Plains Indian biographic rock art can be "read" by those knowledgeable
in its lexicon. Presented is a lexicon of imagery, conventions, and
symbols used by Plains Indians to communicate their warfare and social
narratives. The reader is introduced to Plains Indian "warrior" art in
all media, biographic art as picture writing is explained, and the
lexicon is described, providing a pictographic "dictionary," and
explains conventions and connotations. Finally, it illustrates four key
examples of how these narratives are read by the observer. Familiarity
with the lexicon will enable interested scholars and laypersons to
understand what are otherwise enigmatic rock art drawings found from
Calgary, Alberta through ten U.S. states, and into the Mexican state of
Coahuila.
