From Jonathan Swift's 'Travels into Several Remote Nations of the World. In Four Parts. By Lemuel Gulliver.'Reuse content
"One Day in much good Company I was asked by a Person of Quality, whether I had seen any of their Struldbruggs or Immortals. I said I had not, and desired he would explain to me what he meant by such an Appelation applied to a mortal Creature. He told me that sometimes, though very rarely, a Child happened to be born in a Family with a red circular Spot on the Forehead, directly over the left Eyebrow, which was an infallible Mark that it should never die.
