Adler reports an identical entry in the Ambrosian Lexicon (563); cf. Etymologicum Gudianum and a scholion on Hesiod, Works and Days 775, where the phrase o)/is pei/kein "to shear sheep" occurs (web address 1). Apollonius the Sophist, ps.-Herodian, and Hesychius gloss the infinitive with cai/nein "to card." The verb is usually pe/kw (pi 918), but (besides the infinitive in Hesiod), pei/kete is attested in Homer (Odyssey 18.316).
