GUGLIELMO da PISA. - Sculptor active in Pisa from 1159 to 1162 on the pulpit of the cathedral, later transferred to Cagliari to be replaced by that of Giovanni Pisano.
In this work the various scenes, in which figures are presented wearing garments with fine, closely set parallel folds, skilfully arranged against a background ornamented with decorative motifs, within a clear spatial conception, tend toward pictorial effects of contrasts of light. The sculptor displays connections with Lombard art (and for this reason his origin has been supposed to be Lombard), with Byzantine art, and with Provençal art (sculptures on the façades of St-Gilles and St-Trophime), as well as echoes of that pictorial style also found in Roman sarcophagi of the 4th century. His work was echoed in that of many followers, such as Gruemonte and Biduino, not to mention the numerous anonymous artists who left works in the region.
