'The Mound Builders" always was one of Lanford Wilson's Big Question plays -- easier to admire, perhaps, than to embrace. The drama, set on an archaeological dig in southern Illinois, ran less than a month in 1975 and was revived briefly in a more melodramatic, less metaphysical, no-more-popular version in 1986.
