12608 Aesop           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Herodotus Aisopos of Sardes (Aesop) was a slave who lived around 550 B.C. on the island of Samos. The people loved his fine fables so much that he became a free man. Aesop's fables are full of wisdom and have been translated into many languages.
