The image closely follows a passage in the Golden Legend. The magician Hermogenes (in the red garment) had sent devils to capture James and his convert Philetes (in the blue cape), but James commanded them to go back, bind up Hermogenes, and bring him to James. Returning "good for evil, as Christ taught us," James tells Philetus to unbind Hermogenes. Then he gives Hermogenes his staff so that the devils cannot harm him. This leads to Hermogenes' conversion, which in turn leads to a decision of the authorities in Jerusalem to put James to death.

According to the Web Gallery of Art, this is one of four extant panels from the predella of an unidentified altarpiece. None of the other panels features St. James the Greater.
