Henry William Carless Davis, 1911 Encyclopædia Britannica, Volume 21… (1911)
“ Peter died in 1238, and was buried at Winchester. He was undoubtedly a man of a winning personality, a good diplomat and financier, a statesman whose unpopularity was due in some measure to his freedom from the insularity of the Englishmen, against whom he matched himself. But his name is associated with a worthless clique of favourites, and with the first steps which were taken by Henry III. to establish a feeble and corrupt autocracy. ”
