"[Julius] Caesar served in 63 BC as a quaestor in Spain, where in Cadiz he is said to have broken down and wept in front of a statue of Alexander the Great, realizing that where Alexander had conquered most of the known world at thirty, Caesar at that age was merely seen as a dandy who had squandered his wife's fortunes as well as his own."
