Originally in Greece a funeral ovation written in couplets of hexameter followed by a pentameter, the word 'elegy ' was later applied by Ovid to describe love poems such as his Amores. Donne's elegies followed Ovid and were sometimes witty and ribald. Generally the term elegy signified a meditation on love inflected with a sense of mortality.
