What did Ptolemy do geography?
Ptolemy’s most important geographical innovation was to record longitudes and latitudes in degrees for roughly 8,000 locations on his world map, making it possible to make an exact duplicate of his map.
Who was Ptolemy and what did he do for geography?
Claudius Ptolemy was a Greek mathematician, astronomer and geographer. Much of medieval astronomy and geography were built on his ideas: his world map, published as part of his treatise Geography in the 2nd century, was the first to use longitudinal and latitudinal lines.
Where was Ptolemy located?
Alexandria
Ptolemy lived in the city of Alexandria in the Roman province of Egypt under the rule of the Roman Empire, had a Latin name (which several historians have taken to imply he was also a Roman citizen), cited Greek philosophers, and used Babylonian observations and Babylonian lunar theory.

What is Ptolemy theory?
The Ptolemaic system was a geocentric system that postulated that the apparently irregular paths of the Sun, Moon, and planets were actually a combination of several regular circular motions seen in perspective from a stationary Earth.
What was Ptolemy trying to explain?
The most important solution to this problem was proposed by Claudius Ptolemy in the 3rd century AD. He argued that planets move on two sets of circles, a deferent and an epicycle. This explained retrograde motion while keeping the planets in their circular orbits around the Earth. Ptolemy’s last device was the equant.
Why is Ptolemy famous?
Ptolemy made contributions to astronomy, mathematics, geography, musical theory, and optics. He compiled a star catalog and the earliest surviving table of a trigonometric function and established mathematically that an object and its mirror image must make equal angles to a mirror.
