The Taishang dongyuan shenzhou jing (simplified Chinese: 太上洞渊神咒经; traditional Chinese: 太上洞淵神咒經; pinyin: Tàishàng dòngyuān shénzhòu jīng; Wade–Giles: T'ai-shang shen-chou ching; literally: "Most High Cavernous Abyss Divine Spells Scripture"), or The Divine Incantations Scripture, is the oldest known Chinese classic text that details an apocalypse. The earliest portions of the book have been traced back to the beginning of the fifth century CE, with subsequent commentary attesting an origin in the early fourth; the book likely integrates older traditions.
