THE NATIONAL GEOGRAPHIC MAGAZINE PERHAPS MARCO POLO HALTED FOR SUCH A CAMEL CARAVAN The famous bridge near Peiping was described by the Venetian explorer. It was built in the twelfth century, and was partially destroyed and restored several times. To the world at large it is the Marco Polo Bridge, though correctly it is the Lu Kou Chiao. Photographs by W. Robert Moore FOR 750 YEARS CHINESE ASTRONOMERS HAVE STUDIED THE STARS This observatory on the east walls of Peiping was founded by Kublai Khan, and in 1685 was modernized by Father Verbiest, a Jesuit priest chosen as Court Astronomer. He designed the bronze star globe, the skeleton celestial globe (right), and the partially concealed instrument (left) to get altitudes and angles, in relation to a meridian, of heavenly bodies.
