in Ancient Geography, a district of Asia, of which the limits appear to have been very different at different times. In its most limited sense it corresponded very nearly to the modern province of Mazanderan. In its more extended application it comprised, besides that province, those of Khorassan, Dahistan, and Dabistan, and was bounded on the N. by the Caspian or Hyrcanian Sea, W. by the Charindas, which separated it from Media, S. by the Labuta range, which separated it from Parthia, and W. by the Charindas, which separated it from Media. The campaign country of Hyrcania was marshy, but in many places produced considerable quantities of corn and wine. Its mountain districts were densely wooded, and famous for their countless swarms of bees. The capital of the country was indifferently called Carta or Zadra-carta. Very little was known by the ancients about Hyrcania or its inhabitants. When its name occurs it is generally used as a synonym for anything more than ordinarily wild and inhospitable.
