The “Bibliotheca Hispana” has already been referred to more than once in this chapter, and must so often be relied on as an authority hereafter that some notice of its claims should be given before we proceed farther. Its author, Nicolas Antonio, was born at Seville, in 1617. He was educated, first by the care of Francisco Jimenez, a blind teacher, of singular merit, attached to the College of St. Thomas in that city; and afterwards at Salamanca, where he devoted himself with success to the study of history and canon law. When he had completed an honorable career at the University, he returned home, and lived chiefly in the Convent of the Benedictines, where he had been bred, and where an abundant and curious library furnished him with means for study, which he used with eagerness and assiduity. He was not, however, in haste to be known. He published nothing till 1659, when, at the age of forty-two, he printed a Latin treatise on the Punishment of Exile, and, the same year, was appointed to the honorable and important post of General Agent of Philip IV. at Rome. But from this time to the end of his life he was in the public service, and filled places of no little responsibility. In Rome he lived twenty years, collecting about him a library said to have been second in importance only to that of the Vatican, and devoting all his leisure to the studies he loved. At the end of that period, he returned to Madrid, and continued there in honorable employments till his death, which occurred in 1684. He left behind him several works in manuscript, of which his “Censura de Historias Fabulosas”--an examination and exposure of several forged chronicles which had appeared in the preceding century--was first published by Mayans y Siscar, and must be noticed hereafter.
