Lucius Annaeus Seneca, (1 B.C.- 65 A.D.) when writing his Moral Epistles to Lucilius, adopted a unique style of writing in order to be coherent with the new litterary genre that he proposed: the philosophical letter. Given Seneca's opinion on the matter in the seventy-fifth epistle, this presentation will provide a commented translation of this letter, which will outline some aspects of Seneca's style, taking into account the resources present in his works.
