Valmiki ( - 400)

Valmiki (Sanskrit: वाल्मीकि; In Diacritical Marks:Vālmīki; during Lord Śrī Rāma's time) is celebrated as the harbinger-poet in Sanskrit literature. He is the author of the epic Rāmāyaṇa, based on the attribution in the text of the epic itself. He is revered as the Ādi Kavi, which translates to First Poet, for he discovered the first śloka i.e. first verse, which set the base and defined the form to Sanskrit poetry.
