Martino di Bartolomeo

From specific aspects of his early style, he is believed to have trained in the studio of Taddeo di Bartolo.

As a young man Martino collaborated with Giovanni di Pietro da Napoli (active 1402-1405) in Pisa.

The fresco cycle in the church of San Giovanni Battista di Cascina, outside Pisa, bears Martino’s signature, and the date 1398.

Martino's early activity as an illuminator of manuscripts is based on Luciano Bellosi's recognition of his hand in the set of choirbooks commissioned for the cathedral of Lucca by its bishop, Niccolò Guinigi, in 1394.

[3] When he contracted with the Collegiata of San Gimignano for the polychromy of the carved wooden Annunciation in 1420, the sculptor, Jacopo della Quercia, stood guarantor.
