Artist's Description
Hipparchus in his observatory in Alexandria. Hipparchus (190-120 BC), was an ancient Greek astronomer, geographer, and mathematician. A methodical observer, Hipparchus compiled the first known star catalogue, listing some 850 stars, as well as their celestial coordinates and magnitude. He was the first whose quantitative and accurate models for the motion of the Sun and Moon survive. He developed trigonometry and constructed trigonometric tables, and he solved several problems of spherical trigonometry. His other reputed achievements include the discovery of Earth's precession and possibly the invention of the astrolabe and the armillary sphere.
