[1] = Synagoge sigma201, Photius sigma517 Theodoridis; cf. Hesychius sigma1698, Pollux 1.107. The headword is aorist middle participle, masculine plural nominative, of ste/llw; it is glossed by the corresponding aorist active participle of the same verb. (For other forms see sigma 1077 and sigma 1078.) As the gloss suggests, ste/llw admits both transitive and intransitive usages in both the active and middle, and is capable of taking on a wide variety of meanings, including make ready, dispatch, send, furl, contract, cover, conceal, etc. The present headword is evidently extracted from a literary source, but not from the quotations that follow, where other forms of the verb appear. Similarities between a scholion to Oppian, Halieutica 5.529, and Hesychius sigma1698 suggest Oppian as a possible source, and the current gloss has been translated accordingly, although unlike Hesychius the scholion to Oppian does not include a particularly close parallel to the present gloss.
[2] Both quotations -- the first of which includes the aorist middle infinitive cited, the second the present middle infinitive -- are taken to be excerpts from Polybius (fr. 220 and 221 Büttner-Wobst), via the Excerpta of Constantine Porphyrogenitus, according to Adler. For Perseus -- the Macedonian king, not the mythological hero -- see pi 1370.
