Historians used to wonder if Giuseppe Arcimboldo was a madman, assembling human faces from vegetables and flowers. But Arcimboldo was just wildly creative. Spring is from his Four Seasons collection — a suite of paintings showcasing the literal fruits of the prosperous reign of Emperor Maximilian II. The Emperor loved the work so much, he had Arcimboldo reproduce the paintings multiple times, so he could send them to his friends and family.
