A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία (gōnía) 'angle' and μέτρον (métron) 'measure'. The first known description of a goniometer, based on the astrolabe, was by Gemma Frisius in 1538. (Wikipedia).
