The presence of a large Roman bath house already found in Nazareth shows that the claims of it being a Roman military camp site are not "unfounded".[/b]
It's unfounded because it doesn't logically follow that, on the basis of an unexcavated, not interdisciplanarily verifiable first century Roman bath-house that all of the sudden there is a Roman military camp.
Now if there was even a shred of proof that there was a military camp, I'd allow that possibility.
BUT SINCE ONLY A MINORITY OF BATH-HOUSES WERE PART OF ROMAN MILITARY CAMPS, we can't even begin to entertain the idea that this part of a camp.
The logic would have to be:
1) There were Romans in Palestine in the first century
2) there's a Roman bath in Nazareth
3) Roman baths were in Roman military camps
4) Therefore there must have been a Roman military camp at Nazareth
So I'll refute:
1) Yes. Obviously there were Romans in Palestine
2) Yes. There's a Roman bath in Nazareth, whose nature and date have not been verified by ANYONE. Yes, the Roman period is from about 100BCE-400CE. So yes, it could be first century, but it almost certainly isn't.
3) Yes. Roman baths were part of Roman military camps. But most baths were attached to other buildings and houses in an urban setting.
4) Yes, there were Roman military camps with bath-houses. But in Nazareth, the Roman bath-house is only evidence that a Roman-era bathhouse was in Nazareth. Maybe.
