A spectacular mosaic in the Old Baptistery of the church, which a Greek inscription dates to August 531 AD. It was protected under a plainer mosaic from 597 until 1976. It depicts animals, farmers and hunters in four tableaux surrounded by geometric decoration. At the top, a tethered zebu is protected by a shepherd fighting off a huge lion and a soldier lancing a lioness. Meanwhile, two mounted hunters with dogs spear a bear and a wild boar.
