This stone sculpture shows St. Luke, the author of the Third Book of the Gospel and the Acts of the Apostles, seated at a writing desk. He was a medical doctor, and once made a portrait of the Virgin, and therefore he became the patron saint of doctors and artists. The sculpture shows the saint writing or drawing on a tablet, and the angle of his head suggests that he is thinking. One of St. Luke’s symbols was the ox, an animal used in ritual sacrifice, and we see a tiny ox at the lower left of the statue. The scroll carrier above the ox was used to carry parchment documents.
