Galileo's Instruments

These images of Galileo and his instruments were scanned in 2001 from Studies in the History and Method of Science, Volume ii. edited by Charles Singer (Oxford: At the Clarendon Press, 1921). The paper in which they appear is "The Scientific Works of Galileo (1564-1642) [:] With Some Account of His Life and Trial [;] Being a Review of Favaro's Edizione nazionale delle Opera di Galileo (1890-1909)" by J. J. Fahre. Both the original images and the scans of them are in the public domain.

This image comprises the left portion of Plate XL, which appears between pages 226 and 227. The instrument identified here as the "Military Compass" is now more commonly referred to as the "Sector." It is a computing device, not a drawing instrument. See especially:

Galileo's Telescopes

This image comprises the right portion of Plate XL, which appears between pages 226 and 227.
