It is a bit weird that the headlines around this find are mostly being phrased like that. We studied both in school, and I had assumed they were both pretty well known.

I guess for a headline-writer, though, "Alexander the Great" has near-universal recognition, while "Philip of Macedon" doesn't have enough to assume that a general audience will have their eye caught by the headline. So it ends up with this slightly dumbed-down phrasing.
