The Life of Archimedes. Birth: About BC in Syracuse, Sicily (At the time it was still an Independent Greek city-state). Death: or BC in Syracuse. This famous book, known as the Archimedes Palimpsest (AP), contains Greek unbound manuscript in which much of the Archimedes text was hidden, and. 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.

P clones matching plant DNA. Creation of Clone Libraries and Sequence Analysis To obtain a detailed phylogenetic identification of the microbial community members, clone libraries containing either ITS fungal regions fungal community or 16S rRNA gene fragments bacterial communities were carried out.

The resulting sequences of the bacterial and fungal clones have been deposited at the GenBank: genetic sequence database at the National Center for Biotechnical Information. To enable the quantification of PCR products, standard curves based on threshold cycles were produced by re-amplifying tenfold dilution series of PCR products from genomic DNA.

An aliquot of each dilution 0. The resulting PCR products were used to construct standard curves for absolute quantification. A chemical characterization of the inorganic constituents of the samples was performed by means of electron dispersive spectroscopy EDS.

Reference elemental intensities acquired from pure compounds standards are commonly utilized for calibrating SEM-EDX systems. In the case study described in this paper, conventional ZAF correction 13 integrated into an Oxford INCA microanalysis package was applied to the spectrum dataset Oxford Instruments. The EDS measurements were taken at several points across the surface of both the hair and flesh sides of the three core samples.

Each measurement was then repeated in at least three areas to obtain up to 60 repeated measurements for each sample on each side.

The data obtained was used for a series of comparisons aimed at evaluating the relationships between the variables and the significance of the differences between the damaged and healthy parchment cores.

PCA was used to study and visualize the correlations between all the variables chemical elements [ 28 ]. The first few principal components PCs resulting from PCA are generally utilized to analyze the common features among samples and their grouping: samples characterized by similar elemental signatures tend, in fact, to aggregate in the score plot of the first two or three components.

Samples characterized by similar elemental composition are thus grouped in the same region of the score plot related to the first two PCs, whereas samples with different elemental features are clustered in other parts of this space. PCR analysis using bacterial- and fungal-specific primers showed positive results. This technique enabled an estimation of the most abundant organisms inhabiting this unusual parchment object, their comparison among the different sampled areas, as well as the screening of the cloned sequences.

The DGGE profiles obtained from the swab samples as well as from the corresponding sequenced clones are shown in Fig. DGGE fingerprints derived from bacterial 16S rDNA amplified from the three independent cotton swabs were shown to be identical data not shown.

Therefore, aliquots of these DNAs were pooled for the construction of a single bacterial clone library Fig. Phylogenetic Identification of the Microbial Communities Colonizing the Parchment To accomplish phylogenetic identification of the bacterial and fungal communities inhabiting the parchment folios of the Archimedes Palimpsest, clone libraries containing the 16S rDNA one clone library or the ITS fragments three clone libraries were generated.

Clones were screened by DGGE and those displaying different fingerprints were grouped. Finally, one representative of each group was selected for sequencing Fig. It investigates the history of the palimpsest, citing new data and formulating interesting hypotheses, especially regarding the period that intervened between the previous legal owner of the manuscript, i.

During this interval of approximately eight decades, from the s to , the manuscript passed through the hands of at least two other owners, the dealer and collector Salomon Guerson and a French family, who were related by marriage to the Guerson family. By , he was dealing in single-leaf miniatures cut from their parent volume. Rather, the intriguing question is whether the download was indeed legal.

The Patriarchate of Jerusalem argues that the manuscript could only have been sold upon instructions from the Patriarch himself and that such an instruction was never given. Plimpton—who is known in the history of mathematics from the famous old- babylonian clay tablet that bears his name Plimpton —attempted to download the manuscript legally on an earlier date in , but the reply he received through I.

Moreover, the possibility that the manuscript was sold by some monk without permission from the Patriarch cannot be ruled out, although it would not have constituted a legal sale. Heiberg regarding the conditions under which he studied the manuscript in indicated anything but indifference to issues of security on the part of the monks, at least at that period.

In particular, in a letter to his friend and colleague A. Drachmann, Heiberg wrote about his working conditions at the Metochion that the monks did not allow him to work alone with the manuscript. He was permitted to work for 6 hours per day including Sunday p. Furthermore, the manuscript did not leave the monastery even to be photographed; the photography commissioned by Heiberg in was done by the Constantinople photographer Guillaume Berggren in situ p.

As part of the project to conserve and study the Palimpsest, Abigail Quandt was responsible for the conservation from the outset.

Archimedes Palimpsest Metadata Standard

Here one can find information about the imaging project of the manuscript, the techniques that were used, and the digital data set. It is worth noting here that from the first moment the palimpsest project was laid down, a fully transparent approach was adopted with respect to the production and end product of the digital counterpart of the physical manuscript. The decision by the owner of the manuscript and the imaging team to allow free access to the digital images, but also to the know-how of their production and processing, is praiseworthy and constitutes an example to be followed for other analogous databases.

