Thus, in all countries, certain respective peculiarities exist in regard to manners, customs and laws; and in each it is found that some portion of the inhabitants differs partially and individually from the usual habits and condition of their race. These variations arise similarly to the variations perceptible in the condition of the atmosphere; as, in all countries, the general state of whose atmosphere may be either hot, or cold, or temperate, certain districts are found to possess a particular temperature of their own, and to be more or less hot, or cold, by being more or less elevated than the general face of the country. So, likewise, certain people become navigators owing to their proximity to the sea, while others are equestrian, because their country is a plain; and others, again, become domiciliated by the fertility of their soil. And thus, in each particular climate, certain peculiar qualities are to be found, arising from the natural familiarity which it holds with the stars and the twelve signs. And although these qualities do not pervade it, in such a manner as to be necessarily exhibited by every individual native, yet they are so far generally distributed as to be of much utility in investigating particular events; and it is highly important to take at least a brief notice of them. CHAPTER III THE FAMILIARITY OF THE REGIONS OF THE EARTH WITH THE TRIPLICITIES AND THE PLANETS It has been already stated that there are four triplicities distinguishable in the zodiac. The first, composed of Aries, Leo, and Sagittarius, is the north-west triplicity; and Jupiter has chief dominion over it on behalf of its northern proportion; but Mars also rules with him in reference to the west. The second, consisting of Taurus, Virgo, and Capricorn, is the south-east; and in this triplicity Venus bears chief rule, in consequence of the southern proportion; but Saturn also governs with her in consideration of the east. The third, composed of Gemini, Libra, and Aquarius, is north-east; and Saturn is here the principal lord, in consequence of the eastern proportion; Jupiter, however, governs with him in reference to the north. The fourth triplicity is constituted of Cancer, Scorpio, and Pisces, and is south-west; it owns Mars as its principal ruler, in consideration of its western proportion; and, on behalf of the south, it is also governed by Venus. The four triplicities being thus established, the whole inhabited earth is accordingly divided into four parts, agreeing with the number of the triplicities. It is divided latitudinally by the line of the Mediterranean Sea, from the Straits of Hercules to the Issican Gulf, continued onwards through the mountainous ridge extending towards the east; and by this latitudinal division its southern and northern parts are defined. Its longitudinal division is made by the line of the Arabian Gulf, the Ægean Sea, Pontus, and the lake Mæotis; and by this line are separated its eastern and western parts.
