The unglossed primary headword is a feminine noun in the nominative (and vocative) singular; see LSJ s.v.; ps.-Herodian, Partitiones 93.g; and cf. generally nu 533, nu 534, nu 535, and nu 537. Adler also cites the unpublished Ambrosian Lexicon (419).
[1] For this secondary lemma see LSJ s.v. nwqro/s, -a/, -o/n. Its gloss is a two-ending adjective in the masculine (and feminine) nominative singular; LSJ s.v. a)sqenh/s, -e/s. Identical glossing in Photius' Lexicon (nu308 Theodoridis) and the Synagoge; cf. Hesychius s.v. gloio/s. Adler also cites Boysen's Lexicon Seguerianum.
[2] As Adler notes, this quotation was attributed to Polybius by 'Wesseling' [= the Westphalian scholar Peter Wesseling (1692-1764)]. Indeed, Polybius 30.18.2 (web address 1) attaches a similar description to the servile behavior of Pr(o)usias II (king [182-149] of Bithynia, in northwest Asia Minor, present-day Turkey; Barrington Atlas map 52 grids E4-G3) when he appeared (167-6) before the Roman senate; cf. pi 2913 and pi 2914; OCD(4) s.v. Prusias(2); and Walbank, p. 441. A positive identification of the fragment, however, remains elusive.