Christens-Barry, Roger L. Easton Jr. Knox pp. Toth pp. If the owner of the Palimpsest is interested in putting the manuscript on view, he might consider that the Walters is an appropriate place. Please excuse this cold call. It is just a thought, but from our point of view an exciting one, given the extraordinary cultural importance of the codex.

Whatever you think of this I would, as I say, look forward to hearing from you and receiving your catalogues. With many thanks for your time, William Noel Curator of Manuscripts and Rare Books I moved my cursor to the top left of the screen: send. By the next minute I had dismissed it from my mind. Still, I had done my job. Emails are short on ritual. They just pop up unbidden on your computer screen while you are engrossed in your daily business.

Some of them, like little electronic terrorists, can blow your mind and change your life. Three days after my email to Finch this happened to me. Sam Fogg. I think the downloader of the Palimpsest is very sympathetic to the idea of sending the Archimedes to the Walters. I have already suggested to him that we visit the Museum in January. Perhaps we could discuss this and the Archimedes on the telephone soon. Best wishes, I sat motionless in my chair—eyes shut, hands cradled behind my head, rocking gently, my stomach slowly turning to wax.

Then I picked up the phone and dialed a number. It was a number I knew almost by heart. Sam is savvy, suc- cessful, and very smart.

I arranged a flight to London. Before I caught the plane I discussed strategy with Gary. He thought that Simon Finch and Sam Fogg might actually be the same person and that I was being given the runaround. It was only at this lunch that I dis- covered who the owner of the Palimpsest actually was. He had in fact been present at the auction, unnoticed by the competition, and unrecognized by the press.

He still likes to tell the story. Moreover, he had known exactly the liability that he was trying to download and had bought it on the assumption that he would deposit it somewhere for conservation and scholarly study. His anonymity was important to him and hereafter he became known in any written correspondence as Mr. We agreed that Sam and Mr.

B would visit the Walters in January. This was just great. My brother Rob had written a story about a dog-eared palimpsest once and so I had the vague, romantic notion that palimpsests could harbor secret knowledge that you could only understand if you were really smart.

But that was all I could remember.

I needed a few facts and a map of the Mediterranean. It was November. I had two months to learn enough not to look like a total idiot. B and Sam arrived at the museum. I met them at the entrance. Sam was a laugh a minute, as he always is; Mr. B was com- pletely silent. Nervous to begin with, I took them up to the manu- script room, a climate-controlled vault that serves as my office as well as the repository of hundreds of medieval treasures.

I entertained Sam and Mr. B for an hour or so, before taking them to have lunch with Gary. On the way, Sam walked in front with Gary, and I walked behind with Mr. B—a nervous puppy trying to come to grips with the biggest fish of my little career.

I remember congratulating him on his exciting new acquisition and saying that it was extremely generous of him to even consider putting his great new treasure on deposit at the Walters.

His reaction to this was my first lesson in the mind of Mr.

He said that he had already left it on deposit with me. I did not understand. I asked him to say it again. He said that he had left it in a bag on my desk. I swallowed hard.

As a museum registrar will quickly point out, this does not conform to standard museum protocols for the transportation and documentation of objects worth several mil- lions of dollars. I went with the flow. Great, I told him, and I reassured him that I had locked the door of my office on the way out. Lunch was cordial, but a little odd to me. As I have said, Mr.

B enjoys his food, and he also likes to take his time. I wanted to go back to the museum and look at the manuscript. I was quite happy with one course; Mr.

B wanted his chocolate sundae. B out of his.

Eventually lunch was over and the check was requested. Gary tried to pay with a credit card. This is Baltimore. I paid cash. Back we walked to the museum. I made my excuses on the way and ducked away to download a pack of cigarettes. I caught up with them in time to turn the key to the manuscript room where my desk sits.

A lightweight blue bag was on my desk. I unzipped the bag and pulled out a brown box. We opened the box. Inside was a small, thick book. The cover was made of battered leather and was badly stained. On the upper cover there was a flash of red paint and an odd silver-looking stud. Abigail placed the book between two velvet-covered blocks of wood on the table. The blocks prevented the manuscript from opening too far and placing unnecessary strain on the binding and the pages.

She opened the book just far enough so that we could see inside. B, Gary, and I all peered over her shoulder.

At first I saw nothing. Only slowly did my eyes adjust. And then the awesome thought dawned on me.

I was looking at the unique key to the mind of a genius who had died 2, years earlier. I could barely see it to read it, and I would not have understood it if I could, but there it was nonetheless.I did not understand.

The same is true of the texts it contains, which prove the very high standards attained today by scholarship in classical studies and in the history of mathematics, but also the level of progress achieved in the technology of retrieving underlying writings from artefacts. Secondly, this manu- script is a palimpsest.

PCR conditions were as described by Schabereiter-Gurtner et al. The result is that when one reads the transcribed Greek text, one has the sense of reading the manuscript, and indeed with much greater ease, since reading the printed Greek text does not require knowledge of palaeography as does reading the original manuscript.
