As a result of a tragic stone-throwing game with his Florentine compatriots, Andrea del Verrocchio kills Antonio di Domenico, a woodworker aged 14. He is imprisoned and tried for involuntary manslaughter, but released soon afterward, the judges being used to stone-throwing cases, not unusual in in Florence. Verrocchio is guilt-stricken for the rest of his life, and it’s thought the accidental death was the reason he didn’t put a stone in the hand of his celebrated David.
Leonardo da Vinci produces a pen and ink drawing of the Arno valley that is dated to this day. It is said to be one of the earliest Italian landscape drawings that focuses on the particular character of the location.
