Johannes Stadius

Johannes Stadius or Estadius ( Dutch Jan Van Ostaeyen ; French Jean Stade ) (born April 19, 1527 , † June 17, 1579 ) was an astronomer , astrologer and mathematician from Flanders .

Life

Jan Van Ostaeyen came from Loenhout , which is why he is also known as Leonnouthesius . He studied mathematics , geography and history at the University of Leuven with Gemma R. Frisius . From 1554 he worked in Turin with the Duke of Savoy Emanuel Philibert , then in Paris , Cologne and Brussels . In his Tabulae Bergenses (1560) he also describes himself as the court mathematician of Philip of Spain .

In Brussels he published Ephemerides novae at auctae , edited by Arnold Birckmann, Cologne, 1554. The Ephemerides (Greek ephemeros , daily) list the positions of the stars.

The work, read by Tycho Brahe and Nostradamus , links mathematics and medicine. Stadius was encouraged to do this by his teacher Gemma Frisius - he should not hesitate like Nicolaus Copernicus and not be afraid to give up the outdated Alfonsin tables in favor of his own knowledge.

He died in Paris , according to the epitaph on June 17th, 1579 at the age of 52 years and almost 2 months, which is why his date of birth was estimated to be May 1st, 1527.

The lunar crater Stadius was named after him.
