Wikipedia: The Archimedes Palimpsest is a palimpsest (ancient overwritten manuscript) on parchment in the form of a codex (hand-written. The subject of this website is a manuscript of extraordinary importance to the history of science, the Archimedes Palimpsest. Who was Archimedes? Born: About BC in Syracuse, Sicily. At the time Syracuse was an independent. Greek city-state with a year history. Died or.

Less attention was given to the Stomachiona problem treated in the palimpsest that appears to deal with a children’s puzzle. The manuscript currently belongs to an American private collector The palimpsest remained near Jerusalem through at least the 16th century at the isolated Greek Orthodox monastery of Mar Saba. The original Archimedes manuscript was a fairly large book, archimeves 20 cm wide and 30 cm tall.

In other words, the measured gray values of pixels that contain Archimedes text are approximately the same as those from the surrounding parchment when viewed in red light, so they cannot be distinguished. Heiberg had photographs taken of many pages of the manuscript though not alland published his results in as the three volumes of Archimedes, Opera omnia.

All sorts of information about the Archimedes Palimpsest and the project to retrieve its text can be found on this site, and there is even more to see in the exhibition.

Abigail Quandt performing the conservation of the manuscript. These translations had to be removed to “register” the images before performing the multispectral processing.


Heiberg was permitted palimpzest take careful photographs of the palimpsest’s pages, and from these he produced transcriptions, published translatuon and in a complete works of Archimedes. This explanation is contained in The Method.

The most promising ideas are the application of optical character recognition to the images, and imaging of the difficult pages using X-Ray fluorescence imaging. Initially in competition, these two teams have subsequently collaborated on the production of images for the scholars. No pieces have been identified as such; the rules for placement, such as whether pieces are allowed to be turned over, are not known; and there is doubt about the board.

For the Codex board again as with Tangram there are three ways to pack the pieces: Paimpsest facilitate this process in conjunction with the standard method, a second camera head has been added to the x-y translation table. The condition that the two figures balance now allows him to calculate the total mass of the other figure.

In multispectral imaging, digital images are collected of the same “scene” using light at a variety of wavelengths. The resulting Archimedes text is “bright” in the red and “dark” in the green and blue, thus producing palimpseat “reddish” tint actually magentawhile the Euchologion text appears as a “neutral” gray.

Threads collapsed expanded unthreaded. The project, which is in its twelfth year, has generated a great deal of public curiosity, as well as the interest of scholars throughout the world. Nigel Wilson of Lincoln College, Oxford, individually analyze the processed images to read the original text.


These new texts include speeches by an Athenian pxlimpsest from the fourth century B. For explicit details, see Archimedes’ use of infinitesimals. Scholars have long used ultraviolet lights to read palimpsests because the organic material in parchment “fluoresces,” meaning that the parchment absorbs the short-wavelength photons from the illumination and then re-emits.

Keith Knox, then of the Xerox Corporation, had collaborated with one of the authors for several years on the subject of imaging historical manuscripts, including the Dead Sea Scrolls. The Archimedes Palimpsest Item Preview.
