Marathi people have a long literary tradition which started in the ancient era. It was the 13th-century saint, Dnyaneshwar who produced the first treatise in Marathi on the Geeta. The work called Dnyaneshwari is considered a masterpiece. Along with Dnyaneshwar, his contemporary, Namdev was also responsible for propagating Marathi religious Bhakti literature. Namdev is also important to the Sikh tradition, since several of his compositions were included in the Sikh Holy book, the "Guru Granth Sahib". Eknath, Sant Tukaram, "Mukteshwar" and Samarth Ramdas were equally important figures in the 17th century. In the 18th century, writers like Vaman Pandit, Raghunath Pandit, Shridhar Pandit, Mahipati, and Moropant produced some well-known works. All of the above-mentioned writers produced religious literature.
