"To the north of Armenia lies Zorzania Georgia, near the confines of which there is a fountain of oil which discharges so great a quantity as to furnish loading for many camels. The use made of it is not for the purpose of food, but as an unguent for the cure of cutaneous distempers in men and cattle, as well as other complaints, and it is also good for burning. In the surrounding country no other oil is used in their lamps, and people come from distant parts to procure it."
