Astronomy was an important subject thought at schools in Eastern Rome. Astronomers, mathematicians, and philosophers were not uncommon during the rule of Rome in the East.
Ptolemy, the most famous astronomer of ancient times, lived in Alexandria during the Roman rule. Alexandria was the largest city in the Mediterranean, and surprisingly, was also located in Egypt.
Ptolemy wrote Almagest in the city of Alexandria. It wasn’t the first astronomy book written, but it was the most encapsulating and consistent one. Almagest became a handbook for astronomy for many generations to come. It has been translated into Arabic first. And after that Latin, Greek, French, German and in time almost every language. Ptomely has become a legend among Europeans and has been given the name “King of Alexandria”.
