of his work on the doors is submerged, like that of the other assistants, in the force of Ghiberti's design and personality." From this, Michelozzo learned how to run a closely supervised shop, how to organize it efficiently, how to train and control assistants, and how to deal shrewdly in business and financial affairs. "He was exposed to Ghiberti's use of antique motifs, he absorbed Ghiberti's ability in juxtaposing antique and Gothic elements, and he was undoubtedly influenced by Ghiberti's style and artistic concepts." While working under Ghiberti, Michelozzo created the statue of the young St. John over the door of the Duomo in Florence, opposite the Baptistery, along with the silver statuette of John the Baptist on the altar-frontal of San Giovanni. Under Donatello, Michelozzo assisted in the building of the sacristy of Santa Trinita, where "Ghiberti [had] started to fuse together late-Gothic and antique forms." Both Donatello and Michelozzo began as sculptors with an uncompromising dedication to antiquity, and this was evident when Donatello enlisted Michelozzo's help in the decoration of the tabernacle of St. Louis of Toulouse. Michelozzo also became the partner responsible for the architectural frames of Donatello's sculptures such as the funerary monument of Antipope John XXIII. In 1428, together with Donatello, Michelozzo erected an open-air pulpit at an angle of the Cathedral of St. Stephen at Prato, designed for the regular public displays of their famous relic, the Girdle of Thomas (Sacra Cintola). Though Donatello is the more well-known of the two, "it would be a mistake to underrate Michelozzo's share in the work, for where Donatello appears as the sole designer of architectural ornament his style is quite different. He completely subordinates the architectural setting to his sculpture and makes architecture, so to speak, its handmaid. The beautiful ornamental sculpture in Brunelleschi's Sagrestia Vecchia shows how far Donatello would go with his sculpture in order to provide it with an effective frame in the extraordinarily vigorous modelling of the broad, slanting surrounds of his overdoors and medallions." Influences and Patronage Cosimo dei Medici Few historians have disputed Cosimo's close relationship to Michelozzo, who was the Medici architect for nearly forty years. "Michelozzo was more agreeable and accessible to the advice and desires of Cosimo than the turbulent Brunelleschi, and was willing to follow the strong personal tastes of his patron." Their relationship was best described by Angelo Fabroni in 1789, who said: "Cosimo
