The Science of the Sand علم الرملArabic geomancy, from Baghdad to Darfur

A brass tray of smooth sand on an inlaid table in a lamp-lit desert tent at night, seven hollows pressed into the sand in rows of one, two, two and two.
The hollows in the sand make a real figure: rows of 1, 2, 2 and 2 dots, al-Laḥyān, the Bearded One. In Latin it was called Laetitia, Joy.

For a thousand years, from Morocco to Persia, people took their questions to the sand-diviner. He smoothed out a patch of sand, pressed rows of hollows with his finger without counting them, and turned them into four figures of one or two dots. From those four “Mothers” he built a chart of sixteen houses. The fifteenth, the Judge of the sand, gave the answer.

How to consult

  1. Think of your question. Type it in if you like; it stays on your device.
  2. Flip the four blocks four times. Each block lands showing one dot or two, and each flip makes one Mother, row by row from top to bottom. Or choose Tap the sand to make the Mothers the old way, with hollows in the sand counted off in pairs.
  3. The chart builds itself, right to left as Arabic is written. Read the Judge, the two Witnesses who stand above it, and the outcome. Tap any house to read its figure.
The story of the sand

The geomancers told that the angel Gabriel was the first to draw in the sand, and that he taught the prophet Idrīs (Enoch). The science passed from teacher to pupil, to a sage called Ṭumṭum the Indian, to Khalaf the Berber, and down to the great master al-Zanātī. Others gave the honour to Daniel.

Al-Zanātī explained why there are four Mothers: the world is made in fours. There are four elements, four seasons, four directions and four corners to a house, and the four rows of each figure stand for fire, air, water and earth.

Your question and answers stay on this device.

Your past answers
    How do we know?
    • ✔ The method. Ibn Khaldūn described it in 1377: sixteen rows of marks made without counting, cast out in pairs, four Mothers, and fifteen figures built from them, with a sixteenth from the first and fifteenth. Al-Zanātī's book, written before about 1230 and printed many times in Cairo, gives the same chart. The Judge always has an even number of dots, and you can check it here: it always does.
    • ✔ The figures. The sixteen dot patterns and their Arabic names come from al-Zanātī and from a sand-diviner described by Muḥammad al-Tūnisī, who lived in Darfur around 1800. His account was printed in French in 1845, and we checked every pattern against its pages.
    • ✔ The oldest dated witness. A brass geomancy machine made in Mosul in 1241/2 by Muḥammad ibn Khutlukh al-Mawṣilī, now in the British Museum, has dials for the Mothers and an omen for each figure. We give its omens in our own words, from Emilie Savage-Smith and Marion Smith's study (1980).
    • ≈ The sources don't always agree. The Gathering is good for al-Zanātī and bad on the brass machine; the Smooth Cheek is good for al-Zanātī and bad for the Darfur diviner. We show each voice under its own name, and the verdict follows al-Zanātī.
    • ≈ The blocks. The old way was the sand, or pen and paper. Flipping two-sided pieces gives the same one-or-two dots, as the Yoruba Ifá chain does in West Africa, but it is our convenience, not al-Zanātī's.
    • ✔ To Europe. In the 1100s the science was translated into Latin, and became geomantia. Each Arabic figure has a Latin twin: al-Ṭarīq, the Road, became Via, the Way.
    • ≈ Not everyone approved. Ibn Khaldūn and many religious scholars thought the sand could not truly see the unseen, and Islamic law often forbade this kind of fortune-telling. Al-Zanātī opened each reading with a verse of the Qurʾān; we do not use those verses here.
    • ✔ Our words. The English, the readings and the house names are our own. We have left out old meanings about illness and death, and softened two house names (7 and 8) for younger readers.
