Citron is the oldest known variety of citrus. Seeds of citron were found in excavations of the town of Nippur in the southern part of Babylon (present-day Iraq). These ruins date back to 4000 B.C. It is not known whether Mesopotamians cultivated citron at that time or imported the fruit from the east, but the seed-finds prove that citron was known to them at least 6000 years ago.
