Ignateva Cave

Ignateva cave, also known as Ignatievka cave, Ignatievskaya cave (Russian: Игнатьевская пещера), or Yamazy-Tash, is a large limestone cave on the banks of the Sim River, a tributary of the Belaya river in the southern Ural mountains of Russia.^[2] It was in 1980 the site of the discovery of a wall painting of a venus figure, with twenty-eight red dots between her legs that are believed to represent the female menstrual cycle.^[3][4] The cave also contains microliths, remains of animals, and many other cave paintings, as well as a layer of Iron Age materials.^[5] Although some sources date the paintings in the cave to the Upper Paleolithic,^[5] radiocarbon dating of the pigments in the paintings places their origin more recently, between 6000 and 8000 years ago.^[6]
