This document provides context and summaries for John Milton's epic poem Paradise Lost. It describes how Satan, originally one of God's highest angels, rebelled against God and was cast into Hell along with one third of the angels. In Hell, Satan rallies the fallen angels and convinces them to explore the newly created Earth in an attempt to undermine God. The document then provides summaries for each of the first two books of Paradise Lost, covering Satan's speech to the other fallen angels in Hell, their building of the palace Pandemonium, and Satan's journey to Earth where he enters the Garden of Eden and is discovered spying on Adam and Eve by angels.
