Lippo Memmi
 
   
Lippo Memmi (c. 1291 – 1356) was an Italian painter from Siena. He was the foremost follower of Simone Martini, who was his brother-in-law.

Together with Martini, in 1333 he painted one of the masterworks of the International Gothic, the Annunciation for the Sienese church of Sant'Ansano (now in the Uffizi). He was one of the artists who worked at the Orvieto Cathedral, for which he finished the Madonna dei Raccomandati. Later he followed Martini at the Papal court in Avignon, where he worked until the mid-14th century.

After his return to Siena Memmi executed several works until his death in 1356.
 
   
 
The Chapel of the Corporal is situated at the end of the left aisle of the Cathedral. It was built in 1350-61 for the reliquiary keeping the sacred cloth of the miracle of Bolsena. Memmi's fresco is also in this chapel. The painting was variously modified, specially in the 19th century. Some think that the only original part of the painting is the lower one, where we can see the Pious Women and the Brethren recommending themselves to the Madonna in prayer.
