The Quest for Immortality. With the rise of archaeology in the eighteenth and nineteenth centuries, scientists began excavating Egyptian tombs and discovering a wide array of gorgeous artifacts. This tomb art is what makes the blockbuster currently on display at the Denver Museum of Nature & Science absolutely fabulous. A traveling exhibit about midway through its coast-to-coast tour, The Quest for Immortality was organized by the National Gallery of Art in Washington, D.C., in collaboration with Copenhagen's United Exhibits Group and Cairo's Supreme Council of Antiquities. An army of scientists, curators and scholars worked on it, headed up by Betsy M. Bryan, a professor at Johns Hopkins University in Baltimore. The heart of the exhibit includes objects found in the tomb of Thutmose III, as well as an astounding digital re-creation of the tomb itself. The show is jammed with visitors, but don't let all the people -- or the steep ticket prices -- dissuade you: This is one show that you've really got to see to believe. Through January 23 at the Denver Museum of Nature & Science, 2001 Colorado Boulevard, 303-322-7009. Reviewed October 7.
