Leizu (Chinese: 嫘祖; pinyin: Léi Zǔ) was a legendary Chinese empress and wife of the Yellow Emperor. According to tradition, she discovered silk and invented the silk loom in the 27th century BC.
Leizu discovered silkworms while having a midday tea, and a cocoon fell in her tea.
According to one account, the silkworm fell into her tea, and the heat unwrapped the silk until it stretched across her entire garden. When the silk ran out, she saw a small cocoon and realized that this cocoon was the source of the silk. Another version says that she found silkworms eating the mulberry leaves and spinning cocoons. She collected some cocoons, then sat down to have some tea. While she was sipping a cup, she dropped a cocoon into the steaming water. A fine thread started to separate itself from the silkworm cocoon. Leizu found that she could unwind this soft and lovely thread around her finger.
She persuaded her husband to give her a grove of mulberry trees, where she could domesticate the worms that made these cocoons. She is attributed with inventing the silk reel, which joins fine filaments into a thread strong enough for weaving. She is also credited with inventing the first silk loom. It is not known how much, if any, of this story is true, but historians do know that China was the first civilization to use silk. Leizu shared her discoveries with others, and the knowledge became widespread in China.
She is a popular object of worship in modern China, with the title of 'Silkworm Mother' (Cangu Nainai).[1]
