It odd - but in The Time Machine by H. G. Wells the oceans of the future are portrayed as calm - flat - with few waves - an image that’s appeared in other science fiction stories about a far distant future. Seems the collective subconscious understands moon power’s effect on waves wanes over time.
There’s an old Welsh tale (in the Mabinogeon) that recalls that the seas were once quiet and flat. Naturally there’s a very odd “explanation” for how the tides began.
Also (dunno the exact source, it’s probably in Bulfinch or Geoffrey of Monmouth or both) there were guardians of wells and springs in pre-Roman Britain (and actually all through Roman times and into the Middle Ages it held on here and there) who did mumbo-jumbo to keep the wells from overflowing and flooding the world. Similar or analogous traditions existed elsewhere in Europe and beyond. The modern survival of this is tossing coins in the fountains and pools (I kid you not).
The ancient Attic Greeks (they had to stay up there, especially when there was company) held that they’d lived in that area since before there was a Moon.
