Sporus of Nicaea


Sporus of Nicaea was a Greek mathematician and astronomer, probably from Nicaea, ancient district Bithynia in province Bursa, in modern-day Turkey.
Much of his work focused on squaring the circle and reproducing cubes, both in his own attempts at these problems or in criticizing the work of other contemporary mathematicians.
Sporus also criticized Archimedes for not producing a more accurate approximation of π.
