and related utilities, so similar builds should
work on Windows or Linux systems.
One of the Arduino-specific changes is modifications to the makefile to
allow building optiboot using only the tools installed as part of the
Arduino environment, or the Arduino source development tree. All three
build procedures should yield identical binaries (.hex files) (although
this may change if compiler versions drift apart between CrossPack and
the Arduino IDE.)
Building Optiboot in the Arduino IDE Install.
Work in the .../hardware/arduino/bootloaders/optiboot/ and use the
"omake <targets>" command, which just generates a command that uses
the arduino-included "make" utility with a command like:
make OS=windows ENV=arduino <targets>
or make OS=macosx ENV=arduino <targets>
On windows, this assumes you're using the windows command shell. If
you're using a cygwin or mingw shell, or have one of those in your
path, the build will probably break due to slash vs backslash issues.
On a Mac, if you have the developer tools installed, you can use the
Apple-supplied version of make.
The makefile uses relative paths ("../../../tools/" and such) to find
the programs it needs, so you need to work in the existing optiboot
directory (or something created at the same "level") for it to work.
Building Optiboot in the Arduino Source Development Install.
In this case, there is no special shell script, and you're assumed to
have "make" installed somewhere in your path.
Build the Arduino source ("ant build") to unpack the tools into the
expected directory.
Work in Arduino/hardware/arduino/bootloaders/optiboot and use
make OS=windows ENV=arduinodev <targets>
or make OS=macosx ENV=arduinodev <targets>
Programming Chips Using the _isp Targets
The CPU targets have corresponding ISP targets that will actuall
program the bootloader into a chip. "atmega328_isp" for the atmega328,
for example. These will set the fuses and lock bits as appropriate as
well as uploading the bootloader code.
ISP Targets in Version 5.0 and later:
The isp targets are now built using a separate "Makefile.isp" makefile,
which should make modification easier and more obvious. This also fixes
the atmega8_isp target problem mentioned below. The default
configuration assumes an ArduinoISP setup, but you will probably need to
update at least the serial port, since those are different for each
Arduino board and/or system/
ISP Targets in Version 4.6 and earlier:
The older makefiles default to using a USB programmer, but you can use a
serial programmer like ArduinoISP by changing the appropriate variables
when you invoke make:
make ISPTOOL=stk500v1 ISPPORT=/dev/tty.usbserial-A20e1eAN \
ISPSPEED=-b19200 atmega328_isp
The "atmega8_isp" target does not currently work, because the mega8
doesn't have the "extended" fuse that the generic ISP target wants to
pass on to avrdude. You'll need to run avrdude manually.
Standard Targets
I've reduced the pre-built and source-version-controlled targets
(.hex and .lst files included in the git repository) to just the
three basic 16MHz targets: atmega8, atmega16, atmega328.

