As a student at the University of Rostock he participated in a duel against his third cousin Tycho Brahe in which he cut off most of his nose. The two later became good friends, and he married Tycho's distant cousin Anne Pedersdatter Brahe (1578-1633). Parsberg was lord to Hagesholm. When, in a funeral oration for Brahe, an allusion was made to their unfortunate duel, Parsberg protested and sought redress
Paul Wittich Paul Wittich Paul Wittich (c.1546 – 9 January 1586) was a German mathematician and astronomer whose Capellan geoheliocentric model, in which the inner planets Mercury and Venus orbit the sun but the outer planets Mars, Jupiter and Saturn orbit the Earth, may have directly inspired Tycho Brahe's more radically heliocentric geoheliocentric model in which all the 5 known primary planets orbited the Sun, which in turn orbited the stationary Earth. Wittich was born in Breslau (Wrocław), Silesia, and studied at the universities of Leipzig, Wittenberg and Frankfurt/Oder. About 1580 Wittich stayed with Tycho Brahe on his island Hven in Öresund,
