Between 1415 and 1420, Pisanello was the assistant of the renowned painter and illuminator Gentile da Fabriano from whom he acquired his refined, delicate, detailed style. Pisanello also acquired from him a taste for precious materials and beautiful fabrics that can be found in his later paintings. The frescoes in the Doge's Palace at Venice, on which they worked together, have perished as well as the frescoes in the Basilica of St. John Lateran and the palaces of Mantua and Pavia.
