How to proceed in geomancy.

Bartholomew of Parma tells us that the art of geomancy originated from God and was taught to the sons of Noah by an angel who took on human form before the time of the flood. Whoever intends to practice that art should be “a friend of God” and a good man of praiseworthy life. No one should make use of it without real necessity of knowing the future and geomancers should beware of persons who try to catch them in error by asking questions about sure things. On the other hand, in certain cases one may ask questions for another person, and even without his knowledge, and questions may be put at any time and place, for the art of geomancy is simple and easy of operation. The only instrument needed is something to make a series of points or marks with. These dots should be set down in four rows like the four fingers of a hand, but at random without noting how many dots one puts in each row or how long the row is.[2666] These four rows indicate the elements, points of the compass, and so on. Next one cancels the points in each line, cancelling two at a time until only one or two points remain in each line. When this is done we have one of the following sixteen possible geomantic figures, which I have indicated numerically rather than graphically: 2121, 2212, 1211, 1222, 2111, 2222, 2112, 2211, 1212, 2122, 1121, 2221, 1112, 1111, 1221, 1122. Of these the first eight are favorable, the last eight are unfavorable. They bear such names as gain, white, childhood, joy, head (acquisitio, albus, pueritia, laetitia, caput). The first inventors of the art are supposed to have worked out these figures “with great ingenuity and subtlety” from careful observations of the stars and of the virtues of the sky. Hence these figures have the property of signifying much concerning the future. Each is associated with some particular sign of the zodiac and with one of the planets. Also with a day, month, color, odor, taste, stone, tree, metal, and human type.[2667]

Questions answered by geomancy.

Among the questions which geomancy undertakes to answer are how long one will live, whether one will better one’s present position, whether one should enter the clergy or remain a layman, whether a journey will be dangerous, whether a rumor is true or false, whether to buy or not, whether the year will be a fertile one, and concerning gain and loss, hidden treasure, the condition of a city or castle, and which side is stronger in a war. Whether a child will be born or not, of what sex it will be, and whether it is legitimate or a bastard. Which of two magistrates is superior in wisdom, whether a scholar can by study become an honor to the convent or not, whether the soul of some dead person is in paradise or before the doors of paradise or in purgatory or in hell. In answering such questions the figure found by chance from the points is compared with and related to figures appropriate to the person inquiring and the thing sought, and a decision is rendered according as enmity or friendship is found to exist between them. In determining this the figures are reduced to terms of the twelve signs of the zodiac, and the astrological aspects are thus investigated.
