Italian painter, a native of Pisa and a pioneer who, coming from Tuscany to Assisi, influenced the development of Umbrian art.

It is said that he painted in the upper church of Assisi, notably a “Crucifixion” dated 1236, with a figure of Father Elias, the general of the Franciscans, embracing the cross, but this painting no longer exists. Three large Crucifixions are ascribed to the same master, whose signature can be traced on them. One is in Santissimo Raineri e Leonardo in Pisa and was formerly in the convent of Santa Anna; another, in the Museo Civico at Pisa, is completely overpainted; and the third is in Santa Maria degli Angeli at Assisi. In these paintings Christ is represented with his head leaning on one side with an expression of pain and his body bending forward in agony—a conception differing from “the triumphant Christ” of the preceding age.
