Diogenianus

Diogenianos Grammatikos (also Diogenian, Greek Διογενειανός, Διογενιανός ) was an ancient Greek grammarian. He came from Heraclea on the Pontus and lived at the time of the Roman emperor Hadrian ( 117-138 AD).

He wrote grammatical and lexical writings that have come down to only mentions and uses by other authors. His main work is all-encompassing dictionary ( Λέξις παντοδαπή ), which is arranged alphabetically and is an excerpt of the work of Pamphilus of Alexandria and Zopyrion. Diogenianos had crowded the work of his predecessors, which included 95 books on 5 books. Also, the dictionary of Julius Vestinus was involved from Diogenianos. A revised version of the dictionary, which is the later lexicographer Hesychius of Alexandria in the proem of his dictionary, Diogenianos issued under the title Περιεργοπένητες. Whether the two works were in fact identical, is unclear. Diogenians dictionary was used until the 12th century in many cases, most commonly in Etymologicum magnum.

Aside from his dictionary authored Diogenianos following headings:

• An anthology of epigrams on rivers, lakes, springs, mountains and cliffs ( ἐπιγραμμάτων ἀνθολόγιον περὶ ποταμῶν λιμνῶν κρηνῶν ὀρῶν ἀκρωρειῶν )
• A brief alphabetical listing of rivers περὶ ποταμῶν κατὰ στοιχεῖον ἐπίτομος ἀναγραφή
• A comprehensive catalog of cities throughout the known world συναγωγὴ καὶ πίναξ τῶν ἐν πάσῃ τῇ γῇ πόλεων
