The Magi are called "saints" for the first time in the writings of Archbishop Hildebert of Tours (1133). In the twelfth century their veneration spread over all of Europe. The authorities of the Church did not prohibit this cult, and Epiphany acquired the popular name of "Feast of the Three Holy Kings" in most countries of Europe.
The name Magi is not a Hebrew word, but of Indo-European origin, and means "great, illustrious." Saint Matthew mentioned the term without explanation because it was well known to the people of Palestine. The Magi originated in Media (Persia), and their caste later spread to other Oriental countries. They were a highly esteemed class of priestly scholars, devoting themselves not only to religion but also to the study of natural sciences, medicine, mathematics, astronomy, and astrology. In several countries they were members of the king's council.
