The French Colombos.
There was a Gascon-French subject of Louis XI., Guillaume de Casanove, sometimes called Coulomp, Coullon, Colon, in the Italian accounts Colombo, and Latinized as Columbus, who is said to have commanded a fleet of seven sail, which, in October, 1474, captured two galleys belonging to Ferdinand, king of Sicily. When Leibnitz published, for the first time, some of the diplomatic correspondence which ensued, he interjected the fore-name Christophorus in the references to the Columbus of this narrative. This was in his Codex Juris Gentium Diplomaticus, published at Hannover in 1693. Leibnitz was soon undeceived by Nicolas Thoynard, who explained that the corsair in question was Guillaume de Casanove, vice-admiral of France, and Leibnitz disavowed the imputation upon the Genoese navigator in a subsequent volume. Though there is some difference of opinion respecting the identity of Casanove and the capturer of the galleys, there can no longer be any doubt, in the light of pertinent investigations, that the French Colombos were of no immediate kin to the family of Genoa and Savona, as is abundantly set forth by Harrisse in his Les Colombo de France et d'Italie (Paris, 1874). Since the French Coullon, or Coulomp, was sometimes in the waters neighboring to Genoa, it is not unlikely that some confusion may arise in separating the Italian from the French Colombos; and it has been pointed out that a certain entry of wreckage in the registry of Genoa, which Spotorno associates with Christopher Columbus, may more probably be connected with this Gascon navigator.
Bossi, the earliest biographer in recent times, considers that a Colombo named in a letter to the Duke of Milan as being in a naval fight off Cyprus, between Genoese and Venetian vessels, in 1476, was the discoverer of the New World. Harrisse, in his Les Colombo, has printed this letter, and from it it does not appear that the commander of the Genoese fleet is known by name, and that the only mention of a Colombo is that a fleet commanded by one of that name was somewhere encountered. There is no indication, however, that this commander was Christopher Columbus. The presumption is that he was the roving Casanove.
Leibnitz was doubtless misled by the assertion of the Historie of 1571, which allows that Christopher Columbus had sailed under the orders of an admiral of his name and family, and, particularly, was in that naval combat off Lisbon, when, his vessel getting on fire, he swam with the aid of an oar to the Portuguese shore. The doubtful character of this episode will be considered later; but it is more to the purpose here that this same book, in citing a letter, of which we are supposed to have the complete text as preserved by Columbus himself, makes Columbus say that he was not the only admiral which his family had produced. This is a clear reference, it is supposed, to this vice-admiral of France. It is enough to say that the genuine text of this letter to the nurse of Don Juan does not contain this controverted passage, and the defenders of the truth of the Historie, like D'Avezac, are forced to imagine there must have been another letter, not now known.
The younger French admiral.
Beside the elder admiral of France, the name of Colombo Junior belonged to another of these French sea-rovers in the fifteenth century, who has been held to be a nephew, or at least a relative, of the elder. He has also sometimes been confounded with the Genoese Columbus.
Genealogy.
Pretenders.
To determine the exact relationship between the various French and Italian Colombos and Coulons of the fifteenth century would be hazardous. It is enough to say that no evidence that stands a critical test remains to connect these famous mariners with the line of Christopher Columbus. The genealogical tables which Spotorno presents, upon which Caleb Cushing enlightened American readers at the time in the North American Review, and in which the French family is made to issue from an alleged great-grandfather of Christopher Columbus, are affirmed by Harrisse, with much reason, to have been made up not far from 1583, to support the claims of Bernardo and Baldassare (Balthazar) Colombo, as pretenders to the rights and titles of the discoverer of the New World.
