This instrument is actually a reproduction of a 17th century Octant.
Despite its inaccuracy in measuring the height of the sun and stars, it
allowed navigators to determine geographical latitude.
The arc of the Octant is 45° or 1/8 of the circumference (hence the
name). The Sextant (1757) replaced the wooden frame with a metal one,
progressively replaced the Octant and continues to be used.
