 Above this panel, in a lunette, is a "Flagellation of Christ" scene, which, with its violent action, twisted but anatomically correct bodies, and volumetric plasticity, shows a familiarity with the progressive Florentine draftsmanship of Pollaiuolo.Work from Matteo's middle period includes an altarpiece dated to 1477 for the oratory of Santa Maria delle Nevi in Siena; the altarpiece of Santa Barbara, dated to 1478-79 for Church of San Domenico, Siena; and what is considered Matteo di Giovanni's masterpiece, the "Massacre of the Innocents", which is signed and dated 1482.During his mature period, Matteo began to paint idyllic and naturalistic landscape scenes employing delicate, lyrical colors derived from the Umbrian school of painting.
