His nephew Diego succeeded to the rights, silencing those of the daughter of Don Luis by marrying her. They had no issue; and on his death, in 1578, various claimants brought suit for the succession (as shown in the table), which was finally given, in 1608, to the grandson of Isabella, the granddaughter of Columbus. This suit led to the accumulation of a large amount of documentary evidence, which was printed.[362] The vexations did not end here, the Duke of Berwick still contesting; but a decision in 1790 confirmed the title in the present line. The revolt of the Spanish colonies threatened to deprive the Duke of Veraguas of his income; but the Spanish Government made it good by charging it upon the revenues of Cuba and Porto Rico, the source of the present Duke’s support.[363] POSTSCRIPT. After the foregoing chapter had been completed, there came to hand the first volume of _Christophe Colomb, son origine, sa vie, ses voyages, sa famille, et ses descendants, d’après des documents inédits tirés des Archives de Gênes, de Savone, de Séville, et de Madrid, études d’histoire critique par Henry Harrisse_, Paris, 1884. The book is essentially a reversal of many long-established views regarding the career of Columbus. The new biographer, as has been shown, is not bound by any respect for the Life of the Admiral which for three hundred years has been associated with the name of Ferdinand Columbus. The grounds of his discredit of that book are again asserted; and he considers the story as given in Las Casas as much more likely to represent the prototype both of the _Historia general_ of this last writer and of the _Historie_ of 1571, than the mongrel production which he imagines this Italian text of Ulloa to be, and which he accounts utterly unworthy of credit by reason of the sensational perversions and additions with which it is alloyed by some irresponsible editor. This revolutionary spirit makes the critic acute, and sustains him in laborious search; but it is one which seems sometimes to imperil his judgment. He does not at times hesitate to involve Las Casas himself in the same condemnation for the use which, if we understand him, Las Casas may be supposed, equally with the author or editor of the _Historie_, to have made of their common prototype. That any received incident in Columbus’ career is only traceable to the _Historie_ is sufficient, with our critic, to assign it to the category of fiction. This new Life adds to our knowledge from many sources; and such points as have been omitted or slightly developed in the preceding chapter, or are at variance with the accepted views upon which that chapter has been based, it may be well briefly to mention.
