Proclus (c. 412 – 485) was a Greek Neoplatonist philosopher, one of the last major Classical philosophers. He set forth one of the most elaborate and fully developed systems of Neoplatonism. He stands near the end of the classical development of philosophy, and was very influential on Western medieval philosophy (Greek and Latin) as well as Islamic thought. "Wherever there is number, there is beauty." Proclus, quoted by M. Kline, Mathematical Thought from Ancient to Modern Times.
