シエナ大聖堂
According to the Siena Cathedral archives, Nicola Pisano was born to Petrus de Apulia between 1200 and 1205 in the city of Apulia. Nicola may have trained in the Imperial workshops of Holy Roman Emperor Frederick II who encouraged artists towards the "revival of classical forms" where "the representational traditions of classical art were given new life and spiritual force". Frederick favoured the fusion of the classical and Christian traditions.
