sextant

sextant: [17] A sextant is etymologically an instrument based on a ‘sixth’ of a circle. Sextants measure off the angle between the horizon and a celestial body on a graduated scale that is marked on an arc equal to one sixth of a circle. They were first named at the beginning of the 17th century by the Danish astronomer Tycho Brahe, who used the term sextāns ‘sixth part’, a derivative of Latin sextus ‘sixth’ (to which English six is closely related). The anglicized version sextant is first recorded in 1628.
