The Bible tells us that wisemen or scholars saw a star which they took to be the sign of the birth of a new king. They followed the star and from their understanding of ancient prophecies they believed that they were looking for a child who would be the saviour of the world. They consulted with King Herod and eventually found the baby who was with Mary and Joseph. They were warned in a dream not to return to King Herod after they had found the baby and so they returned to their own country.
