The First Age, the Age before the Age of Legends, ended many thousands of years before the time of the novels. Little is known of this period of history, save that the portal stones come from this epoch. There are stories of this time which gleemen still tell, although they are no doubt heavily corrupted from the original events. Some fans believe this to be the time in which the readers live, based upon several legends mentioned throughout the series as well as certain artifacts in the Panarch's Palace.
The story of Lenn, who flew to the moon in the belly of an eagle made of fire, and his daughter Salya who walked among the stars. Jordan has confirmed these to be references to John Glenn and Sally Ride. Among the first words uttered by Neil Armstrong on the first moon landing were "The eagle has landed."
The portal stones found in random locations across the world are said to be older than the Age of Legends, and even the Aes Sedai of the Second Age were uncertain of their precise origin and operation.
The museum of the Panarch's Palace in Tanchico holds several items said to date from this age, including a freize depicting animals unknown in the Third Age (including what is recognizably a giraffe) and a strange symbol representing hubris, which resembles a three-pronged star (this is reminiscent of the hood ornament from a Mercedes-Benz car).
The glass columns of Rhuidean may have existed before the Age of Legends. Aviendha, who has a Talent of reading ter'angreal, is stupified and unable to succesfully read the glass columns. Aviendha herself doubts that Aes Sedai of the Age of Legends understood how it worked.
