or Gililan, a considerable province of Asia in Persia, lying on the side of the Caspian sea, and to the S.W. of it. It is supposed to be the Hyrcania of the ancients. It is very agreeably situated, having the sea on one side and high mountains on the other; and there is no entering in but through narrow passes, which may easily be defended. The sides of the mountains are covered with many sorts of fruit-trees, and in the highest parts of them there are deer, bears, wolves, leopards, and tygers; which last the Persians have a method of taming, and hunt with them as we do with dogs. Gilan is one of the most fruitful provinces of all Persia; and produces abundance of silk, oil, wine, rice, and tobacco, besides excellent fruits. The inhabitants are brave, and of a better complexion than the other Indians, and the women are accounted extremely handsome. Refit is the capital town.

GILHON, (anc. geog.) one of the rivers of Paradise; according to Wellis, the eastern branch of the Euphrates, into which it divides after its conjunction with the Tigris.
