Abstract

The gnomon hole has a semicircular vertical section 50 mm wide and 51 mm deep. Eleven hour lines extend from winter to summer solstice. The three day curves have been engraved always equidistant from each other and from the lower edge of the conical surface. Dots are visible at the junctions of hour lines and winter solstice.
