Faust is a dramatic poem in verse. It opens with a Prologue in Heaven where the Lord and Mephistopheles wager over a single human soul. The Lord grants the devil permission to tempt his servant Faust, confident that a good man, even while erring, keeps an instinct for the right path. This frame turns the whole play into a test of whether restless human striving leads to ruin or to grace.
We meet Faust at midnight in a cramped Gothic study, surrounded by books and instruments. He has studied every discipline and gained titles, yet confesses that nothing can truly be known, and that this is what cuts him to the bone. He turns to magic to grasp the inmost force that holds the world together, conjures spirits, recoils from them, and in despair nearly drinks poison before Easter bells call him back to life.
Mephistopheles appears and offers Faust a pact. He will serve Faust on earth and show him every experience; in return Faust will serve him beyond the grave. Faust frames it as a wager: if ever he is so contented by a passing moment that he begs it to stay because it is so fair, then he is willing to be lost. He signs in a drop of blood, and the two set out into the world.
The central tragedy is Margaret's, a pious and trusting young woman whom Faust desires and, with the devil's help, seduces. To clear the way, the lovers' actions bring about the death of her mother, and Mephistopheles helps Faust kill her brother Valentine in a duel. Abandoned, pregnant, and broken, Margaret drowns her newborn child and is imprisoned for the murder, awaiting execution.
The play closes in her dungeon. Faust, guilt-stricken, comes with Mephistopheles to free her, but her mind has shattered and she will not flee with the man who ruined her; she gives herself instead to the judgment of God. As Mephistopheles declares her condemned, a voice from above answers that she is saved, and Faust is dragged away. Part One ends with the devil's bargain unresolved and its first victim redeemed.
