Lu Ban
China's patron of carpenters and builders, Lu Ban lived in the State of Lu in the fifth century BCE, a contemporary of the philosopher Mozi. Tradition credits him with the saw, the plane, the ink-line and more; temples across China deified him, and builders still invoke his name.
The Mozi, compiled in the centuries after both men lived, records that Lu Ban carved a magpie of bamboo and wood that flew for three days without landing, and counted it his masterpiece. Mozi retorted that the linchpin he himself could whittle in a moment carried a cart's load of grain, while the bird carried nothing: skill that serves people is craft, skill that does not is cleverness. The exchange is still quoted in Chinese arguments about technology's purpose.
“A craftsman is judged by what the work carries, not by how cleverly it flies.”
