 Dante presents the news as a prophecy by the sower of discord, Pier da Medicina, that they, the best of Fano, must beware of Malatestino I Malatesta, tyrant of Rimini, who will kill them by "mazzeratura" (drowning in leaded bags) near Cattolica.The lack of any archive source on such an incident made some Dante commentators even think that here Piero wanted to perpetrate his sin as a sower of discord by putting tares between the two of Fano and the lord of Rimini.But Dante's preciseness has more of a taste of revelation and since it is a serious allegation, it may be that, as in other cases, the power of the persons concerned has covered up any mention in contemporary documents.
