Ticknor lays it down that "no suspicion seems to have been whispered, either at the moment of their first publication, or for a long time afterwards," of the correctness of this attribution; and he implies that the first doubter was Luis José Velázquez, Marqués de Valdeflores, who, when he reprinted the book in 1753, started the theory that the poems were Quevedo's own. This is not so. Quevedo's mistake was pointed out by Manuel de Faria y Sousa in his commentary to the _Lusiadas_, printed at Madrid in 1639. That Quevedo should make a Bachelor of a man who had no university degree, that he should call the writer of the _Visión deleitable_ Francisco when in truth his name was Alfonso, were trifles: that he should antedate his author by nearly two centuries—this was a serious matter, and Faria y Sousa took pains to make him realise it. It must have added to the editor's chagrin to learn that Torre had been friendly with Lope de Vega, who could have given accurate information about him; but Lope and Quevedo were not on speaking terms, owing to the mischief-making of the former's parasite, Pérez de Montalbán. Quevedo had made no approach to Lope; Lope saw the blunder, smiled, and said nothing in public. Through Pérez de Montalbán the facts reached Faria y Sousa, who exulted over a mistake which was, indeed, unpardonable. The discomfiture was complete: for the first and last time in his life Quevedo was dumb before an enemy. Meanwhile, Velázquez' theory has found some favour with López Sedano and with many foreign critics: as, for example, Ticknor.
