Photos by Sooni Taraporevala, and an interview on NPR with Jennifer Ludden.
She talks about the religious origins of Zoroastrianism, and tells some stories about the arrival of the Parsis (originally from Iran) in India. Also see Wikipedia on Zoroastrianism. Other famous Parsis include Freddy Mercury of the rock band Queen (who was actually of Indian origin), the conductor Zubin Mehta, and both Homi Bhabhas (the literary theorist and the nuclear scientist, no relation as far as I know).
