Vanshri- This artwork was created by Mrinalini Mukherjee in 1994. She uses an unusual material to make this sculpture. She uses hemp-fibre, a medium that she experimented with from the early 1970s. Going by the intricate way, she has knotted together and woven a complex shape out of jute fibre. It seems to be the result of years of handling the new material. For many years, her works of this kind were dismissed as craft. Only recently her fibre works have attracted a lot of attention for originality and boldness of imagination. In this work, entitled Vanshri or ‘Goddess of the Woods’, she turns this ordinary material into a monumental form. If one carefully looks at the figure’s body, one can notice that it has a face with an inward expression and protruding lips, and above all, a powerful presence of natural divinity.
