Ha!! New Perunology
If the key date for Alexander's champagne was 330 BC,
I'd say that the key date in Alexander's
life was when he visited the oracle of Siwa, Egypt, some years earlier.
There, Alexander asked him about the assassins of his father,
and the oracle answered that His father is not someone that a man can kill -meaning that it was Zeus.
This was a turning point to the life of Alexander, and from there on, he started being weird...
Some years after he killed two of his best friends, and had a great general killed as well.
It has to be said that the mother of Alexander was an oracle /bacchante of Dionysos
and it was her that advised Alexander to visit Zeus' Oracle in Siwa oasis
