Scipio Africanus came from the ancient Roman patrician family of the Cornelii and was the father of Cornelia, the famous mother of the social reforming brothers known as the Gracchi. He came into conflict with the somber Cato the Elder and was accused of corruption. Later, Scipio Africanus is a figure in the fictional "Dream of Scipio". In this surviving section of De re publica, by Cicero, the dead Punic War general tells his adoptive grandson, Publius Cornelius Scipio Aemilianus (185-129 B.C.), about the future of Rome and the constellations. Scipio Africanus' explanation worked its way into medieval cosmology.
