Title |
Romano-British lower rotary quern stone (section) |
||
Description |
English: Fragment of the lower stone of a weathered granite rotary quern with a central hole for a wooden spindle to hold it to the upper stone of the quern which would have also been perforated centrally. The spindle would have allowed the upper section of the two-part quern to be rotated over the base section, with the grain between the two, so that it was ground into flour. The upper stone is now broken into two pieces, and the larger piece is also pictured here. The diameter of the larger piece is about 290 mm and the height about 80 cm, and the diameter of the eye or hole about 30 mm.
The granite is medium grained and contains inclusions of pinky quartz and colourless mica or muscovite. The granite probably derives from the nearby outcrop on Tregonning Hill in Breage. This quern fragment was found along with other fragments of greisen and granite rotary querns in a field where an earlier hedge has been moved so that these fragments my have been incorporated into this hedge in the past, and have since been strewn around the field. Quinnell (2004) illustrates a similar example from Trethurgy on page 150, Fig.75, No.S50, which is from a 4th century AD layer. Romano-British period |
