I recently learned that in West the weekdays are named after Roman gods, but in English it's done by the way of Germanic gods. It's just that Romans, when visiting German tribes, interpreted local gods as Roman ones, simply with different names—as they did everywhere else too. So they brought the calendar with them, and explained that Odin is the same as Mercury, etc, and thus where Romance languages have ‘mercredi’ and such, English has wōdnesdæġ. ‘History of the English language’ is a splendid podcast.
