Graeber / Wengrow: "By plant-based knowledge we don't just mean new ways of working with wild flora to produce food, spices, medicines, pigments or poisons. We also mean the development of fibre-based crafts and industries, and the more abstract forms of knowledge these tend to generate about properties of time, space, and structure."
Also, "the development of mathematical and geometrical knowledge that is (quite literally) intertwined with the practice of these crafts. Women's association with such knowledge extends back to some of the earliest surviving depictions of the human form" [we have Ice Age figurines depicting women with "woven headgear, string skirts and belts made of cord"]
