Reply to comment by EasterBunnyArt in Earth's inner core may be slowing down, but “Nothing cataclysmic is happening,” says Hrvoje Tkalcic, a geophysicist at Australian National University. “The inner core is now more in sync with the rest of the planet than a decade ago when it was spinning a bit faster.” by clayt6
Do you have any evidence about the poles switching times during the Roman era? As far as I was aware the last time it happened was like half a million years ago or something, which certainly was not during the Roman era.

Honestly I will have to look into it, but as I said this was over a decade ago and on some Discovery channel or History channel documentary from when they actually still showed scientific material.
So basically this information might be massively outdated or having been disproven by now. Which was why I had mentioned the date of the information / when I learnt about it.
It could have been just a sensationalist documentary and then never retracted.

There is no credible evidence for a total geomagnetic pole reversal during Roman times. The last one was at least 780,000 years ago.
There is however research that talks about localized evolution in the geomagnetic field, for example this one in Iberia

Ah thank you for the links and the second link might be what I was thinking of.
Interesting reads, even if half of it is a bit beyond my normal comprehension.
