Storehouses of parchment

[Helmut Winkler]

It is a technical problem as well, not a question of price only, printing ink is based on oil and does not work well on parchment.

Another issue is the predilection of Italy for using  parchment, while Germany preferred paper for reasons we do not know, there was an extensive trade and this is one of the reasons  why I think the ms. was written in Italy
