Three of the most remarkable Viking Period silver hoards found on Gotland form the topic of this paper. They all offer viewpoints upon trade, tribute and warfare in Gotland and the East Baltic area. The oldest of them (t.p.q. 870/1) was found in 1999 at Spillings in Othem parish. It illustrates the enormous influx of Arabic silver in its epoch, weighing more than 66kg, of which 17.5kg are made up of about 14,000 coins. Both of the other hoards were found at Ocksarve in Hemse parish, the first in 1920, the second in 1997. The hoard of 1920 i.a contains 112 Byzantine millaresia struck for Constantine IX Monomachos (1042–1055), probably part of the salary of a Gotlandic mercenary and ex-member of the Varangian guard. The second hoard (t.p.q. 999) is interesting from a metrological point of view, as it contains several interlinked payment spirals and bundles containing hack-silver. There is also a magnificent silver sword chape, probably a masterpiece from a Kievan workshop, with a graffito showing two crossed single-edged swords of J. Petersen’s type T, V or W.
