= Photius, Lexicon pi1407 Theodoridis (but see below); and cf. Pollux 10.191 where protonion is included in a list of temple accoutrements, perhaps garments.
[1] So here, but Photius' original has Pandrosos (pi 182), also mentioned by Pollux. The discrepancy could be put down to a simple error on the Suda compiler's part if the 'Pandora' he meant was the primal Eve-figure of that name, whose eponymous box or jar let loose the world's evils (see in brief OCD4 s.v.). However, more probably this is a conscious correction within the scope of specifically Athenian mythology: a change from Pandrosos one of the daughters of Kekrops to Pandora one of the daughters of Erechtheus.
