The Flamen Dialis, the high-priest of Jupiter in Rome, had to observe an extraordinarily large number of taboo rules. He was not allowed to ride, to see a horse or an armed man, to wear a ring that was not broken, to have a knot in his garments, to touch wheat flour or leaven, or even to mention by name a goat, a dog, raw meat, beans and ivy; his hair could only be cut by a free man and with a bronze knife, his hair combings and nail parings had to be buried under a lucky tree; he could not touch the dead, go into the open with bare head, and similar prohibitions.
