The meaning of stampede is “crash, bang, uproar” so putting these meanings together “traherne stampede” = “a crash of iron”. Now this begins to sound musical… a gong. Or as iron is associated with Mars alchemically we could even get “war of the worlds’ out of it… an uproar or crash courtesy of Mars. Still I think it is time to put my casual obsession to rest… don’t you? Thanks for the post!
