AN ENGRAVED SLATE FRAGMENT FROM WALYUNGA, WESTERN AUSTRALIA

WA Museum Records and Supplements | Updated 1 decade ago

Abstract - A small engraved fragment of slate from an archaeological site near Perth is analysed by intensive microscopic examination and through replication experiments. Various types of markings are present on both faces of the plaque. These intentionally made incisions are identified and distinguished from the numerous taphonomic marks also present. The anthropic markings are described in terms of their production processes, including the sequence in which they were made, and the directions from which they were drawn, almost certainly by a steel tool. It is concluded that the object was engraved on both sides before it was fractured and then worn by sediment. One side bore a very small structured arrangement that may have been iconic, the other a rectangular grid pattern. Both were engraved with a steel point, and possibly with the same tool.
