On February 2, 1425, Bartolomeo Valori and Cosimo de' Medici requested 400 of the 800 florins that had been deposited with the Calimala, likely for work already completed. This deposit was insurance in case the executors left the tomb unfinished and the Calimala was forced to pay for its completion, as it had been obliged to with the finger reliquary. This request is also the most direct piece of evidence for Cosimo's involvement with the commissioning. Despite this document, Vasari's claim in his "Vite" of 1550 that Cosimo was responsible for the handling of the commission has been questioned.
