There is a statue of St Bruno of Cologne (1035-1101), founder of the Carthusians. It was made by Jean Antoine Houdon between 1766 and 1768. The saint is depicted with his habit, his arms folded and his head bowed in reflective pose. Pope Clement XIV is reputed to have said that the statue was so lifelike that it would have spoken if the order had not forbidden it (the Carthusians take a vow of silence). His head is bowed in humility and thoughtfulness, and the statue is placed so that the saint is turned towards the centre of the apse.
