About one thousand years ago, a phenomenon occurred in a fertile tract of Mississippi River flood plain known today as the "American Bottom." This phenomenon came to be called Cahokia MoundsAmerica's first city. Interpreting the rich heritage of a site like Cahokia Mounds is a balancing act; the interpreter must speak as a scholar to the general public on behalf of an entirely different civilization. Since even those three groups are splintered into myriad dialects of perspective, sometimes it is hard to know what language to use. But William Iseminger's work at the site has given him nearly four decades of practice in Cahokia Conversation 101, and he tells the story of the place and its ancient culture (as well as its place in contemporary culture) with the clarity and confidence of a native speaker.
