We find rhabdomancy a popular form of divination among the Greeks, and also among the Romans. Cicero in his "De Officiis" alludes to it. "If all that is needful for our nourishment and support arrives to us by means of some divine rod, as people say, then each of us, free from all care and trouble, may give himself up to the exclusive pursuit of study and science." Probably it is to this rod that the allusion of Ennius, as the agent in discovering hidden treasures, quoted in the first book of his "De Divinatione," refers. According to Vetranius Maurus, Varro left a satire on the "Virgula divina," which has not been preserved. Tacitus tells us that the Germans practised some sort of divination by means of rods. "For the purpose their method is simple. They cut a rod off some fruit-tree into bits, and after having distinguished them by various marks, they cast them into a white cloth.... Then the priest thrice draws each piece, and explains the oracle according to the marks." Ammianus Marcellinus says that the Alains employed an osier rod. The fourteenth law of the Frisons ordered that the discovery of murders should be made by means of divining rods used in Church. These rods should be laid before the altar, and on the sacred relics, after which God was to be supplicated to indicate the culprit. This was called the Lot of Rods, or Tan-teen, the Rod of Rods. But the middle ages was the date of the full development of the superstition, and the divining rod was believed to have efficacy in discovering hidden treasures, veins of precious metal, springs of water, thefts, and murders. The first notice of its general use among late writers is in the "Testamentum Novum," lib. i. cap. 25, of Basil Valentine, a Benedictine monk of the fifteenth century. Basil speaks of the general faith in and adoption of this valuable instrument for the discovery of metals, which is carried by workmen in mines, either in their belts or in their caps. He says that there are seven names by which this rod is known, and to its excellences under each title he devotes a chapter of his book. The names are: Divine Rod, Shining Rod, Leaping Rod, Transcendent Rod, Trembling Rod, Dipping Rod, Superior Rod. In his admirable treatise on metals, Agricola speaks of the rod in terms of disparagement; he considers its use as a relic of ancient magical forms, and he says that it is only irreligious workmen who employ it in their search after metals. Goclenius, however, in his treatise on the virtue of plants, stoutly does battle for the properties of the hazel rod. Whereupon Roberti, a Flemish Jesuit, falls upon him tooth and nail, disputes his facts, overwhelms him with abuse, and gibbets him for popular ridicule. Andreas Libavius, a writer I have already quoted in my article on the Wandering Jew, undertook a series of experiments upon the hazel divining rod, and concluded that there was truth in the popular belief.
