Protractor (reverse)

Add to album

This is the reverse of a semicircular brass protractor used to set up and measure angles. Dating from 1660, it was probably made by Henry Sutton, a scientific instrument maker based in London from about 1649 to 1665.

The protractor is pierced with two quarter windows and has pricking holes at the centre and at 90 degrees. It is divided into half degrees. There is a scale below the diameter of the protractor.

Sutton was an important figure, known particularly for his skill as an engraver. He died in the Great Plague in 1665..
