ἀγλαόφωνος
From LSJ
ἐν μὲν γὰρ ταῖς ἐπιστολαῖς αὐτοῦ οὐδὲ μνήμην τῆς οἰκείας προσηγορίας ποιεῖται, ἢ πρεσβύτερον ἑαυτὸν ὀνομάζει, οὐδαμοῦ δὲ ἀπόστολον οὐδ' εὐαγγελιστήν (Eusebius, Demonstratio evangelica 3.5.88) → For in his epistles he doesn't even make mention of his own name — or simply calls himself the elder, but nowhere apostle or evangelist.
English (LSJ)
ον, A with a splendid voice, Procl.3.2.
Greek (Liddell-Scott)
ἀγλαόφωνος: -ον, ὁ ἔχων λαμπρὰν φωνήν, Πρόκλ. Ὕμ. Μούσ. 2.
