Letters. 11 Jan 1513. Ferdinand King of Aragon (age 60) to Pedro De UREA, his Ambassador at the Imperial Court.

Shows that the treaty which the Cardinal of Gurk (age 45) has, with the consent of Urea and Vich, concluded at Rome, by excluding the Venetians, undoes all that has been done against France. Henceforth they must make no binding declaration without consulting Ferdinand. Had the English followed his plan they would now be masters of Guienne; and, like them, the Emperor has now hindered the accomplishment of his own wishes and made France stronger. Takes this as a command from God for Christian princes to unite in reforming the Church, and has therefore devised the measures explained in instructions sent by Beltrian. Gurk is to be shown the instructions, but not this letter. If the King of France (age 50) offers Madame Renée (age 2) as security, or offers to put fortresses in trust of third persons, Urea shall point out to the Emperor how little these offers are to be trusted. The marriage of Prince Charles (age 12) with the King of England's (age 21) sister (age 16) must not be broken off; or France will gain the King of England (age 21), to the detriment of Spain and the House of Burgundy. Another essential condition is that all acts of the schismatical Council be annulled. Is glad to hear of the meeting between the Emperor and the King of England, whose alliance is both the guarantee that France will keep peace if concluded and the most valuable support in case of war.

Letters. 13 Jan 1513. Richard Jerningham to Henry VIII. Betwixt this and Candlemas trusts to despatch his business here and next day to leave Milan for Ysbrokk. Has been able to raise only 500 Almain rivets. Jerome Fryskeball's factor and John Antoyn de Lumbard had bought all they could get before Jerningham arrived. The Spaniards do the same. The Duke raises 500 spears. Has made a bargain at Milan for 5,000 rivets. Will thus save his Grace 1,£000 under the price they could be had at in England. Had written of the Duke's entry into Milan. 29 Dec. He was accompanied by the Cardinal of the Swiss [of Sion], the Bishop of Gurk (age 45), the Viceroy of Spain, and the Swiss ambassadors. The last had promised that the keys should be delivered to him in the name of the Pope, and Emperor, the King of Aragon and the Swiss; but the Swiss would not consent. After much dispute that honor was reserved for the Swiss. The castles of Milan, Crema, and Genoa hold to the French. The Spaniards took on the 5th, from the Baron of Byarne, the castle of Trasse. The great and increasing army of the Venetians is mistrusted here, as it is rumoured that the French King and Venetians have made an agreement. Spoke with the Duke and the Viceroy, who say this rumour is not yet con-confirmed. Milan, 13 Jan.
