The Epistulae morales ad Lucilium (Moral letters to Lucilius) is a bundle of 124 letters which were written by Seneca the Younger at the end of his life. These letters all start with the phrase "Seneca Lucilio suo salutem" (Seneca greets his Lucilius) and end with the word "Vale" (Farewell). In these letters, Seneca gives Lucilius tips on how to become a more devoted Stoic. Lucilius was, at that time, the Governor of Sicily, although he is known only through Seneca's writings. Some of the letters include "On Noise" and "Asthma". Others include letters on "the influence of the masses" and "how to deal with one's slaves". Although they deal with Seneca's eclectic form of Stoic philosophy, they also give us valuable insights in the daily life in ancient Rome.
