[1] Aristophanes, Lysistrata 60 (but read o)/rqriai, "at dawn", for the Suda's "standing up").
[2] Of the two senses of ke/lhs, the "horse" meaning is prior, and kappa 1303, discussing the diminutive kelh/tion, admits as much. Nothing supports the notion that ke/lhs means the horse is bareback. See also kappa 1300.
[3] Up to this point, from a scholion on Aristophanes, Lysistrata 59-60 (see above).
[4] From a scholion on Sophocles, Ajax 954. Presumably, "not a normal boat" (but a dinghy), since a dinghy is hardly elaborate. The explanation has nothing to do with the digression on the other meaning of ke/lhs; Adler notes with approval Bernhardy's view that this material belongs with kappa 1288.
[5] Greek Anthology 5.204.1-2 (Meleager [Author, Myth]). Because the Suda's text is mangled, it does not quite make grammatical sense. In the accepted version "rowing" is in the nominative not the accusative, and "Timarion" is in the genitive. The epigram is an extended metaphor comparing Timarion's body to a ship: "The rowing of Cypris [i.e. Aphrodite] no longer keeps afloat the frame of Timarion, the already carved-out dinghy." Find another extract from this epigram at sigma 896.
[6] cf. Hesychius kappa2167, the Synagoge, and Photius kappa555 Theodoridis (with other references there).
[7] The verb is attested in Homer, Iliad 15.679, but it means "jump from horse to horse", and is derived from the primary meaning of ke/lhs, "riding horse"; it has nothing to do with sense "boat". See kappa 1302.
