 The original "Amlóði" story has been surmised to be derived from a "10th-century" Old Icelandic poem, but no such poem is known.The "hero as fool" story has many parallels (Roman, Spanish, Scandinavian and Arabic) and can be classified as a universal, or at least common Indo-European, narrative topos.The two most popular candidates for written works that may have influenced Saxo, however, are the anonymous Scandinavian "Saga of Hrolf Kraki" and the Roman legend of Brutus, which is recorded in two separate Latin works.
