Atlantis, though likely a philosophical allegory, has been treated as a real lost world in literature. Plato depicted it as technologically advanced but morally corrupt. In poetry, Atlantis symbolizes utopian ambition, catastrophic downfall, and the fragility of human achievement—often serving as a cautionary myth about pride, or as a nostalgic dream of a perfect society lost beneath the waves.

Atlantis, described by Plato in the dialogues Timaeus and Critias, serves as a cautionary allegory about hubris, imperial overreach, and divine retribution. Though presented as historical, most scholars regard it as philosophical fiction. Nevertheless, Atlantis has captivated poets from Francis Bacon to modern speculative writers as a symbol of lost utopias, submerged knowledge, or civilizational fragility. In poetry, it often functions as a metaphor for ideal societies that vanish due to moral decay—a powerful trope in eco-poetics and post-apocalyptic verse.
