汤若望进呈顺治皇帝的新法地平日晷

ADAM SCHALL VON BELL AND HIS SUNDIAL PRESERVED IN THE PALACE MUSEUM

德国传教士汤若望，是继利玛窦之后在华最负盛名的耶稣会士之一，曾在钦天监任职多年。他“依西洋新法”测验天象，制订新历法，观测日食、月食。他曾自制不少天文仪器，日晷就是其中的一种。该文讨论的“新法地平日晷”是他进呈清顺治皇帝的自制品，现存于故宫博物院。这个日晷是中西文化结合的产物。

As one of the famous Jesuits after Matteo Ricci in China, Johann Adam Schall von Bell worked in the Imperial Board of Astronomy for many years. He did astronomical observations, made a new calendar, and observed solar and lunar eclipses according to the Neiw western Calen-dar. He was capable of making things by himself and produced a number of astronmical instruments, one of which was a sundial. This paper focuses on the bori-zontal sundial he made according to the New western calendar and presented to Emperor Shunzhi in 1644. The sundial, a combination of Chinese and western cultures, is now kept intact in the palace Museum.