"\n"
"\n"
"WHILOM*, as olde stories tellen us, *formerly\n"
"There was a duke that highte* Theseus. *was called <2>\n"
"Of Athens he was lord and governor,\n"
"And in his time such a conqueror\n"
"That greater was there none under the sun.\n"
"Full many a riche country had he won.\n"
"What with his wisdom and his chivalry,\n"
"He conquer'd all the regne of Feminie,<3>\n"
"That whilom was y-cleped Scythia;\n"
"And weddede the Queen Hippolyta\n"
"And brought her home with him to his country\n"
"With muchel* glory and great solemnity, *great\n"
"And eke her younge sister Emily,\n"
"And thus with vict'ry and with melody\n"
"Let I this worthy Duke to Athens ride,\n"
"And all his host, in armes him beside.\n"
"\n"
"And certes, if it n'ere* too long to hear, *were not\n"
"I would have told you fully the mannere,\n"
"How wonnen* was the regne of Feminie, <4> *won\n"
"By Theseus, and by his chivalry;\n"
"And of the greate battle for the nonce\n"
"Betwixt Athenes and the Amazons;\n"
"And how assieged was Hippolyta,\n"
"The faire hardy queen of Scythia;\n"
"And of the feast that was at her wedding\n"
"And of the tempest at her homecoming.\n"
"But all these things I must as now forbear.\n"
"I have, God wot, a large field to ear* *plough<5>;\n"
"And weake be the oxen in my plough;\n"
"The remnant of my tale is long enow.\n"
"I will not *letten eke none of this rout*. *hinder any of\n"
"Let every fellow tell his tale about, this company*\n"
"And let see now who shall the supper win.\n"
"There *as I left*, I will again begin. *where I left off*\n"
"\n"
"This Duke, of whom I make mentioun,\n"
"When he was come almost unto the town,\n"
"In all his weal, and in his moste pride,\n"
"He was ware, as he cast his eye aside,\n"
"Where that there kneeled in the highe way\n"
"A company of ladies, tway and tway,\n"
"Each after other, clad in clothes black:\n"
"But such a cry and such a woe they make,\n"
"That in this world n'is creature living,\n"
"That hearde such another waimenting* *lamenting <6>\n"
"And of this crying would they never stenten*, *desist\n"
"Till they the reines of his bridle henten*. *seize\n"
"\"What folk be ye that at mine homecoming\n"
"Perturben so my feaste with crying?\"\n"
"Quoth Theseus; \"Have ye so great envy\n"
"Of mine honour, that thus complain and cry?\n"
"Or who hath you misboden*, or offended? *wronged\n"
"Do telle me, if it may be amended;\n"
"And why that ye be clad thus all in black?\"\n"
"\n"
"The oldest lady of them all then spake,\n"
"When she had swooned, with a deadly cheer*, *countenance\n"
"That it was ruthe* for to see or hear. *pity\n"
"She saide; \"Lord, to whom fortune hath given\n"
"Vict'ry, and as a conqueror to liven,\n"
"Nought grieveth us your glory and your honour;\n"
"But we beseechen mercy and succour.\n"
"Have mercy on our woe and our distress;\n"
"Some drop of pity, through thy gentleness,\n"
"Upon us wretched women let now fall.\n"
"For certes, lord, there is none of us all\n"
"That hath not been a duchess or a queen;\n"
"Now be we caitives*, as it is well seen: *captives\n"
"Thanked be Fortune, and her false wheel,\n"
"That *none estate ensureth to be wele*. *assures no continuance of\n"
"And certes, lord, t'abiden your presence prosperous estate*\n"
"Here in this temple of the goddess Clemence\n"
"We have been waiting all this fortenight:\n"
"Now help us, lord, since it lies in thy might.\n"

