This fourth volume of the Philo of Alexandria Commentary Series, originally published by Brill in hardcover, presents the first readable, modern English translation and commentary on Philo's De agricultura (On Cultivation), which gives an elaborate allegorical interpretation of Genesis 9:20. Albert C. Geljon and David T. Runia focus on the treatise's structure, biblical sources, and exegetical and philosophical contents. The volume provides valuable insights into Philo's highly influential allegorical method of biblical interpretation.
