ASTROLO´GIA

ASTROLO´GIA This word is employed by the best Latin writers (e. g. Cic. de Divin. 2.42, 87; de Orat. 1.16, 69) to denote astronomy in general, for which astronomia does not occur earlier than Seneca. In Greek, ὰστρολογία is the [p. 1.213]more common term, and is the only one used in the genuine works of Aristotle. But Xenophon (Xen. Mem. 4.7, 4 and 5) and Theophrastus use both αστρολογία and ἀστρονομία in the same sense. In the present article, however, we employ the word in the sense in which it is used in the Christian Fathers, for what is strictly termed judicial astrology, and treat of astronomy under ASTRONOMIA

At a period far beyond the records of authentic history a belief arose, which still prevails unshaken in the East, that a mysterious but close connexion subsisted between the relative position and movements of the heavenly bodies and the fate of man. In process of time it was maintained that the fortunes of each individual throughout life depended upon the aspect of the sky at the moment of his birth, and especially upon the star which was rising above the horizon at the instant when he saw the light, and upon those which were in its immediate vicinity (conjunctae), or removed from it by a sixth, a fourth, or a third part of a great circle of the sphere; or, finally, upon those which were at the apposite extremity of the same diameter (oppositae). Few doubted that by observation and deep study persons might acquire the power of expounding these appearances, that the destiny of the child might be predicted with certainty by those who were skilled to interpret the language of the stars, and that the result of any undertaking might be foretold from the aspect of the firmament when it was commenced. Hence a numerous and powerful class of men arose who were distinguished by various designations. From the country where astronomy was first studied, and their science was first developed, they were called Chaldaei or Babylonii; from observing the stars, astronomi, astrologi, planetarii; from employing diagrams such as were used by geometricians, mathematici; from determining the lot of man at his natal hour, genethliaci; from dealing with the effects (ἀποτελέσματα) of the stars, ἀποτελεσματικοί: while their art was known as ἀστρολογία, μετεωρολογία, γενεθλιαλογία, ἀποτελεσματική, Ars Chaldaeorum, Mathesis, or, from the tables they consulted, πινακική. Their calculations were termed Babylonii numeri, Χαλδαίων μέθοδοι, Χαλδαίων ψηφῖδες, Rationes Chaldaicae; their responses when consulted, Chaldaeorum monita, Chaldaeorutm natalicia praedicta, Astrologorum praedicta.

The stars and constellations to which attention was chiefly directed were the planets and the signs of the zodiac, some of which were supposed to exert uniformly a benign influence (ἀγαθοποιοὶ ἀστέρες), such as Venus, Jupiter, Luna, Virgo, Libra, Taurus; others to be uniformly malign (κακοποιοὶ ἀστέρες), such as Saturnus, Mars, Scorpio, Capricornus; others to be doubtful (ἐπίκοινοι ἀστέρες), such as Mercurius. By the combination and conjunction (συνδρομή, constellatio) or opposition, however, of those benign with those malign, the power of the latter might be neutralised or even reversed, and a most happy horoscope be produced, as in the case of Augustus, who was born under Capricornus (Suet. Aug. 94), and hence that figure frequently appears on his medals. For the sake of expediting calculations, the risings, settings, movements, and relative positions (ortus, occasus, motus, viae, discessiones, coetus, conventus, concursiones, circuitus, transitus, habitus, forma, positura, positus siderum et spatia) were carefully registered in tables (πίνακες, ἐφημερίδες). In so far as the planets were concerned, it was of especial importance to note through what sign of the zodiac they happened to be passing, since each planet had a peculiar sign, called the domus or house of the planet, during its sojourn in which it possessed superior power. Thus Libra, Capricornus, and Scorpio were respectively the houses of Venus, Saturn, and Mars.

The exact period of birth (hora genitalis) being the critical moment, the computations founded upon it were styled γένεσις (genesis or genitura), ὡροσκόπος (horoscopus), or simply θέμα, and the star or stars in the ascendant sidus natalicium, sidera natalicia, or sometimes ὡροσκόπος.

