[1] The definition comes from scholion D to Homer, Iliad 1.303 (cf. 9.6). See also Apollonius' Homeric Lexicon (97.27) and Etymologicum Magnum 501.44; cf. Hesychius' odd melano/n at kappa2135 (linked with the Homeric passage by Latte but perhaps [RD] of the black ink in the epigram cited here; cf. LSJ at web address 1). The Homeric scholiast is defining the use of the adjective (also at kappa 1286; cf. kappa 1287, kappa 1288) in the neuter with ai(=ma 'blood'. The use of the two adjectives for black, understandable with clotted blood, has caused some question when applied to blood flowing from a wound (cf. the discussion of kelaine/fhs in the same sense, kappa 1284). See Führer; Handschur 193-97, 210ff.; and Dürbeck 306-07, 156.
