The epic Ramayana is a central Hindu Scripture, which, unlike the Vedas and Upanisads, has been accessible to all sections of the Society. The story originated from an oral tradition and was written down by the sage Valmiki. The date is disputed and could be anything between 1500 and 200 BC. It is said to be the "adikavya", the first and the ideal poem.
