Arnolfo di Cambio

Arnolfo di Cambio (c. 1240 – 1300/1310 ) was an Italian architect and sculptor of the Duecento, who began as a lead assistant to Nicola Pisano. He is documented as being capomaestro or Head of Works for Florence Cathedral in 1300, and designed the sixth city wall around Florence (1284–1333).

By the end of his career he evidently had one or more workshops of some size, producing work with considerable stylistic variation, and distinguishing his personal hand can be difficult.

Biography
Arnolfo's biography is complicated by lingering uncertainties as to whether "Arnolfo di Cambio", born in Colle Val d'Elsa, Tuscany, and later Master of Works for Florence Cathedral, is the same person as "Arnolfus" who signed the ciboria of San Paolo fuori le Mura and Santa Cecilia in Trastevere in Rome, not to mention "Arnolfus Architectus" who signed the tomb of Pope Boniface VIII. The majority view is that they are the same man, and variations in style are caused by the use of workshop assistants, which many of his large works would certainly have needed. He probably had a workshop in Rome by 1277.

He was Nicola Pisano’s chief assistant on the marble Siena Cathedral Pulpit for the Duomo in Siena Cathedral (1265–1268), but he soon began to work independently on an important tomb sculpture. In 1266–1267 he worked in Rome for King Charles I of Anjou, King of Sicily, portraying him in the famous statue housed in the Campidoglio. He signed the wall tomb of Cardinal Guillaume de Braye (d. 1282) in the church of San Domenico in Orvieto, including an enthroned Madonna (a Maestà) for which he took as a model an ancient Roman statue of the goddess Abundantia; the Madonna's tiara and jewels reproduce antique models.

In Rome Arnolfo had seen the Cosmatesque art, and its influence can be seen in the intarsia and polychrome glass decorations in the Basilica of Saint Paul Outside the Walls and the church Santa Cecilia in Trastevere, where he worked in 1285 and 1293 respectively. In this period he also worked on the presepio of Santa Maria Maggiore, on Santa Maria in Aracoeli, and on the monument of Pope Boniface VIII (1300).

The bronze statue of St. Peter in St. Peter's Basilica is traditionally attributed to him, but this is often doubted. .

In 1294–1295 he worked in Florence, mainly as an architect. According to his biographer Giorgio Vasari, he was in charge of construction of the cathedral of the city, for which he provided the statues once decorating the lower part of the façade destroyed in 1589. The surviving statues are now in the Museum of the Cathedral. While the design of the Church of Santa Croce has been attributed to Arnolfo, this is highly disputed. Vasari also attributed to him the urban plan of the new city of San Giovanni Valdarno.

The monumental character of Arnolfo's work has left its mark on the appearance of Florence. His funerary monuments became the model for Gothic funerary art.

Giorgio Vasari included a biography of Arnolfo in his Lives of the Most Excellent Painters, Sculptors, and Architects.

Dante Alighieri probably makes a discrete reference to him with a double citation of the Battle at Colle Val d'Elsa, birthplace of the great artist, in the year 1269 in the Cantos XI, XIII of Purgatorio. Dante almost certainly met Arnolfo, as architect of the cathedral in Florence, at latest when Dante was prior of Florence in 1300.
