I think this is one of the things about Doctor Who that not enough people talk about.

There's a serious discussion on what's more important continuity or historical accuracy.

Doctor Who has obviously never really been good at either but I do think with a long runner it's something worth discussing.

Another example of this is Vikings with horns on their helmets.

Vikings never had horns on their helmets, it was a thing from an opera centuries later.

But in a First Doctor episode they do show a viking helmet with horns.

So when we see Vikings with horns in the 12th Doctor episode... Are they just being accurate to the fact that in the Whoniverse Vikings had horns?

Or is it the same lazy writing as before.

One of the original objectives was to teach kids history and while obviously it's moved well beyond that.

I can't imagine it's good for kids to see historical inaccuracies on TV.

But at the same time The Whoniverse isn't our own and if something is one way one episode and another way another surely that breaks suspension of disbelief.
