The Galilean compass, which should not be confused with the drawing compass, is a sophisticated and versatile calculation tool designed to perform several geometric and arithmetic operations by exploiting the proportionality between the homologous sides of two similar triangles. It is composed of three parts: two arms, pivoted in a round disk called nocella, on whose sides (recta and versa) are engraved several scales; the dial, featuring different scales, which is fixed to the holes in the arms of the compass by a screws called wing nuts. and the zanca, a slider inserted into one arm which allows both to hold the compass vertically and to extend the arm in which it’s inserted.
