Mathematician, born at Milan, 21 December, 1648; died there, 23 February, 1737. In 1663 he entered the Society of Jesus. He was a prolific writer on a variety of subjects, especially mathematics and poetry. He is known today only for the theorem in geometry which bears his name. Ceva's Theorem is: three concurrent lines drawn through the vertices of a triangle divide the opposite sides so that the product of the three distance-ratios is equal to unity. Ceva published this important proposition in 1678. It is the dual of the theorem of Menelaus.
