The following work is a collection of essays by Cicero, regarding friendship and old age. The Treatise on Friendship is written as a dialogue between prominent figures of the Middle Roman Republic and is set after the death of the younger Scipio Africanus (otherwise known as Scipio Aemilianus, Scipio Africanus Minor or Scipio the Younger). The interlocutors of the dialogue chosen by Cicero are Gaius Laelius, a close friend of the late statesman, and Laelius's two sons-in-law, Gaius Fannius, and Quintus Mucius Scaevola. As for The Treatise of Old Age, it was written by Cicero in his sixty-third year, and is addressed to his friend Atticus. Cicero represents the discourse as delivered by the elder Cato (in his eighty-fourth year) on occasion of young Scipio and Laelius expressing their admiration at the wonderful ease with which he still bore the load of life. Cicero acknowledges that the sentiments put into the mouth of Cato are really Cicero's own. His purpose is to show that old age is not only tolerable, but comfortable by internal resources of happiness.