"Was whilom wife to king Capaneus,\n"
"That starf* at Thebes, cursed be that day: *died <7>\n"
"And alle we that be in this array,\n"
"And maken all this lamentatioun,\n"
"We losten all our husbands at that town,\n"
"While that the siege thereabouten lay.\n"
"And yet the olde Creon, wellaway!\n"
"That lord is now of Thebes the city,\n"
"Fulfilled of ire and of iniquity,\n"
"He for despite, and for his tyranny,\n"
"To do the deade bodies villainy*, *insult\n"
"Of all our lorde's, which that been y-slaw, *slain\n"
"Hath all the bodies on an heap y-draw,\n"
"And will not suffer them by none assent\n"
"Neither to be y-buried, nor y-brent*, *burnt\n"
"But maketh houndes eat them in despite.\"\n"
"And with that word, withoute more respite\n"
"They fallen groff,* and cryden piteously; *grovelling\n"
"\"Have on us wretched women some mercy,\n"
"And let our sorrow sinken in thine heart.\"\n"
"\n"
"This gentle Duke down from his courser start\n"
"With hearte piteous, when he heard them speak.\n"
"Him thoughte that his heart would all to-break,\n"
"When he saw them so piteous and so mate* *abased\n"
"That whilom weren of so great estate.\n"
"And in his armes he them all up hent*, *raised, took\n"
"And them comforted in full good intent,\n"
"And swore his oath, as he was true knight,\n"
"He woulde do *so farforthly his might* *as far as his power went*\n"
"Upon the tyrant Creon them to wreak*, *avenge\n"
"That all the people of Greece shoulde speak,\n"
"How Creon was of Theseus y-served,\n"
"As he that had his death full well deserved.\n"
"And right anon withoute more abode* *delay\n"
"His banner he display'd, and forth he rode\n"
"To Thebes-ward, and all his, host beside:\n"
"No ner* Athenes would he go nor ride, *nearer\n"
"Nor take his ease fully half a day,\n"
"But onward on his way that night he lay:\n"
"And sent anon Hippolyta the queen,\n"
"And Emily her younge sister sheen* *bright, lovely\n"
"Unto the town of Athens for to dwell:\n"
"And forth he rit*; there is no more to tell. *rode\n"
"\n"
"The red statue of Mars with spear and targe* *shield\n"
"So shineth in his white banner large\n"
"That all the fieldes glitter up and down:\n"
"And by his banner borne is his pennon\n"
"Of gold full rich, in which there was y-beat* *stamped\n"
"The Minotaur<8> which that he slew in Crete\n"
"Thus rit this Duke, thus rit this conqueror\n"
"And in his host of chivalry the flower,\n"
"Till that he came to Thebes, and alight\n"
"Fair in a field, there as he thought to fight.\n"
"But shortly for to speaken of this thing,\n"
"With Creon, which that was of Thebes king,\n"
"He fought, and slew him manly as a knight\n"
"In plain bataille, and put his folk to flight:\n"
"And by assault he won the city after,\n"
"And rent adown both wall, and spar, and rafter;\n"
"And to the ladies he restored again\n"
"The bodies of their husbands that were slain,\n"
"To do obsequies, as was then the guise*. *custom\n"
"\n"
"But it were all too long for to devise* *describe\n"
"The greate clamour, and the waimenting*, *lamenting\n"
"Which that the ladies made at the brenning* *burning\n"
"Of the bodies, and the great honour\n"
"That Theseus the noble conqueror\n"
"Did to the ladies, when they from him went:\n"
"But shortly for to tell is mine intent.\n"
"When that this worthy Duke, this Theseus,\n"
"Had Creon slain, and wonnen Thebes thus,\n"
"Still in the field he took all night his rest,\n"
"And did with all the country as him lest*. *pleased\n"
"To ransack in the tas* of bodies dead, *heap\n"
"Them for to strip of *harness and of **weed, *armour **clothes\n"
"The pillers* did their business and cure, *pillagers <9>\n"
"After the battle and discomfiture.\n"
"And so befell, that in the tas they found,\n"
"Through girt with many a grievous bloody wound,\n"
"Two younge knightes *ligging by and by* *lying side by side*\n"
"Both in *one armes*, wrought full richely: *the same armour*\n"
"Of whiche two, Arcita hight that one,\n"
"And he that other highte Palamon.\n"
"Not fully quick*, nor fully dead they were, *alive\n"
"But by their coat-armour, and by their gear,\n"
"The heralds knew them well in special,\n"
"As those that weren of the blood royal\n"
"Of Thebes, and *of sistren two y-born*. *born of two sisters*\n"
"Out of the tas the pillers have them torn,\n"
"And have them carried soft unto the tent\n"
"Of Theseus, and he full soon them sent\n"
"To Athens, for to dwellen in prison\n"
"Perpetually, he *n'olde no ranson*. *would take no ransom*\n"
"And when this worthy Duke had thus y-done,\n"
"He took his host, and home he rit anon\n"
"With laurel crowned as a conquerour;\n"
"And there he lived in joy and in honour\n"
