The symbol of St Luke is a winged ox. The ox was a sacrificial animal and the second chapter of St Luke's Gospel refers to a sacrifice.
The Bible says that Luke was a 'physician', but he was also believed to have been a painter. He is therefore the patron saint of both doctors and painters, and is sometimes shown making a portrait of the Virgin.
