"In September, 1514, a Venetian diarist and historian, Marino Sanuto wrote in his diary:
‘Si dize eiiam che il re d’Ingaltera, voi lassar la moglie che rha, fia del re di Spagna, qual fo moglie di suo fra- delo, per non poter haver con lei alcuna heredità, e voi tuor per moglie una fia dil ducha di Barbon francese."
Roughly translated:" It is said that the king of England will leave the wife he has, who is the daughter of the king of Spain, as the wife of his brother, for not being able to have any heir with her, and will marry a daughter of the French Duke of Bourbon."
