This name was used by Edmund Spenser in his poem 'The Faerie Queene' (1590), where it belongs to a sister of Belphoebe who allegorically represents married love and chastity.
In Breton legend it is borne by the mother of Saint Budoc, a 6th-century princess of Brest (however, the name Eleanor was not coined until the 12th century). It was used for a character in Paul Le Flem's opera Le Rossignol de Saint-Malo (1938) and also occurred briefly in the French TV series Kaamelott (as Azénor).
