Michelangelo's designs for St. Petronius, St. Proculus and the Candelabrum-Bearing Angel, carved for the Shrine of St. Dominic in Bologna during a stay in the city from 1494 to 1495, illustrate his sensitivity to the object as a visual experience bound to the observer and governed by conditions imposed by the site. The visual evidence provided by these three statuettes in fact demonstrates that, from the beginning of his career as a sculptor, Michelangelo's fundamental ideas concerning figural composition al giudizio dell'occhio, for which he later would become famous, were firmly in place.
