The gridded surface collection at L'Haut des Champs (UF 75) yielded pieces of the upper stones of two different querns, both of Roman type.

Part of the upper stone of a flat rotary quern (Fig. 97). The quern has a vertical edge, with a convex top surface and concave grinding face. No traces of handle holes or central hopper are present. Diameter of stone c. 420mm. Volcanic stone/lava, perhaps from the Auvergne. 380 x 170 mm x Th 80mm (object ID B2002-303-75-1; from grid square [7]). Similar examples are known from excavations on Mont Beuvray (Büchsenschütz and Boyer 1999, 215, nos 34 and 40), both from Augustan contexts.

A substantial piece of the upper stone of a large rotary quern (Fig. 98). The upper face is inclined down towards the centre and has a slight ridge around the circumference; the outer edge of the stone is near-vertical. The grinding face is steeply angled and has large quartz grits protruding; there is some wear around the outer edge; pock-marking towards the centre of the grinding face may be deliberate. What remains of the central eye is angular and not central to the stone, indicating a large elongated eye c. 160mm in length or a more complex arrangement characteristic of a mechanically driven millstone - the precise details cannot be reconstructed from what remains. Diameter of stone c. 600mm. Sandstone, probably from a local source such as Planoise, in the hills close to Autun. 500 x 25mm x Th 140mm (object ID B2002-303-75-2; from grid square [12]). A similar example is known from excavations on Mont Beuvray (Büchsenschütz and Boyer 1999, 215, no. 45), deriving from an Augustan-period context.
