As Though They Had Never Been

"Besides this, however, many of their discoveries [the ancients] were ultimately lost to the world, some, as at Alexandria, by fire -- the bigoted work of a Mohammedan conquerer -- some by irruption of barbarians; and all were buried so long and so completely by the night of the dark ages, that they had to be rediscovered almost as absolutely and completely as though they had never been." -- Oliver J. Lodge, physicist, Pioneers of Science, 1893
