The ancient Romans were renowned for pendulum scrying and their methods were detailed in the writings of Roman historian Ammianus Marcellinus. It is also possible that French seer Nostradamus used this same Roman method of basin scrying by means of a pendulum to produce individual letters that formed intelligible prophetic verses.
The bowl used was a composite material of many metals, meaning it was made of electrum, an alloy of gold and silver. A ring was attached by thread to a wand.
The ring was probably a band of electrum with occult characters engraved upon it. The twenty four letters of the Greek alphabet were engraved into the flange of the basin.
The table used was probably a tripod in which to support the basin. It was made out of branches of laural and had three legs.
Laural was the substance specified by the Enochian angels for the scrying table of John Dee. Another method which has been used in Europe for centuries involves the suspension of a ring from a thin silk thread inside an ordinary water goblet.
The responses come in the form of tapping sounds as the ring gently raps the side of the glass. The seer asks a specific question that can be answered with a yes or a no. A single tap indicates a yes while two taps indicate a no. More than two taps indicates the spirit is not certain of the response.
Another method is to use a sheet of paper with a cross marked upon it. The ring is held suspended over the cross in the left hand upon a silk thread.
A simple question is asked which only requires a yes or no. If the answer is yes it will swing back and forth along the vertical arm of the cross. If the answer is no it will swing side to side along the horizontal arm of the cross.
Some scryers prefer to use a crystal instead of a ring. Once you have made your pendulum you should purify it.
Fill a clear bowl with fresh pure water. Say a cleansing prayer : "Purge me with hyssop, and I shall be clean, Wash me, and I shall be whiter than snow, Create in me a clean heart, And renew a right spirit within me".
Dip the crystal and thread into the water and leave for a few minutes.
On the night of a full moon place the pendulum and thread in the moonlight and leave for several hours. Never allow your pendulum to be placed in direct sunlight.
