Soapstone artifacts originate from Late Mesolithic or Early Neolithic sites in Western Norway (there are also several stray finds). Only those in the Late Mesolithic layers can be securely attributed stratigraphically. Chronologically they are attributed to 6400-3300 BCE and represent a material culture of the fishing oriented Stone Age societies of the region.

Dataset includes 30 sinkers for line fishing. They are various in size and shape. All are engraved with one or several lines that are the subject of further technological study. Usually, such sinkers are featured with furrow — a wider engraving supposedly used to tighten the line. There are also finer ones, often read as ornamentation. The origin of soapstone is suspected to be local, but is generally unclear.

Metadata

Description

A small grey three-sided sinker with sides in a shape of a sphere segment. The furrow is horizontal and crosswise. The site context is secure, same as the chronological attribution.
