Helisaeus Roeslin

Helisaeus Roeslin or Helisäus Röslin (17 January 1545 – 14 August 1616) was a German physician and astrologer who adopted a geoheliocentric model of the universe. He was one of five observers who concluded that the Great Comet of 1577 was located beyond the moon. His representation of the comet, described as "an interesting, though crude, attempt," was among the earliest and was highly complex.

Life

Roeslin was born in Plieningen (now part of Stuttgart). had known Johannes Kepler since their student days and was one of his correspondents. Roeslin placed more emphasis on astrological predictions than did Kepler, and though he respected Kepler as a History of mathematics#Modern, mathematician, he rejected some of Kepler's cosmological principles, including Copernican heliocentrism, Copernican theory. Kepler criticized Roeslin's predictions in his book ''De stella nova'', on the comet of 1604, and the two kept up their arguments in a series of pamphlets written as dialogues.

Roeslin's 1597 book ''De opere Dei creationis'' is regarded as one of the major works in the late 16th-century controversy over the formulation of a geoheliocentric world system. Robert Burton (scholar), Robert Burton refers to Roeslin in his ''Anatomy of Melancholy''.

Roeslin was physician-in-ordinary to the count palatine of County of Veldenz, Veldenz and the count of List of states in the Holy Roman Empire (H), Hanau-Lichtenberg in Bouxwiller, Bas-Rhin, Buchsweiler in Alsace.

He made a prediction that the world would end in 1654 based on the appearance of a SN 1572, new star in 1572.James Randi, ''The Mask of Nostradamus'' Page 240.

After Roeslin's death at Bouxwiller, Bas-Rhin, Buchsweiler in 1616, his unpublished astrology, theology and kabbalistic work merged into the manuscript collection of Karl Widemann.
