The Harvesters (1565) by Pieter Bruegel the Elder

It’s a hot, dry summer and the harvest is in full swing; workers take a break for beer, bread and cheese; a man lies stretched out under the pear tree, mid-snore. And that’s just the foreground: in the background, apple-scrumping, wild swimming, village revels and some "very joyful buttocks"!
