The first paragraph of this entry (i.e. without the section on Aristophanes) appears also in the Synagoge, Lexica Segueriana 336.17 and Photius, Lexicon pi598 Theodoridis; cf. also Hesychius pi1451-52. The adjective pe/peiros, like its English translation, can be literally applied to fruit (see e.g. alpha 3657 and delta 1549) and other produce but also figuratively to (e.g.) women. In this instance its masculine/feminine accusative singular or neuter nominative/accusative singular must be quoted from somewhere; there are numerous possibilities.
[1] o)pw/ra: the season between the rising of Sirius and Arcturus, late July to early September; see LSJ s.v.
[2] Aristophanes, Ecclesiazusae 895-897. As Ussher (below) 199 notes ad loc., toi=s pepei/rois should refer to the maturity of youth, but the hag uses it of herself. See also Henderson (below), 103-104, on the banter between the young woman and the hag. Henrichs (below) 10-12 discusses the use of the adjective in describing a woman in the Cologne Archilochus (P.Col. inv. 7511) and, 21, its various meanings: "when applied to women, pe/peiros could have any of the following connotations: sexually experienced (as in Aristophanes), middle-aged (as in Honestus), or of marriageable age (as in Plutarch)."
