Triumph of Labour- This is an open-air large-scale sculpture in bronze made by Debi Prasad Roy Chowdhury (1899–1975). It was installed at Marina Beach, Chennai, on the eve of the Republic Day in 1959. It shows four men trying to move a rock, rendering the importance and contribution of human labour in nation building. Unconquerable men are wrestling with nature, doggedly, indeterminately and powerfully. It is an image of labour against the elements of nature, a well-known romantic subject of the nineteenth century. Chowdhury loved to dwell on the strong musculature of his workers, revealing their bones, veins, flesh, etc. He portrayed the extreme physical effort of loosening a massive, immovable rock. Human figures are installed in a way that create a curiosity in us as viewers. It attracts the viewers to see it from all sides. The image of group labour is placed on a high pedestal, thereby, replacing the notion of portraits of kings or British dignitaries.
