“Holy shadows of the dead, I am not to blame for your cruel and bitter fate, but the accursed rivalry which brought sister nations and brother people to fight one another. I do not feel happy for this victory of mine. On the contrary, I would be glad, brothers, if I had all of you standing here next to me, since we are united by the same language, the same blood and the same visions."

Curtius Rufus, Historia (Battle of Chaeronia 338 B.C.) - Alexander the Great wept after the battle of Chaeronea where Greek met Greek on the battlefield for hegemony over Greece.
