Description: This cast openwork mount, slightly convex in shape, takes the form of an octagonal snake in the act of biting its own body. When viewed from above, the snake's head features a pointed snout and two prominent round eyes. The body is adorned with three rows of raised dots and tapers toward the tail, which terminates in a tightly twisted end just above the head. The single leg of the snake wraps around its body three times and concludes with a second scroll that diagonally traverses the tail. The intertwined tendrils of the leg create two small fastener loops at one end of the mount, while the body forms a large loop at the other; some signs of wear suggest that this object may have functioned as one part of a clasp. The reverse side of the mount lacks decoration.
