Pan, the lustful god of the woods and fields, pursues the Arcadian nymph Syrinx to the banks of the river Landon, which blocks her escape. In order to avoid his clutches, she prayed to be transformed into the reeds that Pan finds himself unexpectedly embracing (Metamorphoses I: 689-713). The subject was a favorite of De Troy, and he painted it in the early 1720s in smaller variant versions in the J. Paul Getty Museum, Los Angeles (no. P.81) and the Cleveland Museum of Art (no. P.84).
