Mandeans

Al-Jazeera has a very brief portrait of the Mandean community in Baghdad. I confess I've never heard of this religion before, but it appears to be sort of a Gnostic combination of Zoroastrianism, Christianity, and Islam. They trace themselves back to John the Baptist, or the Yahya b. Zakaria of the Qur'an. I also found their official web site here. This site also has a brief but very interesting FAQ.
