 That Matteo, at this time, is recorded as having colored and gilded a sculpture of the Archangel Gabriel by the celebrated Sienese sculptor Jacopo della Quercia is a reminder of the sort of tasks performed by an artist in the 15th century.Matteo and Giovanni also collaborated in the embellishment of organ shutters in the Siena Cathedral and in the decoration of the San Bernardino Chapel in that cathedral.That Matteo had succeeded in establishing an artistic reputation is demonstrated by his selection as one of four Sienese painters who were to furnish altarpieces for the chapels of the Pienza Cathedral erected as part of the urban renewal of the town.
