 Left to conjecture, we might imagine him as having been trained in the workshop of sculptor/painter Lorenzo di Pietro, better known as Vecchietta but he clearly was influenced by Stefano di Giovanni, called Sassetta and Domenico di Bartolo.The miniaturist Girolamo da Cremona and the Florentine painter Antonio del Pollaiolo also seemed to have contributed to Matteo's distinctive style.In 1452, Matteo entered into partnership with the painter Giovanni di Pietro, and the two shared living quarters in the San Salvatore neighborhood of Siena in 1453.
