ἅπανθ' ὁ μακρὸς κἀναρίθμητος χρόνος φύει τ' ἄδηλα καὶ φανέντα κρύπτεται· κοὐκ ἔστ' ἄελπτον οὐδέν, ἀλλ' ἁλίσκεται χὠ δεινὸς ὅρκος χαἰ περισκελεῖς φρένες. → Long, unmeasurable Time brings to light everything unseen and hides what has been apparent.

Nothing is beyond expectation; the dread oath and the unflinching purpose can be overcome.
