old, and he had some years before acquired such a reputation for learning and eloquence that he had been invited from Italy (he was a native of the Duchy of Milan) to the Spanish Court. His letters, as they have come down to us, begin about five years before this,[193] and it is said that just at this time (1493) he began the composition of his Decades. Las Casas has borne testimony to the value of the Decades for a knowledge of Columbus, calling them the most worthy of credit of all the early writings, since Martyr got, as he says, his accounts directly from the Admiral, with whom he often talked. Similar testimony is given to their credibleness by Carbajal, Gomez, Vergara, and other contemporaries.[194] Beginning with Muñoz, there has been a tendency of late years to discredit Martyr, arising from the confusion and even negligence sometimes discernible in what he says. Navarrete was inclined to this derogatory estimate. Hallam[195] goes so far as to think him open to grave suspicion of negligent and palpable imposture, antedating his letters to appear prophetic. On the other hand, Prescott[196] contends for his veracity, and trusts his intimate familiarity with the scenes he describes. Helps interprets the disorder of his writings as a merit, because it is a reflection of his unconnected thoughts and feelings on the very day on which he recorded any transactions.[197] What is thought to be the earliest mention in print of the new discoveries occurs in a book published at Seville in 1493.—_Los tratados del Doctor Alonso Ortiz_. The reference is brief, and is on the reverse of the 43d folio.[198] Not far from the same time the Bishop of Carthagena, Bernardin de Carvajal, then the Spanish ambassador to the Pope, delivered an oration in Rome, June 19, 1493, in which he made reference to the late discovery of unknown lands towards the Indies.[199] These references are all scant; and, so far as we know from the records preserved to us, the great event of the age made as yet no impression on the public mind demanding any considerable recognition. =D.= SECOND VOYAGE (_Sept._ 25, 1493, _to June_ 11, 1496).—First among the authorities is the narrative of Dr. Chanca, the physician of the Expedition. The oldest record of it is a manuscript of the middle of the sixteenth century, in the Real Academia de la Historia at Madrid. From this Navarrete printed it for the first time,[200] under the title of “Segundo Viage de Cristobal Colon,” in his _Coleccion_, i. 198.
