By the 6th century, the wise men were referred to as kings in the popular imagination. The number of kings varied - usually being two, four, or twelve. They are usually referred to as Caspar, Melchior, and Balthasar. Furthermore, some people believe each of the wise men came from one of the three continents that were known of at the time of Christ's birth. He is believed to have come from Europe or Tarsus bearing the gift of myrrh.
Myrrh is the fragrant gum of certain plants which grew in Arabia and India.
It was imported by the Israelites for use in expensive perfumes and incense. It also had medicinal uses. Because it was believed to strengthen a child and get rid of worms, the gift of myrrh signifies Christ's mortality, and His roles of the Suffering Savior and the Great Physician. It both a Christmas and a Passion symbol. This drink was believed to lessen the pains of crucifixion.
