it was sold at auction to an anonymous buyer for $2 million. The palimpsest holds seven treatises, including the only surviving copy of On Floating Bodies in the original Greek. It is the only known source of The Method of Mechanical Theorems, referred to by Suidas and thought to have been lost forever. Stomachion was also discovered in the palimpsest, with a more complete analysis of the puzzle than had been found in previous texts. The palimpsest was stored at the Walters Art Museum in Baltimore, Maryland, where it was subjected to a range of modern tests including the use of ultraviolet and light to read the overwritten text. It has since returned to its anonymous owner. The treatises in the Archimedes Palimpsest include: On the Equilibrium of Planes On Spirals Measurement of a Circle On the Sphere and Cylinder On Floating Bodies The Method of Mechanical Theorems Stomachion Speeches by the 4th century BC politician Hypereides A commentary on Aristotle's Categories Other works Legacy Sometimes called the father of mathematics and mathematical physics, Archimedes had a wide influence on mathematics and science. Mathematics and physics Historians of science and mathematics almost universally agree that Archimedes was the finest mathematician from antiquity. Eric Temple Bell, for instance, wrote: Likewise, Alfred North Whitehead and George F. Simmons said of Archimedes: Reviel Netz, Suppes Professor in Greek Mathematics and Astronomy at Stanford University and an expert in Archimedes notes: Leonardo da Vinci repeatedly expressed admiration for Archimedes, and attributed his invention Architonnerre to Archimedes. Galileo called him "superhuman" and "my master", while Huygens said, "I think Archimedes is comparable to no one" and modeled his work after him. Leibniz said, "He who understands Archimedes and Apollonius will admire less the achievements of the foremost men of later times." Gauss's heroes were Archimedes and Newton, and Moritz Cantor, who studied under Gauss in the University of Göttingen, reported that he once remarked in conversation that “there had been only three epoch-making mathematicians: Archimedes, Newton, and Eisenstein." The inventor Nikola Tesla praised him, saying: Honors and commemorations There is a crater on the Moon named Archimedes () in his honor, as well as a lunar mountain range, the Montes Archimedes (). The Fields Medal for outstanding achievement in mathematics carries a portrait of Archimedes, along with a carving illustrating his proof on the sphere and the cylinder.
