R. J. Cholmeley, M.A., The Idylls of Theocritus

[15] Μενέλαε τεὰ νυὸς ἅδε for νυός see xv. 77. The trochaic caesura in the fourth foot of a hexameter is exceedingly rare in Greek, and may generally be excused by the close conjunction of the words forming it or by elision, Monro, Hom. Gram. § 367, but cf. Odyss. xvii. 399 μὴ τοῦτο θεὸς τελέσειεν. There is however no true example in the Alexandrian poets. Hence Meineke here Μενέλα τεὰ ἁ νυὸς ἅδε.
