In the Cthulhu mythos created by H.P. Lovecraft, the idea of going mad from revelations about cosmic horrors is a recurring theme. The concept is rooted in the idea that the human mind is not equipped to comprehend the true nature of the universe, especially when confronted with entities or knowledge that challenges fundamental assumptions about reality. The sheer incomprehensibility and existential dread that come with encountering these cosmic horrors can overwhelm the human psyche, leading to madness or a shattered sense of reality. Lovecraft often explored the theme of cosmic insignificance and the fragility of human sanity in the face of the unknown and the unknowable.
