[email protected] Abstract: In Mayen the production of lava rotary querns of ‘Iron Age type’ continued from the late La Tène period into Julio-Claudian times. The lower quernstone possessed a domed grinding face and the upper stone was double concave in section. While the surfaces of these querns are usually pecked, late examples show a segmented radial grooving on the grinding surfaces. Handle sockets with elbow- shaped (L-shaped) perforation were already an innovation of the late Iron Age.
