The Altar Piece of Corciano is an oil painting on wood. The author is Pietro Vannucci, called “il Perugino”. It was commissioned by Cristoforo Ciacci and Luca di Matteo Baroni for the church of Saint Mary of Corciano. The painting was realized between 1512 and 1513 during the Renaissance. It is divided into two parts: the main table and the altar-step. The first represents the Ascension of the Virgin Mary surrounded by angels, seraphs and cherubs; below it there are the apostles in perspective on a hilly background. On the altar-step there is the depiction of the Annunciation and the Adoration of the Holy Child. The characters are located under an architectural structure within a natural landscape. The altar piece dates back to the late period of Perugino and it was influenced by Leonardo da Vinci's painting. The features that give this altar piece great value are the brightness of the colours, the use of gold, the attention to detail and the grace of the figures.
