In the 970s and after England developed a remarkable monetary system characterised by standardised coin-types naming king, mint-place andindividual maker ('moneyer') which were issued at up to seventy places across the kingdom, from York to Exeter and Dover. Every few years these coinswould be brought in and replaced with a new type. Thanks to payments of tribute to the Vikings who menaced England during the reign of Æthelred, tensof thousands of silver pennies of most of these types have survived in hoards from modern Scandinavia.

Yet one particularly striking and historically important type remains poorly represented among them: the famous Agnus Dei (Latin for Lamb of God)type. Only 21 specimens have been discovered, all but four of them in Scandinavia or the Baltic. One of the latest to come to light was found nearEpping, Essex, in 2008. It was subsequently bought for the Fitzwilliam Museum (accession number CM.1-2009).

Uniquely for the succession of types running from Edgar to Harold II in 1066, the Agnus Dei coinage dispenses with a representation of the king onthe obverse and with the usual cross on the reverse. In their place, one finds a representation of the Lamb of God and of the Holy Dove. These imagesfind extensive parallels among manuscript illuminations, sculpture and metalwork of the period, and demonstrate that the designers of coins were verymuch in touch with the artistic mainstream, and therefore presumably with the deep resonances which attached to these images. Both emphasise thepeace-bringing power of Christ and the Holy Spirit
