Giovanni Domenico Ferretti

This Florentine painter had a habit of signing his paintings with a tiny self-portrait hidden in the corner, like a secret handshake. He was the go-to artist for grand ceilings in palaces, where he’d pack in so many figures that clouds looked like they were holding their breath. Grab a map of Florence and hunt down his *Allegory of the Medici Family* in Palazzo Corsini—look for the cherubs who look like they’ve just been told to sit still.
