[1] Headword and gloss are from the Synagogê (Lexica Segueriana eta.248.23). Also in Photius, Lexicon eta31 (Theodoridis). Perhaps the origin is a scholion to Plato, Republic 547b7 where this term, very rare in all periods, occurs.
[2] (ἀγέτα is the Doric form of the vocative of ἠγέτης .) Quoted from Greek Anthology 6.167.2, but corrupting the original text, which is: ὠ δισσᾶς ἀγέτα θηροσύνας ; “o guide of the double chase”. It is an invocation to an unidentified god who loves both hunting and fishing, made by Kleonikos, who is both hunter and fisherman.
