The ancestor spirits of the Pueblo Indians in North America, these
were associated with all parts of daily life and in certain
festivals, were played by dancers wearing feathered masks. The Hopi
Indians also believed in kachinas, considering them to be the souls
of virtuous dead people. They exist in the spirit world for half the
year, then return to the Hopi from winter to midsummer. There are
over three hundred different kachinas, each with its individual
personality and mask.
