Note 281 — THE SIXTH STORY
John Payne translation
Gianni (Giovanni) di Procida was a Sicilian noble, to whose efforts in stirring up the island to revolt against Charles of Anjou was mainly due the popular rising known as the Sicilian Vespers (a.d. 1283) which expelled the French usurper from Sicily and transferred the crown to the house of Arragon. The Frederick (a.d. 1296-1337) named in the text was the fourth prince of the latter dynasty.
