I have said, in the past, that the only way one can reconcile Enterprise with the established Trek Canon is to assume that it is, in fact, the 24th-Century equivalent of Sam Raimi's Hercules and Xena: fantasy shows with a vaguely historical setting, chock full of inaccuracies and anachronisms, enjoyed mostly for the cheesy humor value of being so damned B-movie bad.
I was right.
