Tang Ruowang, Zidaowei, is a German. Tang Ruowang got his Chinese name after he came to China. His real name is John? Adam? Sal? Feng? Bail. He was a Jesuit missionary in the Holy Roman Empire, a Catholic Jesuit monk, priest and scholar. At the age of twenty-seven, he set foot on the land of China with 22 missionaries, including Deng Yuhan and giacomo rho, and then lived in China for forty-seven years, experiencing the Ming and Qing dynasties. Since then, these missionaries, who know astronomy above and geography below, have gradually won the praise and trust of China literati by virtue of their own talents. Later, shortly after Tang Ruowang arrived in Beijing, he successfully predicted the eclipses in October 1623 and September 1624 with his rich knowledge of astronomy, mathematics and science, and gained the appreciation and trust from court officials. Later, with the help of Li Zubai, an official of Qin Tianjian, he wrote a Chinese version of "The Theory of Telescope" to facilitate people's understanding of Galileo's telescope. In addition, Tang Ruowang also built a factory for casting cannons in 1636.
Arguably, why did such a person with contribution and knowledge die in the end? The main source is the ancient emperors' attention to geomantic omen. If an emperor, a general, or a royal aristocrat dies, he will send Feng Shui masters to make repeated, careful measurements and precise calculations based on his own understanding of Feng Shui. Although Qin Tianjian is in charge of astronomical calendar knowledge, he is often given the responsibility to take charge of such matters. However, the technique of Kanyu has experienced thousands of years of historical evolution in China. Although Tang Ruowang is proficient in astronomical calendars and knows some of the techniques of Kanyu, he is a foreigner after all. Therefore, it is inevitable that he will be a little rusty if he wants to use the technique of Kanyu flexibly.
After that, Heshuo Rong Qinwang died in the 15th year of Shunzhi. Tang Ruowang and others didn't use it when calculating the date of burial? Positive five elements? , but in accordance with the? Hong Fan Five Elements? Deduct. Although both methods belong to the art of Kanyu deduction, Tang Ruowang was framed for it. Rong Qinwang, who was once deeply favored by your majesty, died a few months after birth. So after the death of Emperor Shunzhi, Yang Guangsheng impeached Tang Ruowang and others in the third year of Kangxi, saying that there was great negligence in deducing the burial date. After that, the case was referred to the meeting of Wang Dachen, who discussed the case. Finally, it was determined that Tang Ruowang and others were indeed negligent, and it was drawn up as a penalty in the year. But in the end, Tang Ruowang was pardoned, and there are two reasons for the pardon at present. The first one is that there was a big earthquake in Beijing when Wang Dachen and others judged Tang Ruowang and others to be guilty of a big crime and sentenced them to a year's imprisonment. Because of the official status of Tang Ruowang, Du Ruyu, Yang Hongliang and others, many people in the imperial court thought that this should be an early warning from heaven and finally decided to forgive them. The second argument is that since Emperor Kangxi was still young at that time, the ministers responsible for the case were the Fuzheng and the Empress Dowager. After weighing the pros and cons, they decided to give Tang Ruowang and others an exemption.
In this way, Tang Ruowang, who lived and worked in China for nearly half a century, finally saved his life. But at that time, he was already seriously ill. After his release, Tang Ruowang spent the last few years of his life and died. And after his death, he was buried on the left side of Matteo Ricci's tomb in Beijing. Kangxi dynasty named him? Dr. Guanglu? , the official is the best.
