What is 'Water Witching'?
"Some Sorcerers do boast they have a Rod,
Gather'd with Vowes and Sacrifice,
And (borne about) will strangely nod
To hidden Treasure where it lies;
Mankind is (sure) that Rod divine,
For to the Wealthiest (ever) they incline."
Water Witching is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, gravesites, and many other objects and materials, as well as so-called currents of earth radiation (ley lines), without the use of scientific apparatus. Dowsing is also known as divining, water finding, water witching or water dowsing.
A Y- or L-shaped twig or rod, called a dowsing rod, divining rod, a "vining rod" or witching rod is sometimes used during dowsing, although some dowsers use other equipment or no equipment at all. Dowsing appears to have arisen in the context of Renaissance magic in Germany, and it remains popular among believers in Forteana or radiesthesia.
