Latona and the Lycian Peasants, Jan Brueghel the Elder
Ostensibly, this is a scene from classical mythology, showing the goddess Latona getting pissed at the peasants who are blocking her from getting a drink and turning them into frogs.
I think it’s pretty obvious, however, that what Brueghel was really interested in was the landscape — at the time not an accepted subject for painting in itself.
