==Biography== Valentin Stanzel was born to a German family in [[Olomouc, Moravia]].<ref name="appleton">{{Cite Appletons'|wstitle=Stansel, Valentine|year=1900}}</ref><ref name="CE">{{CathEncy|wstitle=Valentin Stansel}}</ref> He entered the [[Society of Jesus]] on 1 October 1637, and taught rhetoric and mathematics at [[University of Olomouc]] and in [[Prague]]. After being ordained, he requested an appointment to the Jesuit mission in India, and went to Portugal to await an opportunity of taking ship for his destination. Meantime, he lectured on astronomy at the [[University of Évora|college of Évora]]. While there, in order to conform to the language of the country, he changed his name to the form "Estancel", in which form it appears on the title pages of most of his published works.

He was unable to procure passage to India, traveling instead to Brazil, where he was attached to the Jesuit College and Seminary of [[Salvador, Bahia]], as professor of Moral Theology. He also later served as the institution's Superior. At the same time he continued his astronomical work, and made extensive observations, particularly on [[comet]]s, the results of which he was sending to Europe for publication.

On 5 March 1668 Valentin Stanzel discovered a bright comet.<ref>[http://articles.adsabs.harvard.edu//full/2002JBAA..112...13E/0000021.000.html Journal of the British Astronomical Association, vol.112, no.1, p. 21]</ref> His observations of the comet of 1668 are mentioned in [[Isaac Newton|Newton's]] Principia.

Valentin Stanzel died in [[Salvador, Bahia]], Brazil.
