The first of the several branches of consideration just enumerated relates to locality, and is to be exercised in the following manner:— In all eclipses of the Sun and Moon, and especially in such as are fully visible, the place in the zodiac, where the eclipse happens, is to be noted; and it must be seen what countries are in familiarity with that place, according to the rules laid down regarding the quadrants and the triplicities; and in like manner it must be observed what cities are under the influence of the sign in which the eclipse happens; either by means of the ascendant, and the situations of the luminaries at the time of their foundation, or by means of the mid-heaven of their kings or governors, actually ruling at the time of the eclipse; although such time may be subsequent to the building of the said cities.
