I'm also interested in the world's most popular religions before the one before Christianity -- eg, Hinduism was the world's largest religion, until superseded by Buddhism, until superseded by the Roman religion, until superseded by Christianity. What was the progression of religion's heavy hitters? Largest = total number of believers worldwide.
