Joos van Cleve, The Crucifixion: Detail, left panel

St. John the Baptist stands on the left and points to a lamb, an allusion to his remark about Jesus, "behold the lamb of God" (John 1:29,36). He wears a mantle of martyr's red over his camel-skin tunic.

On the right, St. Catherine of Alexandria stands before the wheel that is her primary attribute and holds a book and the sword with which she was martyred. The artist has chosen not to give her the crown that one often sees in her portraits.
