Now called Gioura, or Jura. It was little better than a barren rock, though inhabited; but so notorious for its poverty, that its mice were said to be able to gnaw through iron. It was used as a place of banishment under the Roman emperors, whence the line of Juvenal, i. 73—
“Aude aliquid brevibus Gyaris et carcere dignum.”
“Dare some deed deserving of the little Gyara and the gaol.” It is now uninhabited, except by a few shepherds in the summer.
