DIOGENIANUS  , of

Heraclea on the Pontus (or in Caria), Greek grammarian, flourished during the reign of Hadrian . He was the author of an alphabetical lexicon, chiefly of poetical words, abridged from the great lexicon (Hope 7Xc000-iav) of Pamphilus of Alexandria (1l . A.D . 5o) and other similar works . It was also known by the title Hepcepyo7rEV17res (for the use of "industrious poor students ") . It formed the basis of the lexicon, or rather glossary, of Hesychius of Alexandria, which is described in the preface as a new edition of the work of Diogenianus . We still possess a collection of proverbs under his name, probably an abridgment of the collection made by himself from his lexicon (ed. by E . Leutsch and F . W . Schneidewin in Paroemiographi Graeci, i . 1839) . Diogenianus was also the author of an Anthology of epigrams, of treatises on rivers, lakes, fountains and promontories; and of a list (with map) of all the towns in the world .
