…that this star was not of the common sort, or rather not a star at all, as it seems at least to me, but some invisible power transformed into this appearance, is in the first place evident from its very course. For there is not, there is not any star that moves by this way, but whether it be the sun you mention, or the moon, or all the other stars, we see them going from east to west; but this was wafted from north to south; for so is Palestine situated with respect to Persia.
In the second place, one may see this from the time also. For it appears not in the night, but in mid-day, while the sun is shining; and this is not within the power of a star, nay not of the moon; for the moon that so much surpasses all, when the beams of the sun appear, straightway hides herself, and vanishes away. But this by the excess of its own splendor overcame even the beams of the sun, appearing brighter than they, and in so much light shining out more illustriously.
…[Later in the narrative] it did not, remaining on high, point out the place; it not being possible for them so to ascertain it, but it came down and performed this office. For ye know that a spot of so small dimensions, being only as much as a shed would occupy, or rather as much as the body of a little infant would take up, could not possibly be marked out by a star. For by reason of its immense height, it could not sufficiently distinguish so confined a spot, and discover it to them that were desiring to see it. And this any one may see by the moon, which being so far superior to the stars, seems to all that dwell in the world, and are scattered over so great an extent of earth,””seems, I say, near to them every one. How then, tell me, did the star point out a spot so confined, just the space of a manger and shed, unless it left that height and came down, and stood over the very head of the young child? And at this the evangelist was hinting when he said, “Lo, the star went before them, till it came and stood over where the young Child was.”
