I believe the test of the day was your knowledge of euclid's 5th proof in book I of the elements.

In medieval times, this theorem was the end of the road for courses in mathematics or philosophy. It was known as "the bridge of fools" because the figure looks like the truss of a bridge and also because only a fool couldn't make it across.

I was a math major and one of the courses i took required students to perform all of the proofs from books 1 &2 of Euclid's elements
