In 2270, Spock informed Captain James T. Kirk that the library computer confirmed that Ensign Walking Bear was correct about studying the histories of many ancient Earth peoples, especially his own. The computer shows information that said "The Mayas had a legend of a winged serpent god who came from the skies, bringing knowledge." (TAS: "How Sharper Than a Serpent's Tooth")
