One of the greatest works of world literature, Dante Alighieri's The Divine Comedy has, despite its enormous popularity and importance, often stymied readers with its multitudinous characters, references, and themes. But until now, students of the Inferno have lacked a suitable resource to guide their reading. This book takes readers on a geographic journey through Dante's underworld circle by circle—from the Dark Wood down to the ninth circle of Hell—in much the same way Dante and Virgil proceed in their infernal descent. Each chapter—or “region”—of the book begins with a summary of the action, followed by detailed chapters, significant verses, and useful study questions. The chapters, based on a close examination of the poet's biblical, classical, and medieval sources, help locate the characters and creatures Dante encounters and assist in decoding the poem's vast array of references to religion, philosophy, history, politics, and other works of literature.