"Term of his life; what needeth wordes mo'?\n"
"And in a tower, in anguish and in woe,\n"
"Dwellen this Palamon, and eke Arcite,\n"
"For evermore, there may no gold them quite* *set free\n"
"\n"
"Thus passed year by year, and day by day,\n"
"Till it fell ones in a morn of May\n"
"That Emily, that fairer was to seen\n"
"Than is the lily upon his stalke green,\n"
"And fresher than the May with flowers new\n"
"(For with the rose colour strove her hue;\n"
"I n'ot* which was the finer of them two), *know not\n"
"Ere it was day, as she was wont to do,\n"
"She was arisen, and all ready dight*, *dressed\n"
"For May will have no sluggardy a-night;\n"
"The season pricketh every gentle heart,\n"
"And maketh him out of his sleep to start,\n"
"And saith, \"Arise, and do thine observance.\"\n"
"\n"
"This maketh Emily have remembrance\n"
"To do honour to May, and for to rise.\n"
"Y-clothed was she fresh for to devise;\n"
"Her yellow hair was braided in a tress,\n"
"Behind her back, a yarde long I guess.\n"
"And in the garden at *the sun uprist* *sunrise\n"
"She walketh up and down where as her list.\n"
"She gathereth flowers, party* white and red, *mingled\n"
"To make a sotel* garland for her head, *subtle, well-arranged\n"
"And as an angel heavenly she sung.\n"
"The greate tower, that was so thick and strong,\n"
"Which of the castle was the chief dungeon<10>\n"
"(Where as these knightes weren in prison,\n"
"Of which I tolde you, and telle shall),\n"
"Was even joinant* to the garden wall, *adjoining\n"
"There as this Emily had her playing.\n"
"\n"
"Bright was the sun, and clear that morrowning,\n"
"And Palamon, this woful prisoner,\n"
"As was his wont, by leave of his gaoler,\n"
"Was ris'n, and roamed in a chamber on high,\n"
"In which he all the noble city sigh*, *saw\n"
"And eke the garden, full of branches green,\n"
"There as this fresh Emelia the sheen\n"
"Was in her walk, and roamed up and down.\n"
"This sorrowful prisoner, this Palamon\n"
"Went in his chamber roaming to and fro,\n"
"And to himself complaining of his woe:\n"
"That he was born, full oft he said, Alas!\n"
"And so befell, by aventure or cas*, *chance\n"
"That through a window thick of many a bar\n"
"Of iron great, and square as any spar,\n"
"He cast his eyes upon Emelia,\n"
"And therewithal he blent* and cried, Ah! *started aside\n"
"As though he stungen were unto the heart.\n"
"And with that cry Arcite anon up start,\n"
"And saide, \"Cousin mine, what aileth thee,\n"
"That art so pale and deadly for to see?\n"
"Why cried'st thou? who hath thee done offence?\n"
"For Godde's love, take all in patience\n"
"Our prison*, for it may none other be. *imprisonment\n"
"Fortune hath giv'n us this adversity'.\n"
"Some wick'* aspect or disposition *wicked\n"
"Of Saturn<11>, by some constellation,\n"
"Hath giv'n us this, although we had it sworn,\n"
"So stood the heaven when that we were born,\n"
"We must endure; this is the short and plain.\n"
"\n"
"This Palamon answer'd, and said again:\n"
"\"Cousin, forsooth of this opinion\n"
"Thou hast a vain imagination.\n"
"This prison caused me not for to cry;\n"
"But I was hurt right now thorough mine eye\n"
"Into mine heart; that will my bane* be. *destruction\n"
"The fairness of the lady that I see\n"
"Yond in the garden roaming to and fro,\n"
"Is cause of all my crying and my woe.\n"
"I *n'ot wher* she be woman or goddess, *know not whether*\n"
"But Venus is it, soothly* as I guess, *truly\n"
"And therewithal on knees adown he fill,\n"
"And saide: \"Venus, if it be your will\n"
"You in this garden thus to transfigure\n"
"Before me sorrowful wretched creature,\n"
"Out of this prison help that we may scape.\n"
"And if so be our destiny be shape\n"
"By etern word to dien in prison,\n"
"Of our lineage have some compassion,\n"
"That is so low y-brought by tyranny.\"\n"
"\n"
"And with that word Arcita *gan espy* *began to look forth*\n"
"Where as this lady roamed to and fro\n"
"And with that sight her beauty hurt him so,\n"
"That if that Palamon was wounded sore,\n"
"Arcite is hurt as much as he, or more.\n"
"And with a sigh he saide piteously:\n"
"\"The freshe beauty slay'th me suddenly\n"
"Of her that roameth yonder in the place.\n"
"And but* I have her mercy and her grace, *unless\n"
"That I may see her at the leaste way,\n"
"I am but dead; there is no more to say.\"\n"
"This Palamon, when he these wordes heard,\n"
"Dispiteously* he looked, and answer'd: *angrily\n"
"\"Whether say'st thou this in earnest or in play?\"\n"
"\"Nay,\" quoth Arcite, \"in earnest, by my fay*. *faith\n"
"God help me so, *me lust full ill to play*.\" *I am in no humour\n"
"This Palamon gan knit his browes tway. for jesting*\n"

