When the theme for this year's InkJam ('In The Blink of An Eye') was announced, I wanted to know more about the history of the phrase. The earliest instance I could find was from the Apostle Paul’s first letter to the Corinthians, which describes the moment of apocalypse: "In a moment, in the twinkling* of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed."
(*The English word 'blink' likely comes from blinken, which means to twinkle)
