Matteo Ricci, Italian priest and mathematician (b. 1552)
Matteo Ricci (Italian pronunciation: [matˈtеːo ˈrittʃi]; Latin: Mattheus Riccius; 6 October 1552 – 11 May 1610), was an Italian Jesuit priest and one of the founding figures of the Jesuit China missions. He created the Kunyu Wanguo Quantu, a 1602 map of the world written in Chinese characters. He is considered a Servant of God by the Catholic Church.

Ricci arrived at the Portuguese settlement of Macau in 1582 where he began his missionary work in China. He became the first European to enter the Forbidden City of Beijing in 1601 when invited by the Wanli Emperor, who sought his services in matters such as court astronomy and calendrical science. He converted several prominent Chinese officials to Catholicism. He also worked with several Chinese elites, such as Xu Guangqi, in translating Euclid's Elements into Chinese as well as the Confucian classics into Latin for the first time in history.
