I am not sure, but I think you are correct, Humboldt. Pan is described in Greek mythology as half-goat half-man. So there is definitely a connection there.

Interestingly, goats are considered 'satanic' because of Dionysia (I think), the feast where they worship Dionysus, the god of wine and delights. In that feast, people wear goat-head masks and they drink until they are passed out drunk. In their drunken state they are so agressive that the term 'Holy Rage' is used to describe them.

I guess the sight of a large group of drunk Greeks dancing around in goat-head masks was enough to connect goats with evil.
