The legacy of Hellenic Greece over the world was rich and vast, but we will focus in this paper on the main subjects that inspired the future development of civilization: politics, mathematics and art.

Their ideas that numbers where the base of everything in the world, from technology to arts and music, and that mathematics are the base of nature itself, contributed to the scientific development of our days.
