From the pattern's description:
"Among the Cheyenne, only the bravest of fighting
men were entitled to wear "Metaxeszehen", the sacred scalp
shirt. Sacred tradition links the origin of these
shirts to Sweet Medicine, the Prophet, to whom Ma-heo-o
Himself (Creator) first gave the Sacred Arrows and the Cheyenne
code of law. Thus, the making of such a shirt,
trimmed with hair from enemy scalps, was both a holy
and solemn occasion. Only a warrior who himself possessed
a scalp shirt could make one for another warrior.
The holiest of these shirts, were made by a great holy
men such as Box Elder, Crazy Mule or White Bull, all of
them noted warriors as well as holymen.
Among the Lakotas & Oglalas, the Shirt Wearers (as
they were called), were the men who best exemplified the
four great Lakota virtues of compassion, generosity,
bravery, and wisdom, and they must have undergone the four
sacred Lakota ceremonies. They were the leaders and grand
councilors of the tribe, and were required to
advance first in battle and be ready to assist a comrade at
all times. Along with they hard obligations went abundant
protection for the Shirt Wearer, for the blessing of
Ma-heo-o or Wakan Tanka (the Great Mysterious)
rested upon these holy war shirts, as did the blessing of the lesser
Sacred Powers as well. This holiness was reflected in their rich beauty,
being painted with sacred colors and
decorated with quilled or beaded strips with sacred designs.
Thus, the owner of a war shirt had a possession not only of
great beauty, but also filled with great power and
in this way was abundantly blessed."
-Father Peter J. Powell, noted Cheyenne historian.
