[177] In another letter of the same date the Emperor complains to the King of Portugal that the latter's ambassadors have not been willing to abide by the treaty of Tordesillas in their conferences with the Castilian plenipotentiaries, "although our right to those regions discovered and taken possession of by our fleet is fully apparent from the treaties and compacts negotiated over the division of lands and the line of demarcation, and confirmed in the name of each one of us." Neither would they discuss the new propositions submitted to them--"although with some prejudice to our right;" nor would they themselves submit new propositions; consequently they are returning to Portugal without reaching any decision. The letter closes by saying that the Emperor is about to write about the whole affair to his representative, "Juan de Zúñiga, knight of the order of Santiago, residing there [at Lisbon] in our behalf;" and King João is earnestly requested to rest assured of the love and affection of the Spanish monarch. [178] This was an ancient office in the royal house of Castile. [179] Bartulo was an Italian jurisconsult, born (1313) at Sasso-Ferrato, in Umbria; he died at Perusa in 1356. He was entrusted with several important political commissions and wrote upon various points of civil law; some of his works were used as text books in the most famous universities. He has been styled "the first and most thorough of the interpreters of law." Baldo is evidently one of the two brothers Pietro and Angelo Baldo de Ubaldis, both eminent Italian jurisconsults. The former was born at Perusa, in 1324, and died at Pavia, April 28, 1406. He was a man of vast erudition, and held many important posts--his influence extending so far that Charles VI of France implored his aid at the Roman court for convening a general council. He was the author of a number of commentaries and other works. Angelo was born in 1328, and died in 1407; he was (at the same time with his brother) professor of civil law at Perusa, and wrote several commentaries and monographs.

[181] The matter in brackets in these proceedings is evidently notes made by Muñoz, although they may have been made by the Castilian secretary. [182] The number acting for Portugal was not greater than for Spain, as Gomara points out and whom Herrera copies, but the same on either side, only while Portugal had two attorneys, Spain had one attorney and one advocate.--_Navarrete_. [183] This date should be June 7, 1494. The Spanish letter of authorization was dated June 5. [184] Original in handwriting of Don Hernando Colon. (Navarrete, tomo iv, no. xxvii, pp. 343-355.
