Chromolithograph designed by Michelangelo Caetani, from his The Divine Comedy of Dante Alighieri Described in Six Plates. The images appeared in two editions, the first in 1855 featured hand-colored lithographs and a second in 1872 using an early form of chromolithography, deployed by an order of monks at Monte Cassino near Rome.
