= Synagoge pi771 and Photius pi1487 Theodoridis; cf. Hesychius 4249. The headword, in the dative singular (masculine or neuter) is taken to be quoted from Homer, Iliad 6.169, where it is used to describe a folding double-tablet. The adjective is derived from the root of the verb ptu/ssw ('fold'), and the gloss here is simply a middle participle of that verb.
