Barbara Hepworth, an English sculptor who lived from 1903 to 1975. Hepworth believed in the idea that certain geometric shapes and forms had inherent symbolic and spiritual meaning. Her sculptures emphasized the interplay between positive and negative space. She was particularly interested in the relationship between geometric shapes and the natural world, and she believed that her sculptures could evoke a sense of harmony and balance in the viewer. One of Hepworth's most famous sculptures, "Single Form," is a large bronze sculpture that consists of two circular forms, one placed inside the other. The sculpture is based on the idea of the circle as a symbol of unity and infinity, and Hepworth believed that the sculpture had a spiritual dimension that transcended its physical form. The curves and angles of the sculpture create a sense of movement and energy, while the balance between the forms reflects the idea of equilibrium. Hepworth's use of sacred geometry in her sculptures reflected her belief in the power of art and nature to evoke spiritual and emotional responses in the viewer. Her work is the embodiment of the elegant simplicity of this philosophy.
