Lead possible weight. Cast and possibly originally discoid weight, either flattened or trimmed to a hexagonal form. Patinated. The mass may suggest this to have represented three Viking-Age units of 4.07gms as used for silver bullion transactions, or one half of an ora/ore, the contemporary equivalent of an [underweight] ounce. Qualifying this suggestion, it should be acknowledged that examples of values of odd numbers of units are fairly rare in what was effectively a duodecimal system. Suggested date: Early Medieval, 850-950

Diameter: 16.5mm, Thickness: 8.1mm, Weight: 12.42gms


The subject of Viking Age metrology is discussed for Flixborough, North Lincolnshire by Wastling 2009 (Wastling, L.M., 'Lead and lead alloy mensuration weights', in Evans, D.H. and Loveluck, C., Life and Economy at Early Flixborough c.AD600-1000, Excavations at Flixborough volume 2, Oxbow, Oxford and Oakville, pages 422-424). Wastling draws on Wallace 1987 for weights from Dublin using a module of 4.43gms (Wallace, P.F. 'The Economy and Commerce of Viking Age Dublin', in K. Duwel et al, Untersuchengen zu Handel und Verkher der vor- und fruhgeschichtlichen Zeit in Mittel- und Nordeuropoa, Teil IV. Der Handel der Karolingerund Wikingerzeit, Gottingen), and on Kruse (1988, 1992) for weights of a more general Scandinavian currency using a module of 4.07gms (Kruse, S. 1988, 'Ingots and Weights in Viking Age Silver Hoards', World Archaeology 20, 265-381; Kruse, S. 1992, 'Late Saxon Balances and Weights from England', Medieval Archaeology 36, 67-95). Kruse bases calculations on Nielsen 1983, on Hedeby, to arrive at the figure of 4.07gms (Nielsen, H-O, 1983, 'Rontgenologische und metrische Untersuchungen an zwei Kugel-Gewichtssatzen aus Haithabu', Berichte uber die Ausgrabungen in Haithabu 18, 109-120, Neumunster). These details were requested by Helen Geake, though this reporter regrets his lack of facility with the imposition of appropriate accents for the Continental sources cited by Wastling. These appear in their proper form in the bibliography of the Flixborough volume.
