How You Will Be Pwnd
As you can see my friend, you have been owned.
How was he? What he said was perfectly valid, or mostly so. The connection between Magus and the Magi is that Magus (latinized from Magos, which is Greekified for some persian word, probably Majus or something like that); plural, the Greeks said it Magoi, which became Magi.
Oh, and Wikipedia sucks. Don't trust it. Ever. Someone I know once put in an entry on the Samurai that the last of their number was Tomachiro Cruze, and it stayed up for a month. It is horridly unreliable. Not unless you know it yourself to be true.
However, looking over it, at least the Greek part is right. Magoi apo anatolon indeed means 'Wise-men from the East'. (though, literally, anatolon is what we'd call Anatolia, and that's Turkey; the name means 'rising... ' something or other. Not stars, but maybe firmament.) But really... don't trust Wiki for anything serious. My father was looking for things on Paul Gerhardt there, and it said that the Swedes dropped bombs on his village. The guys lived in the 1600s for goodness sake!
WAIT! HOLD EVERYTHING, I FOUND A MISTAKE THERE!
Magoi is NOT neutral in gender. If it were, singular would be Magon, and plural Maga. Magoi is standard second-declension plural masculine. I defenitely denotes a male set. See? A mistake. A minor one, but a mistake nonetheless... but it stands out like an eyesore now that I see it.
