To refer to Susan Cole, chair of the UB Department of Classics, as a "pigaholic" is extreme, but when it comes to the hog heaven that was ancient Greece, she can wax rhapsodic on the subject of Hellenic porkers. On Jan. 31, Cole, associate professor of classics and a noted humanities scholar, will focus on the ups and downs of Greco swine-life in a lecture called "Pigs for the Gods and Pork for the Table: Dining Out in the Ancient Greek City."
