Nisyrus lies to the north of Telos, at the distance of about 60 stadia, which is its distance also from Cos. It is round, lofty, and rocky, and has abundance of mill-stone, whence the neighbouring people are well supplied with stones for grinding. It contains a city of the same name, a harbour, hot springs, and a temple of Neptune. Its circumference is 80 stadia. Near it are small islands, called the islands of the Nisyrians. Nisyrus is said to be a fragment broken off from Cos; a story is also told of Neptune, that when pursuing Polybotes, one of the giants, he broke off with his trident a piece of the island Cos, and hurled it at him, and that the missile became the island Nisyrus, with the giant lying beneath it. But some say that the giant lies beneath Cos.
