Philippe de Champaigne, Saints Gervasius and Protasius Appearing to St. Ambrose
Oil on canvas
Musée du Louvre, Paris
The artist provides a quite literal image of St. Ambrose's vision as described in the Golden Legend, with the young saints in white, St. 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.
