Not seven centuries ahead, but who comes to my mind is:

https://en.wikipedia.org/wiki/Athanasius_Kircher (1602–1680)

> One of the first people to observe microbes through a microscope, Kircher was ahead of his time in proposing that the plague was caused by an infectious microorganism and in suggesting effective measures to prevent the spread of the disease.

Roger Bacon, although probably 300 rather than 700.

Bede is another contender.

Thomas Bayes?

...but you might have wait another 400 years to be sure

Albertus Magnus, perhaps.

Though unnamed and I won't provide links, the monks that doodled pictures of things like nuns picking penises off a tree in the margins of books might qualify. It's called marginalia if you're interested.
