Medium image of Inv Num 35285 - Persian Quadrant

Quadrants can be used for measuring the altitude of astronomical objects such as the stars, or for land-based surveying purposes. Like the astrolabe, quadrants were also used to solve problems of trigonometry.

This quadrant, far less ornate than the astrolabe, clearly served a more practical role and was not simply acquired for prestige.

Inventory no. 35285
Persian Quadrant, 1781/2
