Imperial Calendar in the Third Year of Emperor Jia Jing’s Reign in the Ming Dynasty
The Da Ming Jiajing san nian datong li (Imperial calendar, or great universal system of calculating astronomy) is based upon the system of calendrical astronomy developed by the astronomer Guo Shoujin during the Yuan Dynasty (1279-1368). It was officially adapted by the Ming Bureau of Astronomy in 1384. It specified the phases of the moon and contained predictions of when lunar and solar eclipses would occur. The great Chinese navigator Zheng He used Guo Shoujing's methods to determine latitude and longitude on his voyages to the Pacific and Indian ...

This nautical astrolabe is thought to be among the earliest surviving nautical astrolabes and dates from about 1500−1520. Most nautical astrolabes had a carved mater (graduated circular element), unlike the solid and compact instrument shown here, which bears a resemblance to the astrolabes of Diogo Ribeiro (died 1533), a Portuguese cartographer and inventor who spent most of his life in Spain. The purpose of nautical astrolabes was to measure the altitude of the sun or a star above the horizon. Navigators could determine a ship’s latitude by knowing ...

In 14 chapters, the author goes through methods for the computation of these factors, determination of the direction of prayer (qibla), and time of the day. He observes that using instruments (ālāt), such as markings on the ruler (mistara) and the compass (bargār, from the Persian pargār), and geometric ...
