I may have mentioned this one before, but I just came across this website while trying to track down another one of those ‘spa therapy’ type claims which had one being found in the Palace of Nestor (they did find evidence of ‘rose scented oil’ there, but the claim is too vague to go further). Anyhoo, lots of good info on the ongoing dig there:
