Focus on Portrait of a Man (Signorelli) and explain the History.
In 1490–1492 Signorelli was in Volterra, a city under Florentine control, under the patronage of the House of Medici. Here he painted an Annunciation, a Virgin Enthroned with Saints, a Circumcision of Christ and, perhaps, this painting, attributed to that period for its stylistic resemblance with those works.
