(1386 - 1466) A Florentine sculptor who helped define Renaissance sculpture as distinct from that of the Gothic period. He is known for St. Mark and St. George in the Orsanmichele [OR-sahn mee-KAY-lay] (a Florentine church), the bald Zuccone (which means 'pumpkin-head,' though it depicts the prophet Habbakuk), and the first equestrian statue to be cast since Roman times, the Gattamelata in Padua. He is also known for mastering the low-relief form schiacciato.
