κυρωτέον
From LSJ
Τραφὲν ὄρεσι καὶ φάραγξιν ἀγρίαις, κήρυξ πέφυκα τῆς λόγου ὑμνῳδίας. Φωνήν μὲν οὐκ ἔναρθρον, εὔηχον δ' ἔχω (Byzantine riddle) → Raised in the mountains and wild ravines, I have become the herald of hymns that are sung. I have no articulate voice...
Greek (Liddell-Scott)
κῡρωτέον: ῥημ. ἐπίθ., δεῖ κυροῦν, Εὐσ. Ἐκκλ. Ἱστ. 3. 25, 2.
