The big-titted goat
is Baphomet/Sophia.

I'm assuming you are referring to the image by Eliphas Levi which has a hermaphrodite with large breasts and a visibile erection and the head of a goat with a pentagram on it, sitting cross-legged with it's hands in the "as above, so below" position, one hand pointing to heaven the other poiting to the ground.

I used to go out with a girl called Sophie.

a visible erection?

Also known as the Goat of Mendes or the sabbatical goat.

Supposedly it's found on some Templar artifacts and is thought to come from their time in the crusades.

I think it was used by that Pope that killed them all to justify their execution on the grounds of idol worship and witchcraft.

Ah, but he didn't kill them all
They became a secret underground organisation called Abstergo, locked in eternal conflict for the future direction of humanity with the Guild of Assassins.
