But to us it seems not inappropriate to speak briefly of the Chaldaeans of Babylon and of their antiquity, that we may omit nothing which is worthy of record.
Now the Chaldaeans, belonging as they do to the most ancient inhabitants of Babylonia, have about the same position among the divisions of the state as that occupied by the priests of Egypt; for being assigned to the service of the gods they spend their entire life in study, their greatest renown being in the field of astrology. But they occupy themselves largely with soothsaying as well, making predictions about future events, and in some cases by purifications, in others by sacrifices, and in others by some other charms they attempt to effect the averting of evil things and the fulfilment of the good.
They are also skilled in soothsaying by the flight of birds, and they give out interpretations of both dreams and portents. They also show marked ability in making divinations from the observation of the entrails of animals, deeming that in this branch they are eminently successful. The training which they receive in all these matters is not the same as that of the Greeks who follow such practices.
For among the Chaldaeans the scientific study of these subjects is passed down in the family, and son takes it over from father, being relieved of all other services in the state. Since, therefore, they have their parents for teachers, they not only are taught everything ungrudgingly but also at the same time they give heed to the precepts of their teachers with a most unwavering trust. Furthermore, since they are bred in these teachings from childhood up, they attain a great skill in them, both because of the ease with which youth is taught and because of the great amount of time which is devoted to this study.
Now, as the Chaldaeans say, the world is by its nature eternal, and neither had a first beginning nor will at a later time suffer destruction; furthermore, both the disposition and the orderly arrangement of the universe have come about by virtue of a divine providence, and to‑day whatever takes place in the heavens is in every instance brought to pass, not at haphazard nor by virtue of any spontaneous action, but by some fixed and firmly determined divine decision.
And since they have observed the stars over a long period of time and have noted both the movements and the influences of each of them with greater precision than any other men, they foretell to mankind many things that will take place in the future.
But above all in importance, they say, is the study of the influence of the five stars known as planets, which they call “Interpreters” when speaking of them as a group, but if referring to them singly, the one named Cronus by the Greeks, which is the most conspicuous and presages more events and such as are of greater importance than the others, they call the star of Helius, whereas the other four they designate as the stars of Ares, Aphrodite, Hermes, and Zeus, as do our astrologers.
The reason why they call them “Interpreters” is that whereas all the other stars are fixed and follow a singular circuit in a regular course, these alone, by virtue of following each its own course, point out future events, thus interpreting to mankind the design of the gods. For sometimes by their risings, sometimes by their settings, and again by their colour, the Chaldaeans say, they give signs of coming events to such as are willing to observe them closely; for at one time they show forth mighty storms of winds, at another excessive rains or heat, at times the appearance of comets, also eclipses of both sun and moon, and earthquakes, and in a word all the conditions which owe their origin to the atmosphere and work both benefits and harm, not only to whole peoples or regions, but also to kings and to persons of private station.
Under the course in which these planets move are situated, according to them, thirty stars, which they designate as “counselling gods”; of these one half oversee the regions above the earth and the other half those beneath the earth, having under their purview the affairs of mankind and likewise those of the heavens; and every ten days one of the stars above is sent as a messenger, so to speak, to the stars below, and again in like manner one of the stars below the earth to those above, and this movement of theirs is fixed and determined by means of an orbit which is unchanging for ever.
Twelve of these gods, they say, hold chief authority, and to each of these the Chaldaeans assign a month and one of the signs of the zodiac, as they are called. And through the midst of these signs, they say, both the sun and moon and the five planets make their course, the sun completing his cycle in a year and the moon traversing her circuit in a month.
Each of the planets, according to them, has its own particular course, and its velocities and periods of time are subject to change and variation. These stars it is which exert the greatest influence for both good and evil upon the nativity of men; and it is chiefly from the nature of these planets and the study of them that they know what is in store for mankind.
And they have made predictions, they say, not only to numerous other kings, but also to Alexander, who defeated Darius, and to Antigonus and Seleucus Nicator who afterwards became kings, and in all their prophecies they are thought to have hit the truth.
Moreover, they also foretell to men in private station what will befall them, and with such accuracy that those who have made trial of them marvel at the feat and believe that it transcends the power of man.
Beyond the circle of the zodiac they designate twenty-four other stars, of which one half, they say, are situated in the northern parts and one half in the southern, and of these those which are visible they assign to the world of the living, allow those which are invisible they regard as being adjacent to the dead, and so they call them “Judges of the Universe.”
And under all the stars hitherto mentioned the moon, according to them, takes her way, being nearest the earth because of her weight and completing her course in a very brief period of time, not by reason of her great velocity, but because her orbit is so short.
They also agree with the Greeks in saying that her light is reflected and that her eclipses are due to the shadow of the earth. Regarding the eclipse of the sun, however, they offer the weakest kind of explanation, and do not presume to predict it or to define the times of its occurrence with any precision.
Again, in connection with the earth they make assertions entirely peculiar to themselves, saying that it is shaped like a boat and hollow, and they offer many plausible arguments about both the earth and all other bodies in the firmament.
This point a man may fittingly maintain, that the Chaldaeans have of all men the greatest grasp of astrology, and that they bestowed the greatest diligence upon the study of it.
But as to the number of years which, according to their statements, the order of the Chaldaeans has spent on the study of the bodies of the universe, a man can scarcely believe them; for they reckon that, down to Alexander’s crossing over into Asia, it has been four hundred and seventy-three thousand years, since they began in early times to make their observations of the stars.

NovoScriptorium: It is rather obvious from the above stories that the Chaldeans were not scientifically occupied with Astronomy. Instead, “occult Astrology” would be a better description of their occupation. The Chaldeans were incapable of predicting eclipses of the Sun, as Diodorus writes. Let’s remember here e.g. Thales of Miletos (7th-6th cen. BC) who predicted at least two different eclipses of the Sun. The difference between the two civilizations becomes apparent. It is a suprise -and surely a rape of Logic- when studiers of the Ancient Tradition come out and claim that the ancient Greeks learned their Astronomy from the Chaldeans. As we have seen in previous posts (e.g. here), not only the Greeks had adequate -and surely more scientific than the Chaldeans- astronomical knowledge, but in the most basic texts of their Ancient Tradition (e.g. Homer, Hesiod, Orphic Hyms), astronomical references are countless and, sometimes, very informative, too, for events that took place thousands of years ago. This implies that they were indeed observing the skies for quite a long time. But how much back in Time, we cannot possibly know.
