a few years later, described Kumari Kandam as a seat of learning and culture. Sivagnana Yogi (1840-1924) stated that this ancient society was free of any caste system. Kandiah Pillai, in a 1945 work for children, wrote that Kumarikandam was ruled by a strong and just emperor called Sengon, who organized the sangams. In 1981, the Government of Tamil Nadu funded a documentary film on Kumari Kandam. The film, personally backed by the Chief Minister M. G. Ramachandran and directed by P. Neelakantan, was screened at the Fifth International Conference of Tamil Studies in Madurai. It combined the continental drift theory with the submerged continent theory to present Lemuria as a scientifically valid concept. It depicted Kumari Kandam cities resplendent with mansions, gardens, arts, crafts, music and dance. Alleged lost works The Tamil revivalists insisted that the first two Tamil sangams (literary academies) were not mythical, and happened in the Kumari Kandam era. While most Tamil revivalists did not enumerate or list the lost Sangam works, some came up with their names, and even listed their contents. In 1903, Suryanarayana Sastri named some of these works as Mutunarai, Mutukuruku, Mapuranam and Putupuranam. In 1917, Abraham Pandithar listed three of these works as the world's first treatises of music: Naratiyam, Perunarai and Perunkuruku. He also listed several rare musical instruments such as the thousand-stringed lute, which had been lost to the sea. Devaneya Pavanar printed an entire list of the submerged books. Others listed books on a wide range of topics, including medicine, martial arts, logic, painting, sculpture, yoga, philosophy, music, mathematics, alchemy, magic, architecture, poetry, and wealth. Since these works had been lost to the sea, the Kumari Kandam proponents insisted that no empirical proof could be provided for their claims. In 1902, Chidambaranar published a book called Cenkonraraiccelavu, claiming that he had 'discovered' the manuscript from "some old cudgan leaves". The book was presented as a lost-and-found work of the first Sangam at Tenmadurai. The author of the poem was styled as Mutaluli Centan Taniyur ("Chentan who lived in Taniyur before the first deluge"). The work talked about the exploits of an antediluvian Tamil king Sengon, who ruled the now-submerged kingdom of Peruvalanatu, the region between the rivers Kumari and Pahruli. According to Chidambaranar, Sengon was a native of Olinadu, which was located south of the Equator; the king maintained several battleships and conquered lands as far as Tibet.
