Title:  

Wood and Ivory Octant with Case
Date:
ca. 1850
Creator:
Rosell, Jose

Content Description: 

Octant. A. This object was used to solve the spherical triangle in celestial navigation. It is constructed primarily of ebony(?), with brass, glass mirrors and an ivory scale. The handle on the right side appears to be ebony wood, as is the frame of the instrument. The ivory scale is graduated in degrees from 0 to 105 with a vernier attachment for greater precision. The metal parts are in fair condition because of corrosion and dirt. B. The case is made from mahogany in the shape of a truncated pie slice. It contains an extra sighting tube.
