I read about the Yezidi in Fortean Times a short time ago and found more information about them on the web. They live in Iraq, are Kurdish in origin and language, but have a culture and religion quite distinct from other Kurds. They literally worship a fallen angel — a reformed fallen angel. Malak Ta’us, a peacock spirit. When he repented, he filled seven jars with his tears, and used them to quench the fires of Hell. He created the world from the broken sharts of a perfect pearl created by the supreme God.
