In his book The British Mariners Guide (London, ) he gave detailed instructions on how to use and rectify this.
The first Western civilization known to have developed the art of navigation at sea were the Phoenicians, about 4, years ago (c.

a hand instrument used chiefly at sea to measure the altitude of the sun or other celestial body in ascertaining the vessel's position. It consists of a frame in the form of an octant having a graduated scale upon its arc, and an index arm, or alidade pivoted at its apex.
Mirrors, called the index glass and the horizon glass, are fixed one upon the index arm and the other upon one side of the frame, respectively.

That is. The text in the book shown states that it is not for use ashore. The instructions to masters explains that it is to allow sailors on short coastal voyages to obtain their rations in advance to cover periods afloat between ports.
