Satan gains entrance into the Garden of Eden, where he finds Adam and Eve and becomes jealous of them. He overhears them speak of God's commandment that they should not eat the forbidden fruit. Uriel warns Gabriel and his angels, who are guarding the gate of Paradise, of Satan's presence. Satan is apprehended by them and banished from Eden. God sends Raphael to warn Adam and Eve about Satan. Raphael recounts to them how jealousy against the Son of God led a once favored angel to wage war against God in heaven, and how the Son, Messiah, cast him and his followers into hell. He relates how the world was created so mankind could one day replace the fallen angels in heaven.
