St. Luke (S. Lvcas)

St. Luke sits at a table writing his gospel in a book. He writes with a quill pen in his right hand and holds the book open with his left. He is accompanied by his attribute, the ox which appears just behind the Saint's shoulder at right. Behind him, at left, a painting is shown on an easel, a reference to the legend that Saint Luke was an artist and that he painted the first portrait of the Virgin.
