This chapter considers the wealth of some of Ireland’s kings, as represented by Viking Age silver hoards, and relates it to investment in the ecclesiastical sphere. While the rich Irish annals do not contain references to hoards or hoarding, there are some mentions of the phenomenon in early literary sources, and these relate to the church. Considering the occurrence of hoards and silver-working on ecclesiastical estates, as well as the status of the cross-marked ingot, it is argued that Viking Age silver hoards were deposited on church land with higher frequency than has hitherto been appreciated. This finding, in turn, suggests Irish secular elites obtained considerable quantities of silver wealth from the Scandinavians and gifted it to the church, with whom they often had close dynastic connections.
