= Synagoge pi781, Photius pi1509 Theodoridis (with other references there). Perhaps from commentary on Aristophanes, Knights 1060, where the headword (here nominative singular) occurs in the accusative plural to refer to washbasins for people to use in bathing (see scholia ad loc.). Contrast Hesychius pi4293 where the same headword is defined as a basin for washing grain.
For a different gloss on the same word, see the next entry, pi 3119; and cf. the previous entry, pi 3117, for a related word.
