The Geoponica or Geoponika (Greek: Γεωπονικά) is a twenty-book collection of agricultural lore, compiled during the 10th century in Constantinople for the Byzantine emperor Constantine VII Porphyrogenitus.
During the Macedonian Renaissance, the emperor Constantine VII assembled several compendia - compilations and excerpts of ancient writings - of which Geoponika was one.
The ultimate sources of the Geoponica include Pliny, various lost Hellenistic and Roman-period Greek agriculture and veterinary authors, the Carthaginian agronomist Mago, and even works passing under the name of the Persian prophet Zoroaster.
Syriac, Pahlavi, Arabic and Armenian translations attest to its worldwide popularity and complicate the manuscript tradition still further.
The Geoponica embraces all manner of "agricultural" information, including celestial and terrestrial omina, viticulture, oleoculture, apiculture, veterinary medicine, the construction of fish ponds and much more.
