I'm working with some old atlases, and one of them (Tunison's Peerless Universal Atlas of the World, published in 1896) has a comparison chart of the populations of different religions. The biggest, at 500,000,000 million, is 'Pagans etc.' What would that mean to a contemporary reader?
(The other religions, for reference: Buddhists, Mohammedans, Roman Catholics, Protestants, Greek Christian, and Jews.)
Since it includes the term etc. and is listed alongside these other religions, is there a reason not to take the trivial "everything else" answer at face value? Practitioners of other religions, with Hindus being a particularly notable exception to the list given?
