A solo performer in a squash-like costume inhabits the Duveen Galleries every day for more than six months for the Tate Britain Commission 2018. Each element of The Squash has evolved from Hamilton’s interest in a photograph she found in a book several years ago when looking at improvisational theatre and participatory art practices in the 1960s and 1970s. It showed a person dressed as what looks like a vegetable lying among vines. The original photograph dated from 1960 and depicted a scene from a dance by American choreographer Erick Hawkins. Hawkins was interested in Native American philosophies and he took the form of this costume from the Squash Kachina of the Hopi culture.
