This research report presents the findings of a study on artefact 'Elvet Bridge 4027', a previously unidentified buckle recovered from the River Wear in Durham, England. The report explores the possible materials and methods used in the construction of the artefact, and discusses the significance of the decorative elements present on the buckle in the context of early 15th-century English society. Possibilities of who the object may have belonged to are also discussed. The report provides information on the regional context of the find site and the materials used in the production of medieval buckles in England. A crux of this research arises when delving deep into the widely accepted dating for this typology of buckle. It is discovered that the brass effigies, which have been the basis for assigning a date of 1390-1420 to similar buckles, do not actually depict a 'lyre-shaped' buckle on the depicted deceased. Instead, they only show a 'lyre-shaped' strap end and/or a square-shaped buckle. This research challenges the previously held beliefs about the dating of this typology of buckle.
