quadrivium

These subjects were the Trivium, and the more advanced Quadrivium.

After completing the trivium, those who wished for higher culture studied the quadrivium.

Among the old Romans, a trivium meant a place where three ways met, and a quadrivium where four, or what we now call a cross-road.

Likewise arithmetic and the rest of the quadrivium have place in the clerics education.

Passing to the Quadrivium, we find that Fulbert had studied its four branches under Gerbert.
