Horseman of the Apocalypse
by GIOTTO di Bondone, Fresco
The four fields in the crossing vault of the lower church are framed by broad, heavily ornamented borders with diamond-shaped, small format picture fields, all filled with motifs from the Apocalypse, including the four horsemen of the Apocalypse. The focus of this subsidiary pictorial program is the Apocalyptic Christ in the capstone of the crossing vault.
