[1] = Synagoge pi704 and (e.g.) Photius pi1359 Theodoridis. Headword and gloss are dative plurals, the former presumably extracted from somewhere (but not from the quotation supplied; see n. 3 below).
[2] The same headword and gloss, but this time in the nominative singular; cf. Hesychius pi3879.
[3] An approximation of Menander Protector fr. 43 FHG (4.235b), Blockley 19.1 (172-173), via Constantine Porphyrogenitus, Excerpta de legationibus 205.5-10; cf. sigma 413 (where the personal name is given, more accurately, as Silziboulos). The form of the headword that appears in this quotation is dative singular. During his embassy of 576, Roman envoy Valentinus recalls the alliance Silziboulos had earlier made with the Romans and urges the Turkish khan Turxanthus to wage war on the Persians. On Valentinus and Turxanthus, see epsilon 659 note. See further excerpts from this fragment at epsilon 659, epsilon 719, epsiloniota 208, omicron 84, and sigma 413.
