For Plum, glass is a metaphor for light and a way to make visible what is invisible. She uses borosilicate glass for its high silica content and its strength. Woven Heaven, Tangled Earth was inspired by her research into ancient Mesoamerican cosmological systems. Plum says: “The woven work in glass that I have done over the last several years was originally inspired by the Mayan goddess Ixchel, the first weaver of the Americas. I later discovered that Mayan and other Mesoamerican traditions use the weaver’s loom as a metaphor for the universe. The loom of the universe is believed to be constructed of filaments of light from which the Heavens and Earth are said to be woven. These woven strands of light can become entangled around the Earth, and it is the job of Mayan shamans to untangle this ‘discord.’ Thus, the act of weaving, for the Maya, symbolically rebuilds and re-energizes the world.”
