The headword, cognate with chi 264, literally means "the stretching out of the hand" from xei/r ("hand") and ten-/ton- ("stretch, extend"). As a result of the practice of voting by show of hands, the word came simply to mean a vote. See also Hesyschius s.v.

[2] Quotation not identified by Adler but identifiable via the TLG as Herodian, Ab excessu divi Marci 7.10.5, on Maximus and Balbinus, two of the cast of characters in 238 CE, the Year of the Six Emperors. [Though Adler did not make this specific connnection, she was right to capitalize *sebastoi/, the term referring first to Augustus (Octavian) and later to other deified emperors; see alpha 4413 and kappa 1197. The word when uncapitalized refers to worshippers; see sigma 178.] See on the source-identification Theodoridis' Photius edition, vol.II p.LXXXI.
