The Noontide of Valinor or the Days of Bliss was the period that followed the making of the Two Trees of Valinor, when Aman was bathed by their extraordinary silver-gold light. In this time the Calaquendi or the Elves of the Light lived in peace alongside the Valar, and Melkor was imprisoned within the Halls of Mandos. The Noontide (the term is meant symbolically, representing the time of greatest glory) lasted for three ages, but with Melkor's release the the bliss of Aman began to to fail. Eventually, Melkor's corruption led to the Darkening of Valinor, in which the Two Trees were destroyed forever.
