 Lorenzo's works were usually religious scenes in tempera with gold backgrounds.The exact year of Lorenzo’s birth is unknown, but should be approximately 1374, for the first recorded date of his existence is in 1392 when it is documented that Lorenzo and his mentor, Niccolò di Pietro Gerini, painted frescoes in the church of San Francesco at Pisa.Lorenzo is often erroneously cited as the son of Niccolò di Pietro Gerini because he completed some works with the painter, and Lorenzo's work is stylistically similar to Gerini's.
