Trigonometry
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.
