This paper considers a group of manuscripts of the 12th and 13th century. It focuses on how the transalpine (i.e. austrian and bavarian) writing - and particularly the so-called 'Schraegovaler Stil' - strongly influenced the manuscript production in Friuli. The adoption of a north italian type of 'littera textualis' in the first decades of the 13th century has apparently to be ascribed to the occasional presence of foreign scribes not related to the Hirsau reformed monastic movement. The codicological changes generally affecting the manuscript book production in the same period are also verified.
