These Arabs, the man Mahomet, and that one century, - is it not as if a spark had fallen, one spark, on a world of what proves explosive powder, blazes heaven-high from Delhi to Granada! I said, the Great man was always as lightning out of Heaven; the rest of men waited for him like fuel, and then they too would flame.
Thomas Carlyle (1864). “Sartor Resartus”, p.242
