Sawgoek ("root script", IPA: ) or sawva ("insect script", ) was a mythological ancient script mentioned in the Zhuang creation epic "Baeu Rodo" (modern Zhuang script: "Baeuqroekdoz"). The primordial god Baeu Ro was said to have brought "sawgoek" containing four thousand glyphs along with fire to the Zhuang people. However, in their unfamiliarity with fire, the people stored the fire under a thatched roof, causing the house to catch on fire. The "sawgoek" was consumed in the ensuing conflagration, and knowledge of writing was lost. Some Zhuang scholars believe that this myth stems from a vague remembrance of "sawgoek" in the collective consciousness of the Zhuang people long after knowledge of the writing system had been forgotten.