"And right anon withoute more abode* *delay\n"
"His banner he display'd, and forth he rode\n"
"To Thebes-ward, and all his, host beside:\n"
"No ner* Athenes would he go nor ride, *nearer\n"
"Nor take his ease fully half a day,\n"
"But onward on his way that night he lay:\n"
"And sent anon Hippolyta the queen,\n"
"And Emily her younge sister sheen* *bright, lovely\n"
"Unto the town of Athens for to dwell:\n"

"The red statue of Mars with spear and targe* *shield\n"

"But shortly for to speaken of this thing,\n"
"With Creon, which that was of Thebes king,\n"
"He fought, and slew him manly as a knight\n"
"In plain bataille, and put his folk to flight:\n"
"And by assault he won the city after,\n"
"And rent adown both wall, and spar, and rafter;\n"
"And to the ladies he restored again\n"
"The bodies of their husbands that were slain,\n"
"To do obsequies, as was then the guise*. *custom\n"

"But it were all too long for to devise* *describe\n"

"Of the bodies, and the great honour\n"
"That Theseus the noble conqueror\n"
"Did to the ladies, when they from him went:\n"
"But shortly for to tell is mine intent.\n"
"When that this worthy Duke, this Theseus,\n"

"To ransack in the tas* of bodies dead, *heap\n"
"Them for to strip of *harness and of **weed, *armour **clothes\n"
"The pillers* did their business and cure, *pillagers <9>\n"
"After the battle and discomfiture.\n"
"And so befell, that in the tas they found,\n"
"Through girt with many a grievous bloody wound,\n"
"Two younge knightes *ligging by and by* *lying side by side*\n"
"Both in *one armes*, wrought full richely: *the same armour*\n"
"Of whiche two, Arcita hight that one,\n"

"Not fully quick*, nor fully dead they were, *alive\n"
"But by their coat-armour, and by their gear,\n"
"The heralds knew them well in special,\n"
"As those that weren of the blood royal\n"
"Of Thebes, and *of sistren two y-born*. *born of two sisters*\n"
"Out of the tas the pillers have them torn,\n"
"And have them carried soft unto the tent\n"
"Of Theseus, and he full soon them sent\n"
"To Athens, for to dwellen in prison\n"
"Perpetually, he *n'olde no ranson*. *would take no ransom*\n"
"And when this worthy Duke had thus y-done,\n"
"He took his host, and home he rit anon\n"
"With laurel crowned as a conquerour;\n"
"And there he lived in joy and in honour\n"
"Term of his life; what needeth wordes mo'?\n"
"And in a tower, in anguish and in woe,\n"

"For evermore, there may no gold them quite* *set free\n"

"Thus passed year by year, and day by day,\n"
"Till it fell ones in a morn of May\n"
"That Emily, that fairer was to seen\n"
"Than is the lily upon his stalke green,\n"
"And fresher than the May with flowers new\n"
"(For with the rose colour strove her hue;\n"
"I n'ot* which was the finer of them two), *know not\n"
"Ere it was day, as she was wont to do,\n"
"She was arisen, and all ready dight*, *dressed\n"
"For May will have no sluggardy a-night;\n"
"The season pricketh every gentle heart,\n"

"This maketh Emily have remembrance\n"
"To do honour to May, and for to rise.\n"
"Y-clothed was she fresh for to devise;\n"
"Her yellow hair was braided in a tress,\n"
"Behind her back, a yarde long I guess.\n"
"And in the garden at *the sun uprist* *sunrise\n"
"She walketh up and down where as her list.\n"
"She gathereth flowers, party* white and red, *mingled\n"
"To make a sotel* garland for her head, *subtle, well-arranged\n"
"And as an angel heavenly she sung.\n"
"The greate tower, that was so thick and strong,\n"
"Which of the castle was the chief dungeon<10>\n"
"(Where as these knightes weren in prison,\n"

