dinal point, which by the inclination of the heavens is situated under the Earth, there ate
other constellations revolving that are unseen, never rising above the Earth; therefore their
appearances, on account of the intervention of the Earth, are unknown. Of this the star
Canopus is a proof, which is not known in these countries, otherwise than by the reports of
the merchants who travel to the extreme parts of Egypt, and near to the utmost limits of the
Earth.
I have thus treated of the revolutions of the heavens around the Earth, of the twelve signs,
and the disposition of the northern and southern constellations, as they are seen; because, by
the rotation of the heavens, the contrary course of the Sun through the signs, and the equi-
noctial shadows of gnomons, the construction of the anallemnas is to be found. As for the
other part of astrology, concerning the influence of the twelve signs, the five planets, and the
Sun and Moon, upon human life, it is to be left to the Chaldeans, to whom belongs the
science of genetbliologia, so that they can discover, by the aspects of the stars, both the past
and the future. The accounts of their discoveries, which they have left in writing, prove
their judgment and ingenuity, and what great men the nation of the Chaldeans has produced.
Firstly Berosus, who settled in the island and city of Coos, and there established a school.
Afterward came Antipater and Achinapolus, who left a treatise on the art of Genethliologia,
not from the birth, but from the conception. Of natural things, Thales the Milesian, Anaxa¬
goras the Clazomenian, Pythagoras the Samian, Zenophantes the Colophonian, and Demo-
critus the Abderite, have written; and have left their doctrines concerning the causes by which
things are governed, and how they produce their effects.
The discoveries of these men were prosecuted by Eudoxus, Eudæemon, Callistus, Melo,
Phillippus, Hipparchus, Aratus, and others, who by astrology, and the use of the parapeg-
matum, discovered the rising and setting of the stars, and the indications of the weather; and
have left them explained to posterity. The knowledge of such men is revered by mankind;
for so great is their judgment, that even, like divinities, they pronounce beforehand the
weather that fhall afterward happen; wherefore these things ought to be committed to their
care and application.

Pliny, b. 2. ch. 70, observes, that it is not seen in Italy,
but is just seen at Rhodes.
(8*) The science of foretelling future events in the
lives of mankind, and the state of the weather.
(9') An island in the Archipelago, near Rhodes.

opinion of some; according to others, a bras table con¬
