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 soapstone sinker covered with deep and wide engraved lines. Two lengthwise furrows cross the front-back and left-right sides of the stone. Perpendicular to them, notches cover all sides of the sinker. The context of the site where the piece was found is dubious.

Capturing strategy

161 digital images in RAW format. 6 rounds of imaging with different object orientations: bottom-up, up-bottom, front side, back side, left side, right side. Sharp edges were acquired with additional precision. SfM photogrammetry, static camera within scenes, an artifact on the turntable, black background; scaled from calibrated metric scale bars. Remote shutter release.
