- I put that assertion there and I think I got that information from Heinrich Dörrie's book of problems of elementary mathematics, which is clearly not a primary source. I suspect it can be found among Thomas Heath's translations of works of ancient Greek mathematicians. Michael Hardy 21:10, 11 Feb 2004 (UTC)
