Description: | Cast copper alloy rotary key of probable medieval date (1150-1400). The key is broadly sub-rectangular in plan with a similar shaped cross section. The end of the shank of the key is hollow, suggesting that it was cast in a three part mould. The handle loop of the key is oval in shape; the upper edge of this has visible wear through use. The loop of the key has also been damaged by movement in the plough soil and a vertical crease in the metal is clearly visible where the surface patina has been removed. The loop extends into the shank of the key which is rectangular in plan. From the lower edge of one end a relatively crudely shaped bit extends. The bit has been cut and filed into shape. There are no obvious decorative elements on any face of the key. It is a mid green colour with an even but slightly abraded patina. This abrasion and movement in the ploughsoil has caused the key to become asymmetrical and the edges to become rounded. Where the abrasion has been most significant the patina has been removed and light green active corrosion is present. The shank of the key is hollow and filled with a earth, the tip of the pipe has been torn. A direct parallel for this key has not been found. However a number of very similar rotary keys are shown in G. Egan's 'Medieval Households' pages 111-112. These are all dated from the late 12th - to late 14th centuries (1150-1400). Therefore a similar date is suggested here.The key measures 41.3mm in length, 14.6mm width and is 4.9mm thick (the bit of key measures 7.5mm length, 8.6mm width and is 3.1mm thick). The key weighs 4.83 grams. | Publisher: | http://finds.org.uk | Source: | Portable Antiquities | Identifier: | http://finds.org.uk/database/artefacts/r... | Go to resource |
