Years ago I remember reading a similar article but only remember one point. There was something about floating rocks in the Odyssey actually being ice. I read the Odyssey 65 years ago so I don’t remember details like that. It was one of my favorites.
If the passage is taken as referring to a solar eclipse, Scandinavia had them in 1169 BC, then not another for another century. They had had them in 1185 BC, 1230 and 1239 BC.
I’m not sure if any of them fit the other clues.
You're probably thinking of the "planctae" ("drifting" or "clashing" rocks) - Odysseus encounters them after passing Scylla and Charybdis.
Circe warns Odysseus, explaining that they're the same ones which Jason and the Argonauts encountered during their (earlier) adventures.
The Symplegades .
