EEN VROEG TECHNISCH MONUMENT IN NOORD-DUITSLAND: DE 'OFFERSTEEN' VAN PLUMBOHM, NEDERSAKSEN
Samenvatting
An enormous erratic boulder at Plumbohm near Hitzacker, in de easternmost part of Lower Saxany (Germany), is commonly known as the Opferstein (sacrificial stone). The stone shows a peculiar pattern of artificially cut groaves which enclose round (Ø 50-60 cm), square (50-60 x 50-60 cm) or rectangular areas. In the author's opinion the stone, a granite, was used as a quarry, the marks showing that the production of querns was intended. Granite querns were in general use in settlements in northern Germany during the first half of the first millennium AD.
