Philippe de Champaigne, Saints Gervase and Protase Appearing to St. Ambrose

Oil on canvas
Musée du Louvre

The artist provides a quite literal image of Ambrose's vision as described in the Golden Legend, with the young saints in white, Paul in his long beard and balding pate, and Ambrose at prayer. One detail the artist suppressed was the boots that Ambrose had seen on the two youths. Perhaps the boots seemed inconsistent with the dreamy quality of the painting as a whole.
