Most recently, however, Karl Kügle has asserted that the source was made in Ivrea itself, by musicians connected to the Savoyard court (possibly Jehan Pellicier), in the 1380s or 1390s.
Under senare tid har Karl Kügle hävdat att Codex Ivrea författades i Ivrea, sannolikt av musiker med anknytning till Huset Savojen, eventuellt av Jehan Pellicier, under 1380- eller 1390-talet .
