Sculptures are basically made by carving stones, wood or by clay modeling. Kerala has many famous sculptors. M. V. Devan, K. S. Radhakrishnan, M. R. D. Dathan, Kanai Kunjiraman and Balan Nambiar are some among them.. Stone tools which are used for carving sculptures were recovered in many parts of Kerala. These along with the cave pictures and sculptures are the visible proof of the ancient civilization and culture that existed here. The pictures carved and drawn on rocks using stone tools can be considered as the primitive models of sculptures.
