Helisaeus Roeslin
Helisäus Roeslin ( born January 17, 1545 Plieningen; † August 14, 1616 in Buchsweiler ) was a German physician, astrologer, and geographer chronologist.
Life
Roeslin was born in 1544 or 1545 in Plieningen near Stuttgart. His father was probably the local Protestant minister. A ducal scholarship enabled him to attend high school in Stuttgart, before he went to Tübingen in 1561, to study under Samuel Eisenmenger medicine. In 1569 he earned his Ph.D., settled in Pforzheim and established a medical practice. In 1570 he married Judith Beurlin, the daughter of the theologian Jacob Beurlin. As a personal physician, he served since 1572 the Count Palatine Johann Georg I. (Pfalz - Veldenz ) and since 1612 Johann Reinhard von Hanau- Lichtenberg. More, he had special interest in questions of astrology, chronology and geography. From observations of the supernova in 1572 and the comet of 1577, he located the opposite Aristotelian conceptions beyond the lunar orbit, he joined the Middle of the Apocalypse, the occurrence of which he calculated to 1654. Since 1582 he was city physician of Haguenau, where he lived for the longest time. To 1588 he met in Strasbourg on Nicolaus Reimers, called Ursus, and disputed with him about astronomical matters. Roeslin died in 1616 Buchsweiler an der Ruhr.
Geoheliozentrisches model
Roeslin, who did not consider himself a Astronomus, trying to establish his own model of the world in relation to the theories of Ursus and Kepler. In his 1597 published book De opere Dei he discussed the world systems of Ptolemy, Copernicus, Brahe and Ursus and tried to distance themselves from this. Starting from the fact that in his time no parallax of the fixed stars was observed, inferred Roeslin that the stars would have an immense distance from the planet orbits at a heliocentric world view, which he held for physical reasons impossible. He instead went on the assumption that the solid crystal spheres each of which drives the next inner spheres mechanically, thus causing the planetary motions. For this reason Roeslin held the earth to be the center of the finite and limited universe to the moon and sun circles the sun but again for the center of the planetary orbits. The sphere of fixed stars, he introduced himself in constant motion, while he rejected the theory of the self-rotation of the earth. Unlike Johannes Kepler he held also at the idea of perfect circular orbits. His model thus resembles the Tychonic worldview.
