For example, in [[The Silmarillion]] by [[J. R. R. Tolkien]], a Golden Age exists in [[Middle-earth]] legendarium. [[Arda (Middle-earth)|Arda]] (the part of the world where [[The Lord of the Rings]] is set), was designed to be symmetrical and perfect. After the wars of the Gods, Arda lost its perfect shape (known as [[Arda Unmarred]]) and was called [[Arda Marred]]. Another kind of 'Golden Age' follows later, after the Elves awoke; the [[Eldar (Middle-earth)|Eldar]] stay on [[Valinor]], live with the [[Vala (Middle-earth)|Valar]] and advance in arts and knowledge, until the rebellion and the fall of the [[Noldor]], reminiscent of the Fall of Man. Eventually, after the end of the world, the [[Silmaril]]li will be recovered and the light of the [[Two Trees of Valinor]] rekindled. Arda will be remade again as [[Arda Healed]].
