Cantarella was a poison allegedly used by the Borgias during the papacy of Pope Alexander VI. It may have been identical with arsenic, sprinkled on food or in wine, in the shape of "a white powder with a pleasant taste". If it did exist, it left no trace in the works of contemporary writers. The use of this poison is not well documented in any of the papal records and it was most likely conceived after 1503 as part of Pope Julius II's effort to remove his name from the records.
