For this headword see also epsilon 3874 and epsilon 3875. After the initial definition 'a Roman cloak', the present entry is an approximation of Artemidorus 2.3.
Neither the headword itself nor the two synonyms drawn from Artemidorus (on which see nn. 2-3 below) are Latin words, and of the three, only birrus occurs in Latin texts. Conversely, among the three only the headword is manifestly Greek in origin. Perhaps these are words used among Greek populations to refer to a distinctively Roman cloak such as the legionary lacerna or sagum.
[1] Comparably, according to Adler, in the unedited Ambrosian Lexicon (2685).
[2] In addition to Artemidorus, Etymologicum Magnum 402.49 and the scholia to Lucian (36.37 and 77.20 Rabe) also offer this word as a synonym for the present headword; and cf. mu 139.
