Lippo Memmi
Memmo di Filippucci had two sons who were painters, Lippo Memmi and Federico Memmi. His son-in-law was Simone Martini, one of the most outstanding and influential painters of Siena. In 1317, Lippo di Memmi received a commission to paint a large Maesta in the main chamber of the Town Hall. It is thought that Memmo assisted his son with this work. Memmo may also have worked with Lippo Memmi on the fresco cycle of the New Testament in the Collegiate Church of San Gimignano, completed around 1345. These frescos have long been ascribed to "Barna of Siena" but are now believed to be the work of Lippo di Memmi and workshop.
