His good friend was very unwell, but received him with joy, and pressed him to pass the night under his roof.

That night and all the next day it rained so heavily that Petrarch, more from fear of his books and papers being damaged than from anxiety about his own health, gave up his Italian journey for the present, and, returning to Vaucluse, spent there the rest of November and the whole of December, 1352.
Early in December, Petrarch heard of the death of Clement VI., and this event gave him occasion for more epistles, both against the Roman court and his enemies, the physicians.

Clement's death was ascribed to different causes.

Petrarch, of course, imputed it to his doctors.
Villani's opinion is the most probable, that he died of a protracted fever.

He was buried with great pomp in the church of Notre Dame at Avignon; but his remains, after some time, were removed to the abbey of Chaise Dieu, in Auvergne, where his tomb was violated by the Huguenots in 1562.
