Giovanni di Paolo was influenced by many great artists in trecento and quattrocento Italy. By the mid-century, when the Florentine quattrocento was fully mature, Venice still lagged well behind. Inspired by the quattrocento, Fein paints in egg tempera, which she makes herself. These quattrocento balustrades are likely to be following yet-unidentified Gothic precedents. This became an integral part of Quattrocento art. The two-story quattrocento cloister remained unchanged by the addition of the library. His work stems from traditional Quattrocento painting. It was described as equal in glory to the Italian Quattrocento. Its realism has been described as unique among the portraits of the Quattrocento. The putto disappeared during the Middle Ages and was revived during the Quattrocento. In the "Quattrocento", concepts of architectural order were explored and rules were formulated. That same year, Benozzo returned to his native city Florence, the epicenter of "Quattrocento" art. Fesch was a fairly early collector of Quattrocento paintings, or "Italian Primitives". The rich and various colours may have influenced the great Venetian painters of the Quattrocento. The leading architects of the Early Renaissance or Quattrocento were Brunelleschi, Michelozzo and Alberti.
