  Archaeological textiles are often highly fragmented, and solving a puzzle is needed to recover the original composition and respective motifs. The lack of ground truth and unknown number of the original artworks that the fragments come from complicate this process. We clustered the RGB images of the Viking Age Oseberg Tapestry based on their texture features. Classical texture descriptors as well as modern deep learning were used to construct a texture feature vector that was subsequently fed to the clustering algorithm. We anticipated that the clustering outcome would give indications to the number of original artworks. While the two clusters of different textures emerged, this finding needs to be taken with care due to a broad range of limitations and lessons learned.

  Ships appear in several, varied contexts in the Viking Age. These contexts are in this article used to discuss the ship’s connection to overall pre-Christian, Norse mentality. Kennings such as byrjar drösla (sailing wind horse) shows the ship’s connection to horses, considered as independent agents able to cross between spheres. This, in particular, is discussed in connection to Freya’s hall Sessrúmnir, a hall which also appears on a list of ships in Skaldskaparmál. Based on the analyses presented in this article, it is argued that ships were connected to a complex, inference-based framework of understanding where they had several, varied identities and roles. Interpreting burial ships, such as the Oseberg ship, simply as burial homes or death vessels might therefore severely limit our present understanding of the multifaceted nature of the ship in pre-Christian, Norse mentality.
