    Euclid's Book of Elements
    Euclid, "gave two proofs of the Pythagorean
    Theorem: The first, Proposition 47 of Book I,
    relies entirely on the area relations and is quite
    sophisticated; the second, Proposition 31 of Book
    VI, is based on the concept of proportion and is
    much simpler" (Ratner, 2009).
