The Ptolemies try to collect every book in the world, and scholars flock to read them.
Founded in the early 3rd century BCE by Ptolemy I or II, the library may have held tens of thousands of papyrus scrolls. Scholars there, including Euclid, Eratosthenes and Callimachus, who created the Pinakes catalogue, made it the model of a research library.
