Druids, Celts, and Romans
by James Francis Smith
Before the dawn of written history, horsemen from the steppes of Russia swept across the European continent In addition to bringing horses and iron to the continent, the Celts invented steel, chain mail, a yoke for the horse, the spoke wheel with its iron tire, and the iron plow, which enabled European nomads to settle in communities. In 387B, the Celts invaded Rome, this is their first encounter.
