In this article, letter spotting was used on a large set of handwritten documents in order to identify those that contain similar script. The main scribe of the Codex Holmiensis D 3 manuscript has yet not been identified in other documents. In the letter spotting process, a set of ‘g’:s, ‘h’:s and ‘k’:s have been selected as templates, and a search has been made for close matches among the mediaeval Swedish charters. This is visualised in the image, where each axis corresponds to the similarity measure used, and it means that spheres close to the origin have very low similarity.  The search resulted in a number of charters, represented by the magenta coloured spheres, that displayed great similarities with the manuscript D 3. The method thus proofed to be a very efficient sorting tool, localising similar script samples.

scriptsThis table shows the D 3 manuscript and four other manuscripts, represented by the magenta coloured spheres, with partly similar appearance of the letters.
