Visio Tnugdali
12th-century religious work
The Visio Tnugdali ("Vision of Tnugdalus") is a 12th-century religious text reporting the otherworldly vision of the Irish knight Tnugdalus. It was "one of the most popular and elaborate texts in the medieval genre of visionary infernal literature".
The Visio had been translated from the original Latin forty-three times into fifteen languages by the 15th century. The work remained most popular in Germany, with ten different translations into German, and four into Dutch. With a recent resurgence of scholarly interest in Purgatory following works by Jacques Le Goff, Stephen Greenblatt and others, the vision has attracted increased academic attention.
The work
The Latin text was written down shortly after 1149 by Brother Marcus, an Irish itinerant monk, in the Scots Monastery, Regensburg in Germany. He reports having heard Tnugdalus' account from the knight himself and to have done a translation from the Irish language at the Regensburg abbess' request. The story is set in Cork, Ireland in 1148.
Tnugdalus, the protagonist, was later also called "Tundalus", "Tondolus" or in English translations, "Tundale". These names all derive from the Middle Irish Tnúdgal meaning "desire-valour" or "fierce valour".

Why this record matters
“Visio Tnugdali” is worth following because a concise public description often conceals a longer documentary argument. Here, Visio, Tnugdali and 12th-century provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q1938472. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1149 and 1148.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
