Historic Period

16th-17th C.


Description

Compass used for surveying, generally consisting of two flat graduated legs, a magnetic compass in the hinged joint and sighting devices. In its simplest form, this type of compass is well represented by the so-called florentine archimeter. In a version described by Giacomo Contarini, which may have been invented by Fabrizio Mordente, the instrument has two graduated legs with a magnetic compass in the joint, a graduated arm also pivoted at the joint, two small graduated arms connected to cursors sliding along the legs, and a 180° graduated arc.
