Mantegna was born in 1431. He trained in painting at the Padua School which Donatello and Paolo Uccello had previously attended. Even at a young age commissions for his work flooded in, as for the frescoes of the Ovetari Chapel in Padua. In a short space of time Mantegna found his niche as a modernist due to his highly original ideas, particularly the use of perspective in his works. His marriage with Nicolosia Bellini, the sister of Giovanni, paved the way for his entree into Venice. Mantegna reached an artistic maturity with his altarpiece of San Zeno. He remained in Mantua and became the artist for one of the most prestigious courts in Italy – the Court of Gonzague. Despite his links with Bellini and Leonardo da Vinci, Mantegna refused to adopt their innovative use of colour or leave behind his own technique of engraving. The Camera Picta is considered his most accomplished work.
