Francesco di Bartolommeo Alfei

Francesco di Bartolommeo Alfei (Montalcino, 1421 - Siena, after 1491) was an Italian painter of the Renaissance, active in Siena. Like other Sienese painters, and different from the contemporary Florentine style, Alfei maintained a gothic and mystical style of painting.
Biography.
Like many of lesser painters of the era, there is much confusion around his life and attributed works. There is in fact, no work known to be by his hand with documentary assurance. He was for many years only known as a name, but in the late 1940s, the art critic Roberto Longhi began to question the attribution of a large predella from the Basilica dell'Osservanza in Siena. Initially the predella had been attributed to Sassetta or Sano di Pietro (by Cesare Brandi). In 2010, documents were found to argue for Sani di Pietro as the Master of the Osservanza Triptych.
Of the documents relating to Alfei are that:
Additionally, in 1464, along with the painter, Sano di Pietro, he asks for payment for work done for the artist Antonio di Simone, to aid in completion of some paintings for Pietro Trecerchi.
Other sources say he had a studio in Siena in "Compagnia di Rialto e Cartagine". He worked for Pope Pius II in 1460, for the diplomat Leonardo Benvoglienti, for the Ottieri della Ciaia family and for Sinolfo di Castellottieri. In 1455 the magistrates of Siena paid Alfei for work at Monte Argentario near Orbetello; works till recently attributed to Ambrogio Lorenzetti and to Sassetta. In 1473 he may have worked in the Marche region for the papal legate, Cardinal Bartolomeo Roverella.
Among works attributed to Alessi are:
Another Bartolomeo Alfei (Macerata, 1460 - Ancona, 1557) was an Italian writer.
