Don't you mean astronomy?
As an Australian, I always thought they were Tom, Dick and Harry.
On a more serious note, after reading Fr. Longenecker's post, I'm guilty of both counts for not having any idea who they were - the first was that it seemed unproveable, lost in the mists of history, and the other was that I wondered if the story was true, a quasi-historical embellishment, although Herod would have needed a reason to kill the infants, relying on innocent witnesses with enough credibility to take them seriously.
But even if Fr. Longenecker is correct, the fact remains his theory is just that - a theory. It may be a plausible theory, it may even be the correct theory - but if we don't even know for certain who actually penned the Gospels, we're not likely to be able to pinpoint who the mysterious Magi were.
They're in the story, but they're just as much unknown to us as the shepherds who saw the angels and the Holy Family, and for that matter the animals in the barn. They were there, but we have no idea who they were.
I suppose one day we'll find out, but we'll have to die first.
