How many Magi were there?

The Holy Bible is the inspired, inerrant, infallible Word of the Living God.

In the second chapter of both gospel books of Matthew and Luke, we are introduced to the circumstances surrounding the birth of Jesus Christ. The wise men or Magi are introduced to the account of this event. What is so significant about these individuals?

These wise men from the East are universally accepted as astronomers and mathematicians from what was once the Babylonian and Persian empires. The Magi from the account of the birth of Jesus were not numbered as just three individuals nor were they "kings". They were king-makers. It never states the amount of wise men that came to Herod or the time of Jesus' birth. The three gifts of frankincense, gold, and myrrh that were brought to present to the King of the Hebrews are the clue into how there became "three Magi". The thought is that each wise man brought a gift; three gifts, three wise men. However, historic records note that Magi never traveled alone and usually in large groups otherwise known as caravans.

Why would ONLY three Magi travel on a three-month journey by camel to such a significant event in a far away land?
