Paula Findlen in The Nation:
A right thumb, a finger, a tooth. These were the contents of a reliquary acquired several years ago by a collector at an auction in Florence. Little did he know that for centuries the remains had been objects of profane devotion. Last seen in 1905, they had been sliced from the corpse of Galileo, along with another finger and a vertebra, during his highly publicized reburial in the Basilica of Santa Croce in 1737 almost 100 years after his death, and preserved in a slender case fashioned of glass and wood and crowned with a carved bust of the scientist. The reliquary’s new owner consulted Galileo experts about his find, and after the authenticity of its contents had been verified he donated it to the Museo Galileo, which is tucked behind the Uffizi in a quiet piazza overlooking the River Arno. (A dentist asked by the museum to examine the tooth concluded that Galileo suffered from gastric acid reflux and ground his teeth in his sleep.) The rediscovered reliquary is displayed adjacent to a smaller one containing Galileo’s other finger, a prized museum possession since 1927. Nearby are several artifacts of Galileo’s scientific genius: a telescope presented to the Medici and the broken objective lens of the original device with which Galileo sighted Jupiter’s four satellites in 1610.
