Although it is widely believed that forks were not introduced until the Middle Ages, it is possible to find examples from Roman times that may have been used to serve food rather than as individual eating utensils. This two-pronged fork has a finial in the shape of an ox hoof similar to that on the bronze spoon (20.49.10) also on view in this case.
