Description: | A complete cast copper alloy rotary key of probable Medieval dating (1150 to 1400 AD).The key is irregular in plan and cross section. The key can be described in several sections: The bow or handle, shank and bit.The bow is sub lentoid (diamond) in shape, with two sub rectangular projections located at the central point on the outside edge. Four circular perforations (holes) are present in the bow, positioned irregularly. It has a rectangular cross section. The shank is attached to the bow at the mid point of the right hand side. A faint rectangular doublen moulding or collar is present at the junction between shank and bow.The shank consists of an rod, rectangular in plan and sub rectangular in cross section.The bit is sub rectangular in plan and cross section. The clefts consist of two sub square notches on the internal edge. A small hook is present at the end of the bit.The key is a dark green colour and has an even surface patina.The key measures 72.41mm in length, 26.77mm wide and is 6.97mm thick. It weighs 20.5 grams.From the size of the key and the presence of a solid shank it is likely that the key would have been used to lock a door rather than a casket or chest. Chest locks tend to have a hollow shank and are significantly smaller (ibid: 111). The keys illustrated in Egan (1998, 111-119) are all dated from the late 12th - to late 14th centuries (1150-1400). Therefore a similar date is suggested here for this example.Reference:Egan, G. Security Equipment in Egan 1998Egan, G. 1998 The Medieval Household Daily Living c.1150-c.1450.