"Was even joinant* to the garden wall, *adjoining\n"
"There as this Emily had her playing.\n"
"\n"
"Bright was the sun, and clear that morrowning,\n"
"And Palamon, this woful prisoner,\n"
"As was his wont, by leave of his gaoler,\n"
"Was ris'n, and roamed in a chamber on high,\n"
"In which he all the noble city sigh*, *saw\n"
"And eke the garden, full of branches green,\n"
"There as this fresh Emelia the sheen\n"
"Was in her walk, and roamed up and down.\n"
"This sorrowful prisoner, this Palamon\n"
"Went in his chamber roaming to and fro,\n"
"And to himself complaining of his woe:\n"
"That he was born, full oft he said, Alas!\n"
"And so befell, by aventure or cas*, *chance\n"
"That through a window thick of many a bar\n"
"Of iron great, and square as any spar,\n"
"He cast his eyes upon Emelia,\n"
"And therewithal he blent* and cried, Ah! *started aside\n"
"As though he stungen were unto the heart.\n"
"And with that cry Arcite anon up start,\n"
"And saide, \"Cousin mine, what aileth thee,\n"
"That art so pale and deadly for to see?\n"
"Why cried'st thou? who hath thee done offence?\n"
"For Godde's love, take all in patience\n"
"Our prison*, for it may none other be. *imprisonment\n"
"Fortune hath giv'n us this adversity'.\n"
"Some wick'* aspect or disposition *wicked\n"
"Of Saturn<11>, by some constellation,\n"
"Hath giv'n us this, although we had it sworn,\n"
"So stood the heaven when that we were born,\n"
"We must endure; this is the short and plain.\n"
"\n"
"This Palamon answer'd, and said again:\n"
"\"Cousin, forsooth of this opinion\n"
"Thou hast a vain imagination.\n"
"This prison caused me not for to cry;\n"
"But I was hurt right now thorough mine eye\n"
"Into mine heart; that will my bane* be. *destruction\n"
"The fairness of the lady that I see\n"
"Yond in the garden roaming to and fro,\n"
"Is cause of all my crying and my woe.\n"
"I *n'ot wher* she be woman or goddess, *know not whether*\n"
"But Venus is it, soothly* as I guess, *truly\n"
"And therewithal on knees adown he fill,\n"
"And saide: \"Venus, if it be your will\n"
"You in this garden thus to transfigure\n"
"Before me sorrowful wretched creature,\n"
"Out of this prison help that we may scape.\n"
"And if so be our destiny be shape\n"
"By etern word to dien in prison,\n"
"Of our lineage have some compassion,\n"
"That is so low y-brought by tyranny.\"\n"
"\n"
"And with that word Arcita *gan espy* *began to look forth*\n"
"Where as this lady roamed to and fro\n"
"And with that sight her beauty hurt him so,\n"
"That if that Palamon was wounded sore,\n"
"Arcite is hurt as much as he, or more.\n"
"And with a sigh he saide piteously:\n"
"\"The freshe beauty slay'th me suddenly\n"
"Of her that roameth yonder in the place.\n"
"And but* I have her mercy and her grace, *unless\n"
"That I may see her at the leaste way,\n"
"I am but dead; there is no more to say.\"\n"
"This Palamon, when he these wordes heard,\n"
"Dispiteously* he looked, and answer'd: *angrily\n"
"\"Whether say'st thou this in earnest or in play?\"\n"
"\"Nay,\" quoth Arcite, \"in earnest, by my fay*. *faith\n"
"God help me so, *me lust full ill to play*.\" *I am in no humour\n"
"This Palamon gan knit his browes tway. for jesting*\n"
"\"It were,\" quoth he, \"to thee no great honour\n"
"For to be false, nor for to be traitour\n"
"To me, that am thy cousin and thy brother\n"
"Y-sworn full deep, and each of us to other,\n"
"That never for to dien in the pain <12>,\n"
"Till that the death departen shall us twain,\n"
"Neither of us in love to hinder other,\n"
"Nor in none other case, my leve* brother; *dear\n"

