Catena Aurea · Matthäusevangelium 2
Then Herod, when he had privily called the wise men, enquired of them diligently what time the star appeared. And he sent them to Bethlehem, and said, Go and search diligently for the young Child; and when ye have found Him, bring me word again, that I may come and worship Him also. When they had heard the king, they departed.
(non occ.) According to others, the star was first seen on the day of the nativity, and having accomplished its end, ceased to be. Thus Fulgentius says, “The Boy at His birth created a new star.” (Serm. de Epiph.) Though they now knew both time and place, he still would not have them ignorant of the person of the Child, Go, he says, and enquire diligently of the young Child; a commission they would have executed even if he had not commanded it.
