Cultural and Temporal Context: Originating in the Anglo-Saxon period, specifically during the 8th century
Discovery/Procurement Location: Unearthed in Europe, within the British Isles, more precisely in Norfolk, England, at Surlingham
Materials: Crafted from silver, gilded, and embellished using various techniques including casting, engraving, and chip carving
Description: This is a subrectangular fragment of a decorative mount, slightly curved on the sides, crafted from silver and gilded. The fragment underwent a casting process and was subsequently hand-finished to create an ornate surface. The surviving portion is adorned with a square panel featuring a zoomorphic portrayal of a long-legged feline creature. The creature's body is depicted in profile, with its head turned forward. The fur on its torso, neck, and scruff is intricately rendered using fine ribbed herringbone engraving. The tail of the creature is transformed into a complex carved weave that crosses over the torso and extends to cover the legs and paws. The design is framed by simple borders at the top and bottom, along with vertical borders embellished with diagonal engraving.
