Abstract
Ancient Tamil society developed diverse forms of scientific knowledge and technological practices in response to its environmental, occupational, economic, and social needs. Literary sources, archaeological excavations, inscriptions, and material remains provide valuable evidence of this intellectual and technological heritage. This research paper examines the scientific knowledge and technological practices of the ancient Tamils, with particular attention to pottery technology, black-and-red ware production, high-temperature manufacturing techniques, weaving, and the smelting and shaping of iron. The Inthinai classification of landscapes – Kurinji, Mullai, Marutham, Neithal, and Palai also reflects their understanding of the natural environment, climate, land, water, flora, and fauna. These aspects reveal that their knowledge was closely connected to their interaction with nature and their everyday practices. The study argues that ancient Tamil science and understood not merely as a collection of technical Skills but as an intergrated intellectual tradition combining environmental knowledge, experiential learning> ways of life, and practical technological expertise.
