During the reign of King James IV Inchkeith was the site of an extraordinary experiment. According to the historian Robert Lyndsay of Pitscottie, in 1493 James directed that a dumb woman and two infants be transported to the island, to ascertain which language the infants would grow up to speak when isolated from the rest of the world. It was thought that this would be the "original" language, or language of God. There is no reliable account of how the infants spoke although Lyndsay of Pitscottie reported that "some say they spoke good Hebrew".
