One of the standard illustrations in Medieval and later Gospel Books is the Evangelist Portrait. These portraits were almost always full page miniatures and were derived from the Late Antique tradition of author portraits such as those found in the Vergilius Romanus and the Vienna Dioscurides. Evangelist Portraits were often combined with a representation of their symbols. The Evangelists are often shown writing or holding a book or a scroll. All images unless otherwise noted are pigment on parchment.
