Works of Galileo Galilei, Part 1, Volume 16, Records
Galileo Galilei (1564–1642), in addition to being an important scientist and mathematician, was an accomplished instrument maker, who in 1597 invented a military compass to assist in artillery bombardments and other military activities. While occupying the chair in mathematics at the University of Padua, Galileo established a workshop where, assisted by the mechanic Marcantonio Mazzoleni, he built precision instruments, above all compasses, which he then sold to supplement his university stipend. This document contains the list of accounts for the workshop. Recorded are the debits and credits of the shop, along with brief notes and comments, all in Galileo’s own hand.
