A visual comparison and historical survey is made between the work of Francesco da Sangallo and a bronze group of nude men riding beasts, presently attributed to Michelangelo.
Examined is the discovery of an engraved rock crystal evidently serving as the master prototype for a quantity of late 15th century bronze plaquettes. A relationship of the rock crystal with Lorenzo de’ Medici is drawn by way of a relationship with its subject: a Head of Pan. Also discussed is the crystal’s reproduction in a sketch by a young Michelangelo and finally surveyed is the curious loss of the object’s meaning in exchange for what would become a universally vilified image of Attila the Hun.
A popular pax after Michelangelo’s Pieta for Vittoria Colonna and a Deposition pax are here suggested as the product of Ludovico and/or Jacopo del Duca while a later variant of Michelangelo’s Pieta, formed as a pax, is given to a Venetian workshop active in the first part of the 17th century.
