In Norse tradition, runes held a magical significance, and 'casting the runes' was a way of seeing into the future. There are no such magical connotations associated with runes in Tolkien's work, where they are presented as no more than a writing system.
On the topic of the origins of runes, it should be noted that while our modern word 'rune' is certainly descended from the Old Norse rún, it also seems to have been influenced by an Old English verb rúnian, 'to whisper', so that runes are literally 'whispering signs'. |
