Well, of all things! A thread on the SDMB wherein astrological study is relevent! I swan! I offer the following:
There was, in fact, a extraordinary conjunction in the sign of Pisces, occuring in 4 b.c.e, in early spring, very close to the spring equinox. Sadly, such conjunctions are not visualy specatacular, it would appear as nothing more than several bright planets very close to each other. To create the effect that common myth gives to the star, it would almost have to be a supernovae in Jupiter’s orbit. The real thing, however, probably wasn’t that much to look at.
It would, however, would have been an event of great significance to a “wise man” of that time, who was very likely to be conversant in some form of astrological reckoning, most likely the Babylonian derived mathematics and symbology that survives in many forms still.
For if the wise men set on an overland journey of any distance, they would have been traveling some time. If they started thier journey “from the East {Babylon/Persia?}” when Jesus was born and they beheld a miraculous star, it would be weeks before they arrived. Yet according to the Scripture, they were Johnny on the spot! Note also, they were from some unnamed “east”, as if to say “not from around here”. Auslanders
Therefore, it is reasonable to assume they set out on thier journey quite some time before the actual birth of Jesus. What best accounts for this would be the assumption that the “wise men” were likely to be aware of the astrological significance of the time. How they might have guessed which direction to travel in, I have no clue.
The Poster does allege and aver that this opinion is offered for interesting conjecture only, and Poster will not be dragged herefrom into any debate whatsoever about the validity of astrology and related studies, or lack of validity thereof.
