Synopsis In recent decades, marine archaeologists working in near-shore underwater areas have brought to light new find of enormous value. Scholars, working in their respective discipline areas concerning specific ports, have not been able to build a holistic perspective on the ports of the past, and their rise and decline. This is, to an extent, due to a lack of sea-perspective of the ports and their navigational environment.

To fill this gap, through an interdisciplinary and integrative approach, the present work on navigational environment of the old and mediaeval ports of Tamilaham has been attempted. The book incorporates all available knowledge gathered till date.
