Antiquity’s most prolific and influential medical writer and practitioner.

Galen of Pergamum (129–?199/216), physician to the court of the emperor Marcus Aurelius, was a philosopher, scientist, and medical historian, a theoretician and practitioner, who wrote forcefully and prolifically on an astonishing range of subjects and whose impact on later eras rivaled that of Aristotle. Galen synthesized the entirety of Greek medicine as a basis for his own doctrines and practice, which comprehensively embraced theory, practical knowledge, experiment, logic, and a deep understanding of human life and society.

Method of Medicine is a systematic and comprehensive account of the principles of treating injury and disease and one of Galen’s greatest and most influential works. Enlivening the detailed case studies are many theoretical and polemical discussions, acute social commentary, and personal reflections. The Loeb Method of Medicine is in three volumes.

A Roman farmer on farming.

Columella (Lucius Iunius Moderatus) of Gades (Cadiz) lived in the reigns of the first emperors to about AD 70. He moved early in life to Italy where he owned farms and lived near Rome. It is probable that he did military service in Syria and Cilicia and that he died at Tarentum.

Columella’s On Agriculture (De re rustica) is the most comprehensive, systematic, and detailed of Roman agricultural works. Book 1 covers choice of farming site; water supply; buildings; staff. 2: Plowing; fertilizing; care of crops. 3–5: Cultivation, grafting, and pruning of fruit trees, vines, and olives. 6: Acquisition, breeding, and rearing of oxen, horses, and mules; veterinary medicine. 7: Sheep, goats, pigs, and dogs. 8: Poultry; fish ponds. 9: Bee-keeping. 10 (in hexameter poetry): Gardening. 11: Duties of the overseer of a farm; calendar for farm work; more on gardening. 12: Duties of the overseer’s wife; manufacture of wines; pickling; preserving. There is also a separate treatise, Trees (De arboribus), on vines and olives and various trees, perhaps part of an otherwise lost work written before On Agriculture.

The Loeb Classical Library edition of Columella is in three volumes.
