An unrivaled compendium of ancient Roman knowledge.

Pliny the Elder, Gaius Plinius Secundus (AD 23–79), a Roman of equestrian rank of Transpadane Gaul (N. Italy), was uncle of Pliny the letter writer. He pursued a career partly military in Germany, partly administrative in Gaul and Spain under the emperor Vespasian, and became prefect of the fleet at Misenum. He died in the eruption of Vesuvius when he went to get a closer view and to rescue friends. Tireless worker, reader, and writer, he was author of works now lost; but his great Natural History in thirty-seven books with its vast collection of facts (and alleged facts) survives—a mine of information despite its uncritical character.

The contents of the books are as follows. Book 1: table of contents of the others and of authorities; 2: mathematical and metrological survey of the universe; 3–6: geography and ethnography of the known world; 7: anthropology and the physiology of man; 8–11: zoology; 12–19: botany, agriculture, and horticulture; 20–27: plant products as used in medicine; 28–32: medical zoology; 33–37: minerals (and medicine), the fine arts, and gemstones.

The Loeb Classical Library edition of Natural History is in ten volumes.

Following nature in pursuit of ethics.

Seneca, Lucius Annaeus, born at Corduba (Cordova) ca. 4 BC, of a prominent and wealthy family, spent an ailing childhood and youth at Rome in an aunt’s care. He became famous in rhetoric, philosophy, money-making, and imperial service. After some disgrace during Claudius’ reign he became tutor and then, in AD 54, advising minister to Nero, some of whose worst misdeeds he did not prevent. Involved (innocently?) in a conspiracy, he killed himself by order in 65. Wealthy, he preached indifference to wealth; evader of pain and death, he preached scorn of both; and there were other contrasts between practice and principle.

We have Seneca’s philosophical or moral essays (ten of them traditionally called Dialogues)—on providence, steadfastness, the happy life, anger, leisure, tranquility, the brevity of life, gift-giving, forgiveness—and treatises on natural phenomena. Also extant are 124 epistles, in which he writes in a relaxed style about moral and ethical questions, relating them to personal experiences; a skit on the official deification of Claudius, Apocolocyntosis (in LCL 15); and nine rhetorical tragedies on ancient Greek themes. Many epistles and all his speeches are lost.

The treatises on natural phenomena, Naturales Quaestiones, are collected in Volumes VII and X of the Loeb Classical Library’s ten-volume edition of Seneca.