"In every case, as I should farther thee.\n"
"This was thine oath, and mine also certain;\n"
"I wot it well, thou dar'st it not withsayn*, *deny\n"
"Thus art thou of my counsel out of doubt,\n"
"And now thou wouldest falsely be about\n"
"To love my lady, whom I love and serve,\n"
"And ever shall, until mine hearte sterve* *die\n"
"Now certes, false Arcite, thou shalt not so\n"
"I lov'd her first, and tolde thee my woe\n"
"As to my counsel, and my brother sworn\n"
"To farther me, as I have told beforn.\n"
"For which thou art y-bounden as a knight\n"
"To helpe me, if it lie in thy might,\n"
"Or elles art thou false, I dare well sayn,\"\n"
"\n"
"This Arcita full proudly spake again:\n"
"\"Thou shalt,\" quoth he, \"be rather* false than I, *sooner\n"
"And thou art false, I tell thee utterly;\n"
"For par amour I lov'd her first ere thou.\n"
"What wilt thou say? *thou wist it not right now* *even now thou\n"
"Whether she be a woman or goddess. knowest not*\n"
"Thine is affection of holiness,\n"
"And mine is love, as to a creature:\n"
"For which I tolde thee mine aventure\n"
"As to my cousin, and my brother sworn\n"
"I pose*, that thou loved'st her beforn: *suppose\n"
"Wost* thou not well the olde clerke's saw<13>, *know'st\n"
"That who shall give a lover any law?\n"
"Love is a greater lawe, by my pan,\n"
"Than may be giv'n to any earthly man:\n"
"Therefore positive law, and such decree,\n"
"Is broke alway for love in each degree\n"
"A man must needes love, maugre his head.\n"
"He may not flee it, though he should be dead,\n"
"*All be she* maid, or widow, or else wife. *whether she be*\n"
"And eke it is not likely all thy life\n"
"To standen in her grace, no more than I\n"
"For well thou wost thyselfe verily,\n"
"That thou and I be damned to prison\n"
"Perpetual, us gaineth no ranson.\n"
"We strive, as did the houndes for the bone;\n"
"They fought all day, and yet their part was none.\n"
"There came a kite, while that they were so wroth,\n"
"And bare away the bone betwixt them both.\n"
"And therefore at the kinge's court, my brother,\n"
"Each man for himselfe, there is no other.\n"
"Love if thee list; for I love and aye shall\n"
"And soothly, leve brother, this is all.\n"
"Here in this prison musten we endure,\n"
"And each of us take his Aventure.\"\n"
"\n"
"Great was the strife and long between these tway,\n"
"If that I hadde leisure for to say;\n"
"But to the effect: it happen'd on a day\n"
"(To tell it you as shortly as I may),\n"
"A worthy duke that hight Perithous<14>\n"
"That fellow was to the Duke Theseus\n"
"Since thilke* day that they were children lite** *that **little\n"
"Was come to Athens, his fellow to visite,\n"
"And for to play, as he was wont to do;\n"
"For in this world he loved no man so;\n"
"And he lov'd him as tenderly again.\n"
"So well they lov'd, as olde bookes sayn,\n"
"That when that one was dead, soothly to sayn,\n"
"His fellow went and sought him down in hell:\n"
"But of that story list me not to write.\n"
"Duke Perithous loved well Arcite,\n"
"And had him known at Thebes year by year:\n"
"And finally at request and prayere\n"
"Of Perithous, withoute ranson\n"
"Duke Theseus him let out of prison,\n"
"Freely to go, where him list over all,\n"
"In such a guise, as I you tellen shall\n"
"This was the forword*, plainly to indite, *promise\n"
"Betwixte Theseus and him Arcite:\n"
"That if so were, that Arcite were y-found\n"
"Ever in his life, by day or night, one stound* *moment<15>\n"
"In any country of this Theseus,\n"
"And he were caught, it was accorded thus,\n"
"That with a sword he shoulde lose his head;\n"
