Early documents indicate that some of Cecco di Pietro's first work as an artist was restoring frescoes. He is first mentioned in notices from around 1370 as having worked at the
Campo Santo with five other painters working on restoring frescoes in the area. He is next mentioned in notices from 1372 concerning the restoration of the
Story of Job fresco in the
Campo Santo with
Francesco Volterra. Records regarding his pay from the time show that it was a small sum of money when compared with other artists of the day, indicating that he was still inexperienced and learning the craft of the Pisan school from
Volterra. Following the restoration of the
Story of Job, there is another notice of Cecco di Pietro being hired in 1379 to restore the
Inferno from a trio of frescoes by
Buonamico Buffalmacco which were also located in the
Campo Santo and were apparently damaged by some untrained apprentices in a previous restoration attempt. Of the restoration of the
Inferno, most scholars only attribute the 2nd circle of Hell and two figures to the side of the Devil as the portions restored by Cecco, with the other restoration work carried out by a separate, unknown artist. One of his masterpieces is the
Madonna and Child, signed and dated 1378, now at the Statens Museum for Kunst in
Copenhagen in Denmark, which was the central compartment of Saint
Rainerius polyptych made for the church of San Francesco in
Pisa. Cecco continued to receive a number of local commissions, painting many altarpieces. One such altarpiece is the
Polyptych of Agnano, executed between 1386–1395 for the church and convent at
Agnano, and is considered one of Cecco's most important pieces. He continued to work in the fresco style until his death around 1402 == Style ==
