χειρορρέκτης
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)
χειρορρέκτης: -ου, ὁ, (ῥέζω) = χειρουργός, Ἡσύχ. (ἔνθα ἡμαρτ. γραφ. χειροέρκτης).
