The list is based on Menge but with a few changes and updates. In particular, the earliest surviving manuscript is considered to be Karlsruhe (dated to 1455 ca), rather than Zurich (which, after Welker, is now dated 1475 ca).

The Zurich illustration with the misleading MCCCCL date:

DeepL translation of a couple of passages. Schnell's observations on the area of provenance are also interesting:

H. H. Menge initially referred to the Zurich manuscript as the earliest witness on the basis of the illustration on the verso of p. 120, which shows a child being led into a house for writing lessons, which bears the date 1450. However, this was no longer upheld by Welker, who dated the manuscript to around 1475. The year 1450 may go back to the model that was used for the Zurich copy, but perhaps also to a real house that the illustrator took as a model and above whose door this date was engraved.

The geographical distribution of the manuscript tradition of the full manuscripts of the 'Regimen' is limited to a relatively small area: all manuscripts originate from the Alemannic language area. The center of the tradition was probably the Zofingen - Aargau area (today's Canton Aargau), the Upper Rhine and Alsace with the cities of Basel, Freiburg and Strasbourg. The temporal distribution is just as constant. Without exception, the manuscripts were written in the second half of the 15th century. The example of the Budapest manuscript shows that the text had lost none of its relevance even in the first half of the 16th century. The oldest surviving manuscript is the Karlsruhe Codex.
