William Noel: Revealing the lost codex of Archimedes

TL;DR

This content discusses the discovery and preservation of the Archimedes Codex and advocates for institutions to release data under unrestricted licenses.

Transcript

The great texts of the ancient world don't survive to us in their original form. They survive because medieval scribes copied them and copied them and copied them. And so it is with Archimedes, the great Greek mathematician. Everything we know about Archimedes as a mathematician we know about because of just three books, and they're called A, B and...

Key Insights

• 📜 Medieval scribes played a crucial role in preserving ancient texts, including those of Archimedes, whose works survive in just three books, A, B, and C.
• 📘 Codex C, containing Archimedes' texts, was discovered in 1906 buried within a prayer book, and its uniqueness was recognized by Johan Ludvig Heiberg, who transcribed the text by hand.
• 🔎 The Archimedes Codex was in poor condition, suffering from mold and forgeries. However, a private owner purchased it in 1998 and funded the preservation and digitization project to make it accessible to the public.
• 🔬 A team of experts, including conservationists, mathematicians, and imaging specialists, collaborated to restore and examine the Codex.
• 🖼️ Advanced imaging techniques, such as infrared and ultraviolet imaging, were used to reveal the hidden text on the parchment.
• ⚡ Using X-ray fluorescence imaging at the Stanford Synchrotron Radiation Laboratory, researchers mapped the iron in the ink to decipher the Archimedes text.
• 🎓 The discovery of new texts by Archimedes, as well as a lost speech by Hyperides, highlights the importance of digitizing and making ancient manuscripts freely accessible to the public.
• 💻 Institutions should follow the example set by the Codex's private owner, allowing unrestricted access to digitized data to enhance cultural knowledge and appreciation.

Questions & Answers

Q: What is the main reason why the great texts of the ancient world survive today?

The great texts of the ancient world survive because medieval scribes copied and recopied them throughout the centuries.

Q: What happened to Archimedes' books A and B?

Archimedes' book A was lost by an Italian humanist in 1564, while book B was last heard of in the Pope's Library in Viterbo in 1311.

Q: How was Archimedes' Codex C discovered and where is it located now?

Archimedes' Codex C was discovered in 1906 and it is currently located in Baltimore. It was buried within a prayer book.

Q: Why was it important to rescue and preserve the Archimedes Codex?

The Archimedes Codex was bought by a private owner in 1998 to ensure its safety, make its content accessible and free, and preserve a valuable piece of ancient knowledge.

Q: What difficulties were faced during the conservation and imaging process of the Archimedes Codex?

The book had to be taken apart, glue and wax had to be removed, and the pages had to be imaged using various techniques such as infrared, ultraviolet, and X-ray fluorescence imaging.

Q: What discoveries were made within the Archimedes Codex during the imaging process?

Two unique texts by Archimedes were found, titled "The Method" and "The Stomachion." Additionally, a lost speech by Athenian orator Hyperides and a commentary on Aristotle's "Categories" were also discovered.

Q: Why was the data and images of the Archimedes Codex made freely available online?

The owner understood the importance of open data and wanted to ensure its survival and usefulness. Institutions can learn from this and release their own data under unrestricted licenses, benefiting everyone.

Q: What would be the benefit of institutions releasing their data under unrestricted licenses?

Allowing open access to institutions' data would give people the opportunity to curate their own collection of knowledge and increase the beauty and cultural significance of the Internet. It would also help institutions gain exposure and attract more visitors.

Summary & Key Takeaways

• Ancient texts survived through the work of medieval scribes who copied them repetitively.

• Three books, known as A, B, and C, contain all the knowledge about Archimedes as a mathematician.

• Codex C, one of the seven recycled manuscripts used to create a prayer book, was discovered in 1906 and revealed new texts by Archimedes.
