The tomb monument was the first collaboration between Donatello and Michelozzo, who went on to collaborate on the tomb of Cardinal Rainaldo Brancacci in the Church of Sant'Angelo a Nilo in Naples, the tomb of Papal Secretary Bartolomeo Aragazzi in what is now the Duomo of Montepulciano, and the external pulpit of the Duomo of Prato. At the time of their partnership, Donatello was already well known for his statues of prophets and saints for the Duomo and Orsanmichele, while Michelozzo was more obscure. Both had worked for a time for Ghiberti, whose workshop then led Florentine sculpture.
