[1] For the headword adjective see again mu 94. Here it is apparently masculine accusative singular, quoted from Homer, Iliad 2.42 (where it applies to a chiton; with the scholia there cf. the first gloss here); however, the second gloss treats it as neuter.
[2] This quotation, as Adler notes, was connected by Tiberius Hemsterhuys (1685-1766) with Cicero (kappa 1594). [On the murder of Cicero, 7 December 43 BCE, see Plutarch, Cicero 48.5: "he stretched his neck out of the litter and was slain".] However, a TLG search reveals that it actually comes from Josephus, Antiquities of the Jews 19.271, on the execution of Lupus (web address 1). See on this Theodoridis' Photius edition, vol.II pp.LXXXV-LXXXVI.
