A potential plot hole. How likely is it that Crowley wouldn't know of the angel exorcism spell in order to use it against Gadreel?

Anther possible plot hole. Crowley references his time with Naomi in mesopotamia. The region corresponding to mesopotamia hasn't been known by that name since the 7th century and Crowley is only about 400 years old.
