What premise in literary criticism is credited to Dante Alighieri?

Dante Alighieri is known for his influential work in poetic form and his exploration of literary themes, particularly in "The Divine Comedy." One prominent aspect of his literary criticism is the idea that literature can be interpreted on both literal and allegorical levels. This duality allows for a rich exploration of meaning, where surface details can lead to deeper philosophical, moral, and spiritual insights. Dante’s work exemplifies this approach, using allegorical elements to convey complex ideas about the human condition, morality, and the afterlife.

By promoting the interpretation of texts on two levels, Dante not only enriches the reader's experience but also encourages a deeper engagement with the text. This premise has significantly influenced literary criticism, allowing future writers and critics to appreciate the layered meanings within literary works.
