Simon Magus. An interesting overview of an early biblical character famed for working magic. Has lots of translations of early primary-source material, which always catches my eye.
Sacred Books of the East (1900). This casts its net widely, with a good array of sources ranging from Vedic Hymns to a Life of the Buddha. Has several apparently religious sources that I don't know at all, such as selections from the Persian Zend-Avesta. Looks worth digging into.
The Moon-Voyage, by Jules Verne.
