Focus on Tezi Altarpiece and explain the Style.
The panel shows the Madonna and Child on a cloud in the sky, flanked by St. Nicholas of Tolentino and Bernardino of Siena. Below, over a wood landscape, are the traditional depictions of  St. Jerome with the lion, and St. Sebastian struck by arrows. At the bottom, in the middle, is a tabernacle opening which once housed the Holy Sacrament. 
The Madonna is taken from the same cartoon used by Perugino for the Madonna of the Consolation, from the same period. Also, the use of colors is not typical of Perugino, and the work was perhaps executed mostly by his workshop, with the master adding just some touches.
