To return to our Vernal Equinox. Let us suppose that the Equator and Ecliptic of the sky, at the Spring season, are represented by two lines Eq. and Ecl. crossing each other at the point P. The Sun, represented by the small circle, is moving slowly and in its annual course along the Ecliptic to the left. When it reaches the point P (the dotted circle) it stands on the Equator of the sky, and then for a day or two, being neither North nor South, it shines on the two terrestrial hemispheres alike, and day and night are equal. BEFORE that time, when the sun is low down in the heavens, night has the advantage, and the days are short; AFTERWARDS, when the Sun has travelled more to the left, the days triumph over the nights. It will be seen then that this point P where the Sun's path crosses the Equator is a very critical point. It is the astronomical location of the triumph of the Sungod and of the arrival of Spring. How was this location defined? Among what stars was the Sun moving at that critical moment? (For of course it was understood, or supposed, that the Sun was deeply influenced by the constellation through which it was, or appeared to be, moving.) It seems then that at the period when these questions were occupying men's minds--say about three thousand years ago--the point where the Ecliptic crossed the Equator was, as a matter of fact, in the region of the constellation Aries or the he-Lamb. The triumph of the Sungod was therefore, and quite naturally, ascribed to the influence of Aries. THE LAMB BECAME THE SYMBOL OF THE RISEN SAVIOR, AND OF HIS PASSAGE FROM THE UNDERWORLD INTO THE HEIGHT OF HEAVEN. At first such an explanation sounds hazardous; but a thousand texts and references confirm it; and it is only by the accumulation of evidence in these cases that the student becomes convinced of a theory's correctness. It must also be remembered (what I have mentioned before) that these myths and legends were commonly adopted not only for one strict reason but because they represented in a general way the convergence of various symbols and inferences.
