The Arca di San Domenico is the marble tomb of Saint Dominic, founder of the Dominican order, in the Basilica of San Domenico in Bologna. Sculptors worked on it for almost five centuries, from Nicola Pisano's workshop in the 1260s to the 18th-century altar below. Its most famous pieces are three small figures carved in 1494–95 by a 19-year-old Michelangelo.

Five centuries of work on one tomb
Saint Dominic died in Bologna on 6 August 1221 and was buried behind the altar of the small church of San Nicolò delle Vigne, which the friars soon enlarged into today's basilica. In 1233 his remains were moved to a simple marble sarcophagus on the floor, but the crowds of pilgrims made it hard to see. So in 1264 the Dominicans commissioned Nicola Pisano, already famous for his pulpit in Pisa, to make a grander tomb. Pisano designed it, but left for Siena in 1265, and his workshop, led by Lapo di Ricevuto and with the young Arnolfo di Cambio, finished the carving by 1267. The sarcophagus once stood on statue supports; these were later removed and are now scattered among museums in London, Paris, Florence and Boston.
In 1469 Niccolò da Bari was asked to add a crowning on top. He worked on it on and off for the rest of his life and became known as Niccolò dell'Arca, after the tomb, but when he died in 1494 several figures were still missing. That year the young Michelangelo had arrived in Bologna from Florence, and he carved Saint Petronius, Saint Proculus and a kneeling angel holding a candlestick. Later additions followed: Alfonso Lombardi carved a step in 1532, the chapel was rebuilt from 1597, and in the 18th century the whole tomb was set on a marble altar.
What to look for
- The front of the sarcophagus: Dominic bringing back to life the young Napoleone Orsini after a fall from his horse, and his books surviving a fire while those of his opponents burn.
- The two kneeling angels with candlesticks on the altar: the left one is by Niccolò dell'Arca, the right one by Michelangelo. Compare the delicate first with the solid, muscular second.
- Saint Proculus, by Michelangelo, at the back of the tomb: a frowning young man with a cloak over his shoulder, often compared with his David, made about ten years later.
- Saint Petronius, Bologna's patron saint, holding a model of the city; Niccolò began it and Michelangelo finished it.
- The crowning: God the Father on top of a candelabrum, with putti, dolphins and garlands of fruit, above the four Evangelists.
- Guido Reni's fresco of the Glory of Saint Dominic in the dome of the chapel, painted in 1613–15.
Where is Dominic now?
The saint's remains lie in a cypress coffin inside the sarcophagus, with one exception: his head is kept apart, in a gilded reliquary made by Jacopo Roseto da Bologna in 1383, in a small space behind the tomb. Under the arch of the chapel you are therefore standing at the burial place of one of the most influential religious figures of the Middle Ages.
Tips for your visit
- Avoid Mass times: the chapel is used for worship, and visitors are asked to keep quiet and dress respectfully.
- Walk around the tomb as far as you are allowed: Saint Proculus and some of the best reliefs are on the back and sides.
- Spend a minute outside in Piazza San Domenico, with its raised medieval tombs, before or after your visit.
