Same entry in the Synagoge and Photius' Lexicon; very similar one already in Hesychius (sigma795; and cf. also a scholion (D scholia) on Homer, Iliad 11.811, where the phrase ska/zwn e)k pole/mou occurs (web address 1). The lexicographers' ska/zei must be quoted from somewhere else.
Skazon is also another name for choliambic meter: see chi 402, chi 424, iota 588.
