Hanging bowls are a distinctive type of artefact of the period between the end of Roman rule in Britain in c. 410 AD and the emergence of the Christian Anglo-Saxon kingdoms during the 7th century. The surviving examples have mostly been found in Anglo-Saxon graves, but there is general agreement that they reflect Celtic traditions of decoration. The bowls are usually of thin beaten bronze, between 15–30 cm (6-12 inches) in diameter, and dished or cauldron-shaped in profile. Typically they have three decorated plates ('escutcheons') applied externally just below the rim to support hooks with rings, by which they were suspended. The ornament of these plates is often very sophisticated, and in many cases includes beautiful coloured enamel work, commonly in champlevé and using spiral motifs. Although their designs and manufacture are thought to proceed from Celtic technique, they are principally found in eastern Britain, and especially in the areas which received Anglo-Saxon acculturation which employed grave goods in burial practices in contrast to Christian practice. Their production is also evidenced in Pictish and Irish contexts, but they seem almost completely absent from the Brittonic areas of Wales, Devon and Cornwall. Three were found in the famous Sutton Hoo ship-burial, as well as one in another mound at the site. Rupert Bruce-Mitford's corpus gives the following breakdown of the locations in modern terms of the 174 finds he includes (many are just one or more elements of a bowl): England 117, Scotland 7, Ireland 17 Norway 26, Sweden 2, Denmark 1, Germany 2, Belgium 1, Netherlands 1 Function The bowls are enigmatic because their intended function is not certainly known. Many have finely-worked escutcheons set centrally within, which makes it unlikely that they could have contained opaque or sticky material such as lamp-fat. The theory that they were used as maritime compasses, with a magnetic pin floated on water within the bowl, is discounted because many have an iron band around the rim which would render this unworkable. Another opinion is that they were used for the Roman custom of mixing wine and water for service at table. Some bowls are too small to make this explanation workable if serving a group were intended. However, in ritual Christian or other meals it would be possible for a group to dip bread into such a wine-bowl in imitation of the Last Supper. Part of the puzzle lies in whether the bowls
