The end period of the Early Renaissance in Italian art is marked, like its beginning, by a particular commission that drew artists together, this time in cooperation rather than competition. Pope Sixtus IV had rebuilt the Papal Chapel, named the Sistine Chapel in his honour, and commissioned a group of artists, Sandro Botticelli, Pietro Perugino, Domenico Ghirlandaio and Cosimo Rosselli to decorate its wall with fresco cycles depicting the Life of Christ and the Life of Moses. In the sixteen large paintings, the artists, although each working in his individual style, agreed on principles of format, and utilised the techniques of lighting, linear and atmospheric perspective, anatomy, foreshortening and characterisation that had been carried to a high point in the large Florentine studios of Ghiberti, Verrocchio, Ghirlandaio and Perugino.
