 The writings that we shall primarily be concerned with are: the Moral Letters to Lucilius (Ad Lucilium epistulae morales), the Moral Essays (‘dialogi’ or dialogues is the somewhat misleading title given in our principal manuscript, the Codex Ambrosianus, to the twelve books making up ten of these works, including three “consolatory” writings; among the Essays are two further works that came down to us in other manuscripts), and the Natural Questions (Naturales quaestiones) (on the full range of Seneca’s writings, see Volk and Williams 2006, “Introduction,” and Ker 2006; a comprehensive overview, with individual chapters on specific writings and themes, is offered in Heil and Damschen 2014).
