The Cortona Altarpiece, the Annunciation (1433!!) , was executed for the church of San Domenico in Cortona.

Undoubtedly Angelico's first truly great painting, it's absolutely majestic.The small scenes painted in translucent colors at the base of the Altarpiece are each in themselves small hymns of praise to the Virgin. A small section in the panel of Mary's Visit to Elizabeth made art history. It is the first identifiable landscape in Italian painting, a view of Lake Trasimeno as seen from Cortona. Incredible use of perspective and such a beautiful harmonious colours. A true masterpiece