The Chaldaean astrology was unknown in Greece until after the conquests of Alexander, although Eudoxus, a younger contemporary of Plato, is said to have warned his countrymen not to place faith in it (Cic. de Div. 2.4. 2, 87). Euripides (Frag. 485 Dind.) describes Hippo, the daughter of Chiron, as predicting the future from the risings of stars: but Archdeacon Hare (Philol. Mus. 1.25) thinks that this referred only to predictions of the weather. This limitation will not apply to the language of Plato (Timaeus, p. 40 D) about divination from the movements of the planets (Lewis, Astr. of the Anc. p. 295). The first Chaldaean who practised astrology in Greece is said to have been Berosus (Vitr. 9.7), who lived about B.C. 340-270. After this time it passed into general acceptance, especially among the Stoic philosophers: and Panaetius, in the second century, who rejected it, mentioned Anchialus and Cassander, two contemporary astronomers, as standing alone in sharing his views (Cic. de Div. 2.4. 2, 88). Astrologers by this time had found their way to Rome. The words de circo astrologos in Cic. de Div. 1.5. 8, 132, evidently belong, not to Ennius, as has sometimes been supposed, but to Cicero himself (cf. Ribbeck, Frag. Trag.2 p. 55): but Cato (de R. R. 5, 4) forbids his steward to consult “haruspicem, augurem, hariolum, Chaldaeum.”

In B.C. 139 C. Cornelius Hispallus, the praetor peregrinus, banished the Chaldaeans from the city, and ordered them to quit Italy within ten days (V. Max. 1.3.2). We read, however, of prophecies of the Chaldaeans given to Sulla, Pompeius, Crassus, and Caesar; and Cicero speaks of L. Tarutius Firmanus, the friend of Varro, as “in primis Chaldaicis rationibus eruditus” (de Div. 2.47, 98). In B.C. 33 they were again banished from the city by M. Agrippa, who was then aedile (D. C. 49.1). Another severe ordinance was levelled by Augustus against this class (D. C. 65.1, 66.25), but the frequent occurrence of such phrases as “expulit et mathematicos” (Suet. Tib. 36), “pulsis Italia mathematicis” (Tac. Hist. 2.62), in the historians of the empire, prove how firm a hold these pretenders must have obtained over the public mind, and how profitable the occupation must have been which could induce them to brave disgrace, and sometimes a cruel death (Tac. Ann. 2.32). Notwithstanding [p. 1.214]the number and stringent character of the penal enactments by which they were denounced, they appear to have kept their ground, and, although from time to time crushed or terrified into silence, to have revived with fresh vigour in seasons of confusion and anarchy, when all classes of the community, hanging in suspense between hope and fear, were predisposed to yield to every superstitious impulse. It must be remembered also, that the most austere princes did not disdain, when agitated by doubts or excited by ambitious longings, to acquire the principles of the art and to consult its professors, as we may perceive, not to multiply examples, from the well-known story of Tiberius and Thrasyllus (Tac. Ann. 6.20, 21). Hence Tacitus, after recounting the high promises by which the “mathematici” stimulated Otho to assume the purple, adds in a tone of sorrowful resignation, “genus hominum potentibus infidum, sperantibus fallax, quod in civitate nostra et vetabitur semper et retinebitur.” (See Cic. de Div. 2.4. 2 ff.; Gel. 14.1 ; Hor. Carm. i. 11, 2, 2.17, 17; Pers. 5.46; Juv. 3.43, 7.194, 10.94 (with Mayor's note), 14.248, 6.553-581; Tac. Ann. 2.27, 32, 3.22, 4.58, 6.20, 12.22, 52, 68, 16.14; Hist. 1.22, 2.62; Suet. Tib. 14, 36, Vitell. 14, Nero 40, Galb. 4; Gel. 1.9; D. C. 49.43, 56.25, 57.15, 65.1; Zonar. ii. p. 142; Lips. Excurs. vii. ad Tac. Ann. ii. ; Jani, Excurs. ad Hor. Carm. 2.17.17; Ruperti, Not. ad Tac. Ann. 2.27. For the penal enactments, see Rein, Das Criminalrecht der Römer, p. 901, &c. Leipzig, 1844; Becker, Handbuch der röm. Alterth. 4.100-102 ; and on the general question, Lewis, Astron. of the Ancients, pp. 292-303. Those who would acquire a knowledge of the technical details of astrology, as practised by the ancients, must peruse the Latin poem of Manilius, the treatise of Julius Firmicus, and the Greek works of Manetho, Paulus, and Ptolemy.)
