There is also a similar story about Callisto: that she turned into a bear while out hunting.
But I would say that she, too, came upon a thicket where there happened to be a bear, and it devoured the huntress entirely. The other hunters, who had seen her enter but not emerge, said that the girl had become a bear.
They say that Europa, the daughter of Phoinix, travelled across the sea from Tyre to Crete, riding a bull. But I don’t think that a bull – or even a horse – could swim across such an expanse of open water. And nor would a girl climb up onto the back of a wild bull: if Zeus had wanted Europa to go to Crete, he would have found a better way to get her there.
The truth is as follows. A man from Knossos called Tauros [‘Bull’] was waging war around Tyre. He ended up carrying off many girls – and among them was the king’s daughter, Europa. And so people would say, Tauros has taken Europa, the daughter of the king, and gone off with her!
And from these events, the myth was fabricated.
