[1] = Synagoge sigma55, Photius sigma156 Theodoridis. The headword is the perfect middle participle, masculine singular nominative, of sobe/w (see sigma 761, sigma 762). It might be a generic lexical reference. If it is not, Theodoridis in his edition of Photius suggests that a likely source is Palladius, Dialogue on the Life of John Chrysostom 18.3, but there are several other possibilities, two of which Theodoridis himself cites (Galen, ps.-Longinus). At any rate, the source is not the quotation given here, where the headword occurs in the dative singular. According to Cunningham (in his edition of the Synagoge), this or a closely similar set of glosses appear in a number of mss of the Lexicon of Cyril.
[2] Aelian fr. 68a Domingo-Forasté, 65 Hercher (although Adler reports that Bernhardy disputed the attribution to Aelian).
