Latin, Greek and Hebrew, particularly, but these Languages being the foundation common to all the Sciences
I don't know why they think Hebrew is related to the sciences. Were Hebrew characters used in scientific formulas? It makes sense that Latin & Greek are used due to the root of many scientific words come from those languages. I'm also slightly surprised that Hebrew was taught due to the lack of a divinity school. The language has a clear connection to Judaism & Christianity. Also, was it "widely spoken" in some part of the world at that time?
