Stich Simon Marius

Simon Marius

Mathematician – Medical Practitioner – Astronomer  

1573 – 1624

Simon Marius from Gunzenhausen, the Ansbach Court Astronomer, discovered the four largest moons of Jupiter at about the same time as Galileo Galilei in 1610, however he only published his book Mundus Iovialis, containing his findings, in 1614, 400 years ago this year.

Accused by Galilei of plagiarism, his reputation suffered permanent damage, in spite of proof brought to light at the beginning of the 20th century that Marius’ research had been entirely his own. A number of events – mainly in the Franconian area – will throw light on his scientific achievements.

This internet presence is intended to be a guide through the anniversary year of 2014 and will bring together electronically retrievable sources, secondary literature, lectures and news on Simon Marius and – whenever possible – provide convenient links. We the initiators invite you the public to make use of this multilingual portal and also to make your own contributions.
