Why is pure oxygen called O2 when oxygen is an element?

I don't know if anyone is interested but there would be more versions too. Solid oxygen (red oxygen) at high pressure used to be thought of as O4, tetraoxygen aka oxozone. But if you look at it with x-ray crystallography it's O8, octaoxygen. Cool huh
