Epithalamium, a nuptial song, sung before the bridal chamber in honour of the newly-wedded couple, particularly among the Greeks and Romans, of whom Theocritus and Catullus have left notable examples; but the epithalamium of Edmund Spenser is probably the finest specimen extant of this poetic form.
