Rune-like symbols appear as cave markings as early as the late Bronze Age (circa 1300 BC), but their use in ritual and as an oracle for consultation must certainly pre-date their use as a written language.
The fact that the runes were each given meaningful names confirms that they had some magical or religious significance to their users long before they emerged as an alphabet for records and messages.
The word Rune itself comes from the old Norse Runa meaning a secret or mystery, and it seems likely that the early Runemasters and Runemistresses were considered to have some magic or mystic power in their understanding of the runes.
