A 60,000-year-old flower burial
In Shanidar Cave, south of Hakkari, pollen of medicinal plants, ephedra among them, was found around a Neanderthal man buried about 60,000 years ago. The grave was called the “flower burial”, and it was even claimed to be a shaman’s. But some researchers think a rodent, the Persian jird, carried the pollen into the cave. So it is not certain that the plants were left there in a ritual.
