[1] Likewise or similarly in other lexica. The headword is third person singular, aorist indicative active, of prutaneu/w (cf. pi 2994). It might be extracted from the quotation given, though earlier lexica do not have it, and there is another good candidate in Isocrates 4.121.
[2] Though this quotation is otherwise unattested, the name Stryngaios (again sigma 1230) creates a link with Ctesias FGrH 688 F7 and especially Nicolaus of Damascus FGrH 90 F5, on the Mede Stryngaios who was the ill-fated admirer of Zarinaia, widow of the king of the Sakai. The Nicolaus fragment ends abruptly with 'The eunuch [...]', and, as Jacoby notes, the Suda quotation would make a plausible fit there.
