Description
This instrument was made by the London scientific instrument maker Robert Brettell Bate (1782–1847).
The protractor is a drawing instrument, used for measuring and drawing angles. Protractors began to appear in the sixteenth century, often in sets of drawing instruments which also included rulers, scales, dividers, squares and sectors, and were originally used with sea charts.
This 360° circular protractor, used for measuring and drawing angles, is marked both with degrees and with the points of the compass. For more on Bate’s life and works, see Wh.6262.
