The city of Alexandria is worldwide known for two reasons: the lighthouse and the library. Nothing remains today of these wonders of the ancient times, though.
In 295 b.c, the Egyptian ruler Ptolemy I commissioned the construction of thegreat library of Alexandria. In the following years, local scientists traveled through the region to purchase books for the library. In times of Ptolemy III some of the more important books in the world were copied. The library also held originals of Aeschylus, Euripedes and Sophocles, and most probably the largest Greek collection, the library of Aristotle. The ancient library had 500,000 scrolls. All human knowledge was stored here, but its more important role was as a center for scientists and philosophers.
