Xióng Sānbá 熊三拔 / Sabatino de Ursis, S.J.
Italian Jesuit. Born Ponzano di Lecce (Kingdom of Naples), 1575; died Macao, 3 May 1620. The Chinese name Xióng Sānbá renders “[Saba]tino [de Ur]sis” by phonetic approximation: Xióng 熊 (bear) is a punning translation of Latin ursus (the de Ursis family name).
Joined the Society of Jesus 1597; sent to the Asia missions, arriving Macao 1606; reached Beijing 1607 to assist Matteo Ricci 利瑪竇 (利瑪竇) at the Beijing residence. Trained in mathematics and natural philosophy at the Roman College under Christopher Clavius (Ricci’s own teacher) — possessed strong technical competence in observational astronomy and instrument construction. After Ricci’s death in May 1610 he succeeded as the principal Jesuit voice in mathematical astronomy at the Beijing court, collaborating with Xú Guāngqǐ 徐光啟 in particular.
In 1611, when the Bureau of Astronomy’s failure to predict a solar eclipse touched off renewed calendar-reform debate, the Ministry of Rites memorialized for a Western-style reform (the proposal that would eventually produce the Chóngzhēn lìshū 崇禎曆書 of 1629–1635); de Ursis with Xú Guāngqǐ and Lǐ Zhīzǎo 李之藻 prepared the technical foundations. The Jiǎnpíng yí shuō 簡平儀說 (KR3f0011) — his translation of the European astrolabium catholicum (the simplified planispheric astrolabe), to which Xú Guāngqǐ contributed the preface dated Wànlì xīnhài (1611) — provided the basic instrument-of-observation; the Biǎo dù shuō 表度說 (KR3f0010) of Wànlì jiǎyín (1614), translated and brushed-down with Zhōu Zǐyú 周子愚, provided the elementary gnomon-shadow theory; the Tàixī shuǐfǎ 泰西水法 of Wànlì 40 (1612), with Xú Guāngqǐ, provided European hydraulic engineering for irrigation reform.
After the Nánjīng anti-Christian persecution of 1616 (the Shěn Què 沈㴶 affair) he was deported with the other Jesuits to Macao, where he died four years later. His Beijing astronomical work was continued — and superseded — by the next generation of Jesuit astronomers (Adam Schall von Bell, Giacomo Rho) in the Chóngzhēn lìshū project of the late 1620s and 1630s.
