The Four EvangelistsThe four authors of the Gospels - Matthew, Mark, Luke and John are known as the Evangelists.
They are often represented with their attributes: the Angel for Saint Matthew, the Lion for Saint Mark, the Ox for Saint Luke and the Eagle for Saint John. Sometimes these symbols stand in for the Evangelists.
Saint Mark is also often shown with a book representing his Gospel. Saint Luke, the patron saint of painters, is sometimes shown painting.
