The water warms to as much as ninety-six degrees Celsius. Under pressure, it rises along fissures and faults until, at the very point where the Pennyquick fault breaks surface in the middle of Bath, it bubbles up at forty-six degrees and 1.17 million litres a day. That spring has been doing this for thousands of years. The Celts worshipped it. The Romans built their temple over it in the 60s AD. Anglo-Saxons saw the ruined baths and called the place a wonder. The water you can see today - greenish, faintly steaming on a cold morning - fell as rain ten thousand years ago.

It has snakes entwined in its beard, wings above its ears, beetling brows and a heavy moustache - and most scholars now read it as a syncretism, Minerva's tradit...

Roman Baths (Bath): What the Water Knows
