Made within the tradition that transmitted the account, though not by a witness to it.
Painted three centuries after the text it illustrates, for a Burgundian court manuscript. By this date the narrative had an agreed geography and an agreed cast, and a reader encountering the story here would have met the pictures before the questions.
In 1148, according to the account, a knight of Cashel collapsed while dining, was thought dead for three days and nights, and then revived. What he described was not a glimpse but an itinerary: a guide, a sequence of named places, specific punishments matched to specific sins, a bridge, a beast, a wall, and finally light.
It was written down within a year or two by an Irish monk living in Regensburg, in Latin, and it travelled. Within three hundred years it existed in more than a dozen languages, in illuminated court manuscripts and in cheap printed editions with woodcuts, and any reader meeting it had almost certainly seen the pictures first.
What the source is
A Latin narrative composed at Regensburg shortly after the events it describes, recounting a three-day apparent death and a guided journey through a structured otherworld.
It became one of the most widely copied texts of the European middle ages, and the version most readers encountered was already illustrated.
The report
No passage reproduced - Excerpt not published - edition and page not yet verified
A public-domain Latin edition exists - Oscar Schade, 1869 - and could be quoted. This project has not yet checked a passage against it, and prints nothing it has not opened.
Why it is in this archive
This is the archive's clearest case of a report acquiring a map. The narrative does not merely describe strange things; it describes them in order, in named places, with a topography that later texts and later pictures reproduce.
Once a report has a geography, it becomes very hard to ask which parts were reported and which were inherited. A witness who has read one of these accounts - and after 1150, most literate witnesses in Latin Europe had - is not describing an unfurnished experience.
The text is also unusually honest about its own construction. Marcus says he is writing what he was told, in Latin, for a particular audience, at a particular abbey. He is a named intermediary who does not pretend to be transparent.
The words the source uses
Given in the language they were written in, with a plain rendering. None is treated as equivalent to a term from another tradition.
- visio
- vision
- The word in the title, and a genre label as much as a description. By the twelfth century a visio was a recognised kind of text with expectations attached.
How close is the source?
Recorded by someone close to the witness or the event, but not dictation.

Once a report has a map, it becomes easy to forget to ask which parts were observed and which were inherited.

Provenance notes
- The date of 1148 is the text's own. It has not been corroborated by this project against any other source.
- Naming the knight does not establish that a knight of that name collapsed in that year.
The Latin text and the 1869 edition are both out of copyright. Neither is mirrored here.
