McKim employed Roman doric columns based directly on the work of the sixteenth-century Italian architect Giacomo Barozzi da Vignola for the screen separating the cross hall and entrance hall.
Here he worked for Pope Julius III and, after the latter's death, he was taken up by the papal family of the Farnese and worked with Michelangelo, who deeply influenced his style (see Works section for details of his works in this period).
