Swedish and foreign archives contain a number of medieval diplomas, letters and other documents where scribes have imprinted text. Some of these have been known and their identity has been established, but many have of course remained unknown until now. Among the known scribes are Birgitta Birgersdotter, Bishop Hans Brask, Birgitta's confessor Peter Olofsson of Skänninge and Bishop Henrik Tidemansson. Many scribes have been linked to various monasteries and convents. Through great expertise and diligence, Per-Axel Wiktorsson, professor emeritus of the Swedish language and associate professor of Nordic languages at Uppsala University, has now been able to identify 934 of the medieval Swedish scribes. This is a 30-year collection period that Wiktorsson has spent time analyzing the writing styles of these scribes. Based on eight letters, Wiktorsson tries to analyze the writing style. The letters selected are: g, w-, æ, ø, y, -n, k and h. At least in diplomas, the letters in the first line often show a different design. For this reason, letters have primarily been chosen from the following lines of the diplomas. Hereafter, some forms of writing are given, which may tell us something about the language of the writer. Where possible, it is also indicated how the scribe wrote his own name. Finally, some sources for our knowledge of each scribe are mentioned. Wiktorsson defended his doctoral thesis in 1976 on Södermannalagen's B-handwriting and has published a number of linguistic works. He published a new edition of Äldre Västgötalagen in 2011.
