Theodolite

Surveying instrument for measuring vertical and horizontal angles, invented in 1571 by a British mathematician, Thomas Digges, but developed by engineer Jesse Ramsden c.1790. It incorporates a small telescope which moves horizontally and vertically, and often a magnifying lens and spirit level.
