It’s a very brief summary. Rather than complaining you would do better to elaborate and and educate.

From the encyclopaedia Britanica it says:

> magus, plural Magi, member of an ancient Persian clan specializing in cultic activities. The name is the Latinized form of magoi (e.g., in Herodotus 1:101), the ancient Greek transliteration of the Iranian original. From it the word magic is derived.
