Seneca, the favourite classic of the early fathers of the church and of the Middle Ages, whom Jerome, Tertullian, and Augustine speak of as “Seneca noster,” who was believed to have corresponded with St. Paul, and upon whom1 Calvin wrote a commentary, seems almost forgotten in modern times. Perhaps some of his popularity may have been due to his being supposed to be the author of those tragedies which the world has long ceased to read, but which delighted a period that preferred Euripides to Aeschylus: while casuists must have found congenial matter in an author whose fantastic cases of conscience are often worthy of Sanchez or Escobar.
