 Visio Tnugdali

The Visio Tnugdali ("Vision of Tnugdalus") is a 12th-century religious text reporting the otherworldly vision of the Irish knight Tnugdalus (later also called "Tundalus", "Tondolus" or in English translations, "Tundale", all deriving from the original Middle Irish "Tnúdgal" meaning 'desire-valour' or 'fierce valour').It was "the most popular and elaborate text in the medieval genre of visionary infernal literature" and had been translated from the original Latin forty-three times into fifteen languages by the 15th century, including Icelandic and Belarusian.
