Vecchietta
Francesco di Giorgio e di Lorenzo (1410 – June 6, 1480), known as Vecchietta or Lorenzo di Pietro, was an Italian Sienese School painter, sculptor, goldsmith and architect of the Renaissance. He is among the artists profiled in Vasari's Le Vite delle più eccellenti pittori, scultori, ed architettori.
It is believed Vecchietta was a pupil of Sassetta, Taddeo di Bartolo and Jacopo della Quercia. Later in his life he was the master of Francesco di Giorgio and Neroccio de’ Landi.
"Pittor dello Spedale"
Vecchietta was born in Castiglione d'Orcia, and lived in Siena. Much of his work may be found there, particularly at the Hospital of Santa Maria della Scala, lending him yet another name: pittor dello spedale (or "painter of the hospital").
For the Pellegrinaio (Pilgrim Hall) at the Hospital complex, Vecchietta painted a series of frescoes, along with Domenico di Bartolo and Priamo della Quercia, including The Founding of the Spedale and The Vision of Santa Sorore, depicting a dream of the mother of the cobbler Sorore, the mythical founder of the Hospital.
