Nicola Pisano
In 1264 Nicola Pisano was aksed to work on a grand shrine in memory of St Dominic, called the Arca di San Domenico in the Basilica of San Domenico in Bologna. It is believed that Nicola made the main design but many other sculptors worked on it. More than 200 years later, it was still not finished, and Michelangelo, when he was still a teenager, made three small statues for it.
