Besides the Lives of Eugenius IV. (Rerum Italic. tom. iii. P. i. p. 869, and tom. xxv. p. 256), the Diaries of Paul Petroni and Stephen Infessura are the best original evidence for the revolt of the Romans against Eugenius IV. The former, who lived at the time and on the spot, speaks the language of a citizen, equally afraid of priestly and popular tyranny.
