An epithalamium (/ˌɛpᵻθəˈleɪmiəm/; Latin form of Greek ἐπιθαλάμιον epithalamion from ἐπί epi "upon," and θάλαμος thalamos nuptial chamber) is a poem written specifically for the bride on the way to her marital chamber. This form continued in popularity through the history of the classical world; the Roman poet Catullus wrote a famous epithalamium, which was translated from or at least inspired by a now-lost work of Sappho. According to Origen, Song of Songs might be an epithalamium on the marriage of Solomon with Pharaoh’s daughter.
It was originally among the Greeks a song in praise of bride and bridegroom, sung by a number of boys and girls at the door of the nuptial chamber. According to the scholiast on Theocritus, one form was employed at night, and another, to rouse the bride and bridegroom on the following morning. In either case, as was natural, the main burden of the song consisted of invocations of blessing and predictions of happiness, interrupted from time to time by the ancient chorus of Hymen hymenaee. Among the Romans a similar custom was in vogue, but the song was sung by girls only, after the marriage guests had gone, and it contained much more of what modern attitudes would identify as obscene.
In the hands of the poets the epithalamium was developed into a special literary form, and received considerable cultivation. Sappho, Anacreon, Stesichorus and Pindar are all regarded as masters of the species, but the finest example preserved in Greek literature is the 18th Idyll of Theocritus, which celebrates the marriage of Menelaus and Helen. In Latin, the epithalamium, imitated from Fescennine Greek models, was a base form of literature, when Catullus redeemed it and gave it dignity by modelling his Marriage of Thetis and Peleus on a lost ode of Sappho.
