Question

which art historical period can this work be attributed to?

Explanation:

The image shows a Viking ship, which is characteristic of the Viking Age (part of the Medieval period, specifically the Early Middle Ages or the period of Norse/Viking art and culture). Viking ships are iconic artifacts from the Viking Age (roughly 8th - 11th centuries), associated with Norse art and the cultural production of that historical period. So the work (the Viking ship) can be attributed to the Viking Age (or the period of Norse/Medieval art related to Viking culture).

Answer:

The work (Viking ship) can be attributed to the Viking Age (or the period of Norse art, part of the Medieval period, specifically related to Viking cultural production, roughly 8th - 11th centuries).
