Idyll XVIII, also titled Ἑλένης Ἐπιθάλαμιος ('The Epithalamy of Helen'), is a poem by the 3rd-century BC Greek poet Theocritus.[1] The poem includes a re-creation of the epithalamium sung by a choir of maidens at the marriage of Helen and Menelaus of Sparta.[2] The idea is said to have been borrowed from an old poem by Stesichorus.[3]
