Lucius Cornelius Sulla Felix (138-78 BC) was considered, and still is, a monstrous Roman emperor, supported by an army of well paid once established terror as a political weapon. He marched on Rome twice, sacked Athens, five thousand men under his command suffered the death penalty, Italic dispossessed peasants to their land to pay the legionaries graduates. But when he realized that his role was fulfilled, he learned to retreat to the pleasant life of the countryside surrounded by young artists and friends reunited. This biography aims, above all, relocate to Silla in the game of political forces of his time and, casting a look back at historical events of that century, facilitating the understanding of the conditions in which the cruel emperor was possible.
