...Head, rule the Earthly Triplicity original: "Triplicity"; a grouping of three or four astrological signs or figures belonging to the same element (Fire, Earth, Air, Water). White original: "Albus", Loss original: "Amissio", and Sorrow original: "Tristitia" make up the Airy Triplicity. The Way original: "Via", The People original: "Populus", and Red original: "Rubeus", along with the Dragon's Tail original: "Cauda Draconis" and Gain original: "Acquisitio", rule the Watery Triplicity. This order is determined according to the sequence or manner of the signs.

However, if anyone wishes to arrange these triplicities according to the natures of the planets and the figures themselves, let them observe this rule: Greater Fortune original: "Fortuna major", Red, The Boy original: "Puer", and Loss make up the Fiery Triplicity. Lesser Fortune original: "Fortuna minor", The Girl original: "Puella", Joy original: "Laetitia", and Conjunction original: "Conjunctio" make up the Triplicity of the Air. Gain, the Dragon's Tail, The Way, and The People govern the Watery Triplicity. Finally, the Earthly Triplicity is ruled by Prison original: "Carcer", Sorrow, White, and the Dragon's Head original: "Caput Draconis". This method is preferred over the first one we set forth, because it is established according to the rule and manner of the signs.

This arrangement is also far more accurate and rational than the one commonly original: "vulgarly" used, which is described in this way: the Fiery Triplicity consists of the Dragon's Tail, Lesser Fortune, Loss, and Red. The Airy Triplicity consists of Gain, Joy, The Boy, and Conjunction. The Watery Triplicity consists of The People, The Way, White, and The Girl. And the Dragon's Head, Greater Fortune, Prison, and Sorrow belong to the Earthly Triplicity.

They likewise distribute these figures among the twelve signs of the Zodiac original: "Zodiack" in this manner: Gain is assigned to Aries; Fortune (both Greater and Lesser) is assigned to Taurus; Joy to the sign of Gemini; The Girl and Red to Cancer; White is assigned to Leo; The Way to Virgo; the Dragon's Head and Conjunction to Libra; The Boy is assigned to Scorpio; Sorrow and Loss are assigned to Sagittarius original: "Sagittary"; the Dragon's Tail to Capricorn; The People to Aquarius; and Prison is assigned to the sign of Pisces.

Now we come to speak of the method of projecting or setting down these figures, which is as follows: we set down the points according to their sequence in four lines, from the right hand toward the left, and we do this in four courses The practitioner makes four rows of random dots to generate a single geomantic figure based on whether each row is even or odd. This will result in four figures made in four separate lines, based on whether there is an even or uneven number of marks in each individual line. These four figures are usually called the Mothers original: "Matres", which "bring forth" the rest, filling up and completing the entire chart original: "Figure".
