Tsi-zun-hau-kau's Amazing Stick
Tsi-zun-hau-kau was a nineteenth-century Winnebago chief. A portrait of him painted in the last century shows him posing proudly with a stick in his hand. That stick is now at Michigan's Cranbrook Institute of Science where its carved markings have been under study.
The carvings on the four-and-a-half-foot stick are now known to be a record of the waxing and waning of the moon over a two-year period. Scientists have learned that Winnebago astronomers knew that the number of days in a lunar year turned out to be eleven days shorter than a solar year - and they knew this even before they ever saw the white man's calendar. To correct their lunar calendar so that it would match the solar calendar, the Winnebagos added an extra month every three years. As sophisticated as this calendar is, its structure shows that it is related to prehistoric calendars of the Mayas, Incas, and some of the ancient Siberian cultures.
Man's need to measure time, which predates other written records, shows that man is very different from the animals. The accurate and sophisticated calendars of the ancients deliver a fatal blow to those who picture ancient man as a simple, unintelligent brute who was halfway between animal and modern man. And this higher view of man fits perfectly with what the Bible tells us about man.
