Note. The reformation of the Zodiac, and the difference between the old reckoning by actual constellations and the new one by geometrical compartments, named after Signs that have since shifted their places in the sky, has been the cause of so much confusion, especially in the minds of our modern Gnostics, that the reader may be glad to see the very lucid explanation, which I owe to the great courtesy of the Astronomer Royal.

Royal Observatory, Greenwich, London, S.E.,

December 4th, 1912.

Dear Sir, — The only information that we have as to the way in which the ancient astronomers defined the borders of the constellations is derived from the catalogue of Claudius Ptolemy, circ. a.d. 130. This, no doubt, represents with fair correctness the arrangement of the constellations as recognised by Hipparchus in his catalogue now lost, of date circ. 129 b.c, and his catalogue again will have corresponded in this respect to the observations of Timocharis and Aristyllus made at Alexandria 150 years earlier, for it was from the comparison between his longitudes of the stars and those of his predecessors that Hipparchus discovered the fact and determined the amount of the precessional movement. We have no other means of ascertaining the original boundaries of the constellations.
