Alright after several problems, I can connect nicely.

>Everybody, I can't even think of an individual.
(who?) still stands here.

>Maths was still studied in this era although much of what they studied from was Arabic
correct and arabs embraced the knowledge of ancient greek.

>Engineering is a funny old thing, there was not so much history of it in Europe to begin with
roman and greek engineering was successfull.

> Even Geography, much of it is tied to location and trade
yeah it's one of the keys in here because in roman era medditerranean was fully known but after that it's forgotten to some extend again this one is so blatant it's very hard to ignore. thanks to venice mediterranean maps fleshed out again and so on.

> Religion was only tolerated so long as it didn't interfere with the empire
If you're not cult of zealots why wouldnt it? Old religions were already integrated parts of old traditions, pagans did not kill each other in the name of their super righteous cult. This is mostly christian invention.
