We are informed by Fabricius, that Marsham, in Canone Chron. p. 477, has eruditely collected many things pertaining to Petosiris, and Necepso king of Egypt, from the most ancient writers on judicial astrology. We likewise learn from Fabricius, that Necepso, to whom Petosiris wrote, as being coeval with him, is believed to have flourished about the year 800 of the Attic æra, i. e. about the beginning of the Olympiads. He is praised by Pliny, by Galen, ix. p. 2. De Facultat. Simplicium Medicament., and from him by Aetius. [c] _Page 56._—Proclus in Tim. lib. iv. p. 277, informs us, that the Chaldeans had observations of the stars, which embraced whole mundane periods. What Proclus likewise asserts of the Chaldeans is confirmed by Cicero in his first book on Divination, who says that they had records of the stars for the space of 370,000 years; and by Diodorus Siculus, Bibl. lib. xi. p. 113, who says, that their observations comprehended the space of 473,000 years. Plato, in the Timæus, speaking of this greater apocatastasis, says: “At the same time, however, it is no less possible to conceive, that the perfect number of time will then accomplish a perfect year, when the celerities of all the eight periods being terminated with reference to each other, shall have a summit, as they are measured by the circle, of that which subsists according to the same and the similar [i. e. according to the sphere of the fixed stars].” On this passage, Proclus, in his Commentary, observes as follows: “The whole mundane time measures the one life of the universe, according to which all the celerities are terminated of the celestial and sublunary circles. For in these also there are periods, which have for the summit of their apocatastasis the lation of the circle of _the same_ [i. e. of the sphere of the fixed stars]. For they are referred to this as to their principle, because it is the most simple of all, since the apocatastases are surveyed with reference to the points of it. Thus, for instance, all of them make their apocatastasis about the equinoctial point[47], or about the summer tropic; or though the joint apocatastasis should not be considered to be according to the same point, but with reference to the same, when, for instance, rising or culminating, yet all of them will have with reference to it a figure of such a kind. For now the present order is entirely a certain apocatastasis of all the heavenly bodies, yet the configuration is not seen about the same, but with reference to the same point. Once, however, it was about the same, and according to one certain point, at which if it should again take place, the whole of time will have an end. One certain apocatastasis likewise seems to have been mentioned; hence it is said that Cancer is the horoscope of the world, and this year is called Cynic, or pertaining to the Dog, because, among the constellations, the splendid star of the Dog rises together with Cancer.
