Details 440 came from Boy with a Drawing by Giovanni Francesco Caroto. The drawing is the interesting bit. This scrawly stick-man may be the first attempt to do child-art in a European painting - centuries before psychologists and artists got seriously interested in the subject. Like many adult imitations of children's drawings, it doesn't seem quite plausible. The face and head look more sophisticated than the limbs (and the profile study of an eye, on the side of the sheet, suggests a higher level altogether). Or did Renaissance children develop differently? Caroto, a Veronese artist, lived from 1480 to 1546. The picture has no certain date. It's in the Museo di Castelvecchio, Verona.
