ANTONIO, NICOLAS (1617-1684), Spanish bibliographer, was born at Seville on July 31, 1617, and died at Madrid in the spring of 1684. His Bibliotheca Hispana nova, dealing with the works of Spanish authors who flourished after appeared in Rome in 1672 ; the Bibliotheca Hispana vetus, a literary history of Spain from the time of Augustus to the end of the 15th century, was revised by Manuel Marti and published by Antonio's friend, Cardinal Jose Saenz de Aguirre in Rome in 1696. A fine edition of both parts, with additional matter found in Antonio's manuscripts, and with supplementary notes by Francisco Perez Bayer was issued in Madrid in 1787-88. This great work, incomparably superior to any previous bibliography, is still unsuperseded and indispensable.
Of Antonio's miscellaneous writings the most important is the posthumous Censure de histories fabulosas (Valencia, 1742), in which erudition is combined with critical insight. His Bibliotheca Hispana rabinica has not been printed ; the manuscript is in the national library at Madrid.
