This print reproduces a painting of 1864 (now in the Pushkin Museum, Moscow), depicting Praetextatus, Bishop of Rouen from 549 to 586, on his death-bed, accusing the Merovingian Queen Fredegund of ordering his assassination (the two had long been enemies). The story is told in Gregory of Tours’ History of the Franks.

The lithographer was born in Ghent.
