Disputatio:Principium Hugenianum
Latest comment: abhinc 5 annos by Andrew Dalby
The Latin term seems most often to be "principium Hugenianum" (middle of page xxii apud Google Books). "Regula Hugeniana" (top of p. VII apud Google Books) seems to be quite different (but I know nothing). Andrew Dalby (disputatio) 13:19, 29 Ianuarii 2019 (UTC)
