A hundred miles south of Cairo a stretch of the Nile was once considered Egypt's main highway, used by Cleopatra to travel the country. More than 2,000 years after her, Bettany visits a vast desert catacomb where tens of thousands of mummified animals were once left as an offering. Further upstream, there is a chance to swim in the Nile, and look inside the tombs where Tutankhamen's discoverer, Howard Carter, first got hooked on Egypt. Bettany explores the longest tomb yet found, before heading to the Dendera temple, where Cleopatra herself may have once wowed her lover Julius Caesar.

The clean minimalism of the Japanese home has been exported around the world, from modernist architecture to lifestyle stores like Muji. But the origins of this ubiquitous aesthetic evolved from a system of spiritual and philosophical values dating back centuries. James visits one of Japan's last surviving traditional wooden villages, and the 17th-century villa of Rinshunkaku, and reveals how the unique spirit of Japanese craftsmen turned joinery into an artform - creating houses without the need for nails, screws or glue. Exploring some of the traditional arts of the Japanese home, James also investigates attitudes to domestic culture in modern Japan, meeting photographer Kyoichi Tsuzuki, chronicler of Japan's crowded cities and tiny apartments. Other highlights include a performance by calligrapher and artist Tomoko Kawao and a visit to the hometown of architect Terunobu Fujimori.
