Saint LukeSaint Luke was an Apostle and one of the four evangelists. His symbol as an evangelist is a winged ox. He probably wrote the Acts of the Apostles, as well as his Gospel. He is supposed to have been a doctor.
According to legend, Luke painted a picture of the Virgin Mary; because of this he is regarded as the patron saint of painters. Medieval artists' guilds are usually called Guilds of Saint Luke.
