The library at Alexandria in Egypt became the center of research, literature, and science.

Explanation:

The library in Alexandria was, in ancient times, the largest library in the world and made Alexandria a leading learning center. It is believed that it was founded around 280 BC by Ptolemy II of Egypt. Eratosthenes and Aristarchos actively researched the library, which in its heyday should have had between 400,000 and 700,000 rolls, most of which were papyrus.
