Pietro Cavallini

His Last Judgment in the Church of Santa Cecilia in Trastevere in Rome, painted c. 1293 and considered Cavallini's masterwork, demonstrates an artistic style known as Roman naturalism.

In Florence, the influence of classical Roman forms combined with the Byzantine artistic heritage of the region to spark an interest in volumetric, naturalistic paintings and statuary.

This naturalism is also evident in the Basilica of San Francesco d'Assisi in Assisi, built in the early years of the 13th century in honour of the newly canonized St. Francis.

From 1308 Cavallini worked in Naples at the court of King Charles II of Anjou, notably in the churches of San Domenico Maggiore (1308) and Santa Maria Donnaregina (1317), together with his fellow Roman Filippo Rusuti.

He returned to Rome before 1325, beginning the external decoration of the Basilica di San Paolo fuori le Mura in 1321, with a series of Byzantine-style mosaics.
