Frescoes in the Sistine Chapel

Luca Signorelli probably joined the team of the four painters (Perugino, Botticelli, Cosimo Rosselli and Ghirlandaio) who were commissioned by Pope Sixtus IV to decorate the walls of the Sistine Chapel by the suggestion of Perugino. Vasari implies that it was Sixtus IV who summoned Signorelli to work in competition with the other painters in his palace chapel. The fresco containing the last scenes from the life of Moses was attributed by Vasari to Luca Signorelli and Bartolomeo della Gatta. However, the question of authorship of this painting is unsettled.
