You’ve probably heard they weren’t really kings, but the wise men or magi had some impressive royal connections. Far from being one-off royal visitors to the infant Jesus, the magi had a long history of involvement with monarchy, crossing paths with illustrious kings including Cyrus the Great of Persia, Alexander the Great and the Roman Emperor Nero.
Originally a tribe of the Medes who lived in Northern Iran 600 years before Jesus’ birth, the Persian magi were hereditary priests. Writing around 425BCE, Greek historian Herodotus tells us how these magi became known throughout the ancient Middle East for their ability to interpret dreams and knowledge of the stars. They were followers of the Zoroastrian religion, and were responsible for the holy fires central to Zoroastrian worship.
To the Greeks, the Zoroastrians and the magi were exotic objects of fascination. Many later Greek written philosophical and occult works claimed Zoroaster (or Zarathustra) as their author. Much like some twentieth century Western conceptions of Hinduism and Buddhism, the Greek and Roman conceptions of Persian religion often had only a passing resemblance to the original. This may have included the "mystery cult" of Mithras that would become popular throughout the Roman Empire in the first century. This also means that references to 'magi' may not refer to the Persian magi, but to other astrologers or dream interpreters who lived to the east of the Mediterranean.
A hundred years before Herodotus, we find the first mention of magi in the bible, in the Book of Daniel. This was the period of Jewish exile and captivity in Babylon. Jehoikim, King of Judea and descendent of Kings David and Solomon, was defeated in battle and killed by Nebuchadnezzar II of Babylon. Jerusalem and its temple were destroyed, and many Judean nobles were taken as prisoners. Daniel was one of these hostages and is taken to the Babylonian court, where God gives him the ability to interpret the king’s dreams. Impressed by his abilities, Nebuchadnezzar puts Daniel in charge over all his wise men. It’s unclear what relationship these Babylonian ‘magi’ had with the Medean ones, but strong Medean influence on the Babylonian court suggests that the Babylonian wise men could well have included Zoroastrian magi.
Daniel remained in the Babylonian court, until the Babylonians were invaded by Cyrus the Great, who allowed the Jews to return from exile and to begin restoring Jerusalem.
Cyrus' Persian Empire lasted for two hundred years, until it was invaded by Alexander the Great and his army in 331BCE. Alexander sought the advice of magi, but had many of them violently killed and extinguished their holy fires when he razed the Persian capital, Persepolis in revenge for the Persian destruction of the Acropolis by Xerxes 150 years earlier. Alexander’s Greek successors were characterised by bloody rivalries and in-fighting and were later overthrown by the Parthian empire, which would become Rome’s most formidable rival to the east. The magi consolidated their king-making reputation during the Parthian period, with a council of magi (the Megistanes) responsible for choosing Parthian kings.
