The headword phrase occurs (but with the two words reversed) in an epigram from the
Greek Anthology, 6.246.1, by
Philodemus or Marcus Argentarius;
Charmus, son of Lycinus, is dedicating a horse's equipment to Poseidon after a victory at the Isthmian Games; cf. Gow and Page, vol. I (156-157). Gow and Page (vol. II, 371) assign this epigram to Argentarius, arguing as follows: "6.246 is a highly polished epigram in the manner of
Leonidas; there is nothing similar in
Philodemus, but Argentarius occasionally composes in this style." See also
kappa 1338 (for this phrase in the correct word-order),
kappa 1519 (for the complete hexameter), and further excerpts from this epigram at
sigma 1055 and
psi 66.
