It wasn't. It was first attributed to Eratosthenes and first used by Ancient Greeks.
Hipparchus was the best astronomers of his time and was a Greek astronomer, geographer, and mathematician. He very accurately cataloged over 1,000 stars. Ptolemy was a great admirer of Hipparchus research and from what I've seen Ptolemy was often said to do what Hipparchus had done.
Hipparchus (190-120 BC), was perhaps the greatest of the Greek astronomers who devised a method of locating geographical positions by means of latitudes and longitudes. Also Ptolemy (2nd century A.D.) was a Greek astronomer and mathematician who lived and worked in Egypt. He wrote the book Geographie which charts all the places of the world as known to them at that time. His works , which employed a system of latitudes and longitudes , influenced map-makers for hundreds of years . He was a cartographer and he evolved the science of map-making.
There are a number of factors that influenced Ptolemy. He was mainly influenced by the intellectual development of Hipparchus of Bithynia among other philosophical aspects of life.
Claudius Ptolemy developed the mathematical astronomy used in Christian and Muslim countries up until the 16Thcentury. Christopher Columbus and Magellan used Ptolemy's version of the world map during their voyage, but they did not know it was incorrect, thus not ending up where they planned to be. He found the position of over one thousand stars.

Claudius Ptolemy synthesized and extended Hipparchus' system of epicycles and encentric circles to ezplain his geocentric theory off the solar system.
He was the first person to explain why the sun and stars move across the sky

I believe it was Claudius Ptolemy. Hipparchus for the GK folks.
Ptolemy never saw a telescope. The first telescopes were invented about 1500 years after Ptolemy died.
It is first mentionned in writing by Ptolemy in the second century AD, however some believe that it was actually named by Hipparchus approx 120BC. It is unlikely that whoever discovered it when will ever be known
Ptolemy was the first person to invent maps
Ptolemy invented the geocentric theory during the second century A.D.
