The precise date of the origin of the Freising Manuscripts cannot be exactly determined; the original text was probably written in the 9th century. They were discovered in 1807 in the Munich National Library during the examination of the manuscripts from Freising near Munich, which was once the centre of a diocese.
During the time of the writing of the two manuscripts (sermons on sin and repentance, a confessional form), bishop Abraham was active (from 957 to 994) in Freising, who also acquired a large estate of land in the Creina province around Škofja Loka (now central Slovenia). For this reason some linguists (e.g. Jernej Kopitar and Rajko Nahtigal) linked him closely to the origin of the Freising Manuscripts and, without any firm evidence, attributed him as being the author of one of the texts and suspected that he was of Slovenian origin.
