(Español) Hojas de piedra

The Fisherman used sophisticated tecniques to flake extremery thin slivers of stone, which had no apparent utilitarian purpose.

Beginning usually with a slice of silica, these leaf-shaped objects were produced using a painstaking knapping operation. In the first stage the overall form was established by striking the stone roughly with a harder rock; this was followed with less and less forceful strikes. In the final stage bone or other softer material was used to exert pressure until the desired shape was obtained. These objects were manufactured using the same technology applied to the production of stone tools such as harpoon points, blades and boring tools, but with these very thin slices the craftsman took his skill to the limit. In spite of this, these instruments show no signs of ever having been used. For the ancient fishermen, the time spent on such stones must have been justified by some unknown symbolic value the stones held, perhaps related to the skill the workman demonstrated by making them.
