Superlative -- masculine accusative singular or neuter nominative/accusative singular -- of the adjective already given as epsilon 2710.
Adler cites for comparison a scholium to Lucian, Dialogues of the Dead 17.1 (259.26 Rabe), which uses the positive form of the gloss to gloss the positive form of the headword (in that instance, both feminine, singular accusative). She also reports that the lemma is found in the lexicon of Codex Laurentianus 59.16.