"There was none other remedy nor rede*. *counsel\n"
"But took his leave, and homeward he him sped;\n"
"Let him beware, his necke lieth *to wed*. *in pledge*\n"
"\n"
"How great a sorrow suff'reth now Arcite!\n"
"The death he feeleth through his hearte smite;\n"
"He weepeth, waileth, crieth piteously;\n"
"To slay himself he waiteth privily.\n"
"He said; \"Alas the day that I was born!\n"
"Now is my prison worse than beforn:\n"
"*Now is me shape* eternally to dwell *it is fixed for me*\n"
"Not in purgatory, but right in hell.\n"
"Alas! that ever I knew Perithous.\n"
"For elles had I dwelt with Theseus\n"
"Y-fettered in his prison evermo'.\n"
"Then had I been in bliss, and not in woe.\n"
"Only the sight of her, whom that I serve,\n"
"Though that I never may her grace deserve,\n"
"Would have sufficed right enough for me.\n"
"O deare cousin Palamon,\" quoth he,\n"
"\"Thine is the vict'ry of this aventure,\n"
"Full blissfully in prison to endure:\n"
"In prison? nay certes, in paradise.\n"
"Well hath fortune y-turned thee the dice,\n"
"That hast the sight of her, and I th' absence.\n"
"For possible is, since thou hast her presence,\n"
"And art a knight, a worthy and an able,\n"
"That by some cas*, since fortune is changeable, *chance\n"
"Thou may'st to thy desire sometime attain.\n"
"But I that am exiled, and barren\n"
"Of alle grace, and in so great despair,\n"
"That there n'is earthe, water, fire, nor air,\n"
"Nor creature, that of them maked is,\n"
"That may me helpe nor comfort in this,\n"
"Well ought I *sterve in wanhope* and distress. *die in despair*\n"
"Farewell my life, my lust*, and my gladness. *pleasure\n"
"Alas, *why plainen men so in commune *why do men so often complain\n"
"Of purveyance of God*, or of Fortune, of God's providence?*\n"
"That giveth them full oft in many a guise\n"
"Well better than they can themselves devise?\n"
"Some man desireth for to have richess,\n"
"That cause is of his murder or great sickness.\n"
"And some man would out of his prison fain,\n"
"That in his house is of his meinie* slain. *servants <16>\n"
"Infinite harmes be in this mattere.\n"
"We wot never what thing we pray for here.\n"
"We fare as he that drunk is as a mouse.\n"
"A drunken man wot well he hath an house,\n"
"But he wot not which is the right way thither,\n"
"And to a drunken man the way is slither*. *slippery\n"
"And certes in this world so fare we.\n"
"We seeke fast after felicity,\n"
"But we go wrong full often truely.\n"
"Thus we may sayen all, and namely* I, *especially\n"
"That ween'd*, and had a great opinion, *thought\n"

"Upon that other side, Palamon,\n"
"When that he wist Arcita was agone,\n"
"Much sorrow maketh, that the greate tower\n"
"Resounded of his yelling and clamour\n"
"The pure* fetters on his shinnes great *very <17>\n"

"\"Alas!\" quoth he, \"Arcita, cousin mine,\n"
"Of all our strife, God wot, the fruit is thine.\n"
"Thou walkest now in Thebes at thy large,\n"

"Thou mayst, since thou hast wisdom and manhead*, *manhood, courage\n"
"Assemble all the folk of our kindred,\n"
"And make a war so sharp on this country\n"
"That by some aventure, or some treaty,\n"
"Thou mayst have her to lady and to wife,\n"
"For whom that I must needes lose my life.\n"
"For as by way of possibility,\n"
"Since thou art at thy large, of prison free,\n"
"And art a lord, great is thine avantage,\n"
"More than is mine, that sterve here in a cage.\n"
"For I must weep and wail, while that I live,\n"
"With all the woe that prison may me give,\n"
"And eke with pain that love me gives also,\n"
