CHAPTER II this starry phenomenon with Kepler to be real and well ascertainable by calculation, namely, as a conjunction of the Planets Jupiter and Saturn. That Matthew speaks only of a star (ἀστήρ), not a constellation (ἄστρον), need not trouble us, for the two words are not unfrequently confounded. The just named great astronomer, who was well acquainted with the astrology of his and former times, and who used it occasionally as a means for commending astronomy to the attention and respect of the laity, first conceived this idea when he observed the conjunction of the two planets mentioned at the close of the year 1603. It took place Dec. 17. In the spring following Mars joined their company, and in autumn 1604 still another star, one of those fixed star-like bodies (einer jener fixstern-artigen Körper) which grow to a considerable degree of brightness, and then gradually disappear without leaving a trace behind. This star stood near the two planets at the eastern foot of Serpentarius (Schlangenträger), and appeared when last seen as a star of the first magnitude with uncommon was premonitory and coincided with the conception of the birth of John the Baptist, Oct. 748, and that Kepler’s new star was Messiah’s star appearing a year later. splendor. From month to month it waned in brightness, and at the end of 1605 was withdrawn from the eyes which at that time could not yet be aided by good optical instruments. Kepler wrote a special work on this Stella nova in pede Serpentarii (Prague, 1606), and there he first set forth the view that the star of the Magi consisted in a conjunction of Saturn, Jupiter and some other extraordinary star, the nature of which he does not explain more fully.” Ideler then goes on to report (p. 404) that Kepler, with the imperfect tables at his disposal, discovered the same conjunction of Jupiter and Saturn a.u. 747 in June, August and December, in the sign of the Pisces; in the next year, February and March, Mars was added, and probably another extraordinary star, which must have excited the astrologers of Chaldaea to the highest degree. They probably saw the new star first, and then the constellation. Dr. Münter, bishop of Seeland, in 1821 directed new attention to this remarkable discovery, and also to the rabbinical commentary of Abarbanel on Daniel, according to which the Jewish astrologers expected a conjunction of the planets Jupiter and Saturn in the sign of the Pisces before the advent of the Messiah, and asked the astronomers to reinvestigate this point. Since then Schubert of Petersburg (1823), Ideler and Encke of Berlin (1826 and 1830), and more recently Pritchard of London, have verified Kepler’s calculations.
JESUS CHRIST 59 Ideler describes the result of his calculation (vol. II. 405) thus: I have made the calculation with every care .... The results are sufficiently remarkable. Both planets [Jupiter and Saturn] came in conjunction for the first time a.u. 747, May 20, in the 20th degree of Pisces. They stood then on the heaven before sunrise and were only one degree apart. Jupiter passed Saturn to the north. In the middle of September both came in opposition to the sun at midnight in the south. The difference in longitude was one degree and a half. Both were retrograde and again approached each other. On the 27th of October a second conjunction took place in the sixteenth degree of the Pisces, and on the 12th of November, when Jupiter moved again eastward, a third in the fifteenth degree of the same sign. In the last two constellations also the difference in longitude was only about one degree, so that to a weak eye both planets might appear as one star. If the Jewish astrologers attached great expectations to conjunction of the two upper planets in the sign of the Pisces, this one must above all have appeared to them as most significant.” In his shorter Lehrbuch der Chronologie, which appeared Berlin 1831 in one vol., pp. 424–431, Ideler gives substantially the same account somewhat abridged, but with slight changes of the figures on the basis of a new calculation with still better tables made by the celebrated astronomer Encke, who puts the first conjunction of Jupiter and Saturn a.u. 747, May 29th, the second Sept. 30th, the third Dec. 5th. See the full table of Encke, p. 429. We supplement this account by an extract from an article on the Star of the Wise Men by the Rev. Charles Pritchard, M.A., Hon. Secretary of the Royal Astronomical Society, who made a fresh calculation of the constellation in a.u. 747, from May to December, and published the results in Memoirs of Royal Ast. Society, vol. xxv., and in Smith’s “Bible Dictionary,” p. 3108, Am. ed., where he says: “At that time [end of Sept., b.c. 7] there can be no doubt Jupiter would present to astronomers, especially in so clear an atmosphere, a magnificent spectacle. It was then at its most brilliant apparition, for it was at its nearest approach both to the sun and to the earth. Not far from it would be seen its duller and much less conspicuous companion, Saturn. This glorious spectacle continued almost unaltered for several days, when the planets again slowly separated, then came to a halt, when, by reassuming a direct motion, Jupiter again approached to a conjunction for a third time with Saturn, just as the Magi may be supposed to have entered the Holy City. And, to
