How Seneca became Ancient Rome’s philosopher-fixer.

Sometime in the spring of the year 59, the emperor Nero decided to murder his mother. As you can imagine, the two were not on good terms. In a gesture designed to appear conciliatory, Nero invited his mother, Agrippina, to join him at a festival in Baiae, a resort town near present-day Naples. During the festivities, he treated her with great affection. Then, when it was time for her to leave, he presented her with a gift—a beautifully appointed boat to ferry her up the coast. The gift was supposed to be a death trap. But just about everything that should have gone wrong didn’t. The deck of the ship fell in, yet, rather than killing Agrippina, it crushed one of her attendants. The hull, too, had been crafted to break apart; in all the confusion, though, it failed to do so. The rowers tried to overturn the ship. Once again, the effort fell short. Agrippina and a second attendant, Acerronia, swam free. Acerronia—“rather unwisely,” as Tacitus puts it—kept screaming that she was Agrippina and needed help. The rowers rushed over and bashed her on the head with their oars. The real Agrippina slipped away. She was picked up by a fishing boat and deposited safely onshore. When Nero learned that his mother had survived, he sent his minions to stab her.
This series of unfortunate events put the emperor in a pickle. The whole point of the affectionate display and the gift of the boat had been to make Agrippina’s death look like an accident. (Even in imperial Rome, matricide was, apparently, bad P.R.) Now this was impossible. And so Nero turned to the man he had always relied on, Lucius Annaeus Seneca, better known as Seneca the Younger, or just plain Seneca.
If poets and philosophers dream of influencing those in power, Seneca was uniquely positioned to do so. He was a celebrated rhetorician, a satirist, the author of several books of natural history, and a playwright. He was also what today might be called an ethicist. Among his many works of moral philosophy are “De Ira” (“On Anger”), “De Providentia” (“On Providence”), and “De Brevitate Vitae” (“On the Shortness of Life”). Seneca had been Nero’s tutor since the younger man was twelve or thirteen, and he remained one of his closest advisers.
