Note 18 — PART I

The initial point of the Hindu Zodiac (see Plate III.) is about 9½ degrees to the west of the boundary line of the constellation Aries, as it is drawn on our celestial globes. One foot of Aries, however, extends beyond the boundary line, and touches a line drawn through the initial point of the Hindu Zodiac and the poles of the ecliptic. At page 132, the question of the date of the fixation of this initial point is discussed, and a high antiquity for it is claimed. There are many considerations which may lead us to the opinion that not only in India, but amongst the ancients generally, the first degree of the constellation coincided with the Hindu initial point, and not with the boundary line of the constellation, as it is now drawn. Greek and Latin authors, writing in the first century B.C., speak of the solstitial and equinoctial colures, as being “at the eighth degree of the Zodiac,” and these statements, which have caused modern commentators much perplexity (see Handbuch der Klassischen Alterthumswissenschaft; Zeitrechnung der Griechen und Römer, Unger), may be easily explained, if we realize that they, in all likelihood, counted the degrees of the Zodiac from the same initial point as that in use amongst Hindu astronomers, which in the first century B.C. was eight degrees to the west of the equinoctial point.
