This was manifestly not one of the common stars of Heaven. First, because none of the stars moves in this way, from east to south, and such is the situation of Palestine with respect to Persia. Secondly, from the time of its appearance, not in the night only, but during the day. Thirdly, from its being visible and then again invisible; when they entered Jerusalem it hid itself, and then appeared again when they left Herod. Further, it had no stated motion, but when the Magi were to go on, it went before them; when to stop, it stopped like the pillar of cloud in the desert. Fourthly, it signified the Virgin’s delivery, not by being fixed aloft, but by descending to earth, shewing herein like an invisible virtue formed into the visible appearance of a star.
