" The leader of Christendom, Pope Clement VI, was preserved in health by this method, though for an unrecognized reason: Clement’s doctor, Guy de Chauliac, ordered that two huge fires should burn in the papal apartments and required the Pope to sit between them in the heat of the Avignon summer. This drastic treatment worked, doubtless because it discouraged the attention of fleas and also because de Chauliac required the Pope to remain isolated in his chambers. Their lovely murals of gardens, hunting, and other secular joys, painted at Clement’s command, perhaps gave him some refreshment. A Pope of prodigal splendor and “sensual vices,” Clement was also a man of great learning and a patron of arts and science who now encouraged dissections of the dead “in order that the origins of this disease might be known.
