The most common form of group scene in Nayarit art is the house group. Believed to evoke the appearance of actual dwellings, most of these houses are on two levels. The upper floor represents the world of the living, where people pursue their everyday lives. The lower level is the underworld, where the activities of departed ancestors closely mirror those of their descendants. The Nayarit believed only a slight barrier separated the two realms, and families, living and dead, remained connected.
