Almost thirteen centuries later Philip Labbé, whom we shall learn to know as the first author of a bibliography of bibliographies to be published as a separate work, found St. Jerome's list and after making some additions, put it in alphabetical order. He could not find a proper place for it in his own bibliography of bibliographies, the _Bibliotheca bibliothecarum_ of 1664, and buried it without any apparent reason immediately after a reference to a book by Constantinus Felicius that dealt with Cicero's exile and glorious return. I suspect that the slip containing this information had been misplaced in his manuscript. Labbé wrote as follows: Besides Damastes Sigiaeus,[9] many have written on the lives of scholars, for example, Agatharcides of Cnidus,[10] Amphicrates,[11] Antigonus Carystius, Aristoxenus, Artemon of Magnesia,[12] the Carthaginian Charon,[13] Clearchus of Soli,[14] Hermippus of Smyrna, Satyrus, Timagenes of Miletus,[15] and others, and among Latin writers, Varro, Santra, Nepos, [and] Hyginus, whom St. Jerome cites along with Suetonius on p. 62.[16] Labbé's careless treatment of this information suggests that he had not finished preparing it for publication. The text itself is not entirely intelligible. He did not put it, as St. Jerome had done, in the introduction and failed to find any other logical place for it. St. Jerome's list obviously interested Labbé, for he quoted it again in the article "Sanctus Hieronymus." When Antoine Teissier revised and enlarged the _Bibliotheca bibliothecarum_ in 1686, he came upon this duplication and retained only the passage in the article "Sanctus Hieronymus." Except the long-forgotten Labbé, subsequent bibliographers know nothing of St. Jerome's brief list. It did not set anyone to writing bibliographies of bibliographies, and no example has been reported in the almost uncharted area of bibliographical history that lies between St. Jerome and the Renaissance.
