Johann Christoph Demantius

Johann Christoph Demantius (15 December 1567 – 20 April 1643) was a German composer, music theorist, writer and poet. He was an exact contemporary of Monteverdi, and represented a transitional phase in German Lutheran music from the polyphonic Renaissance style to the early Baroque. He was born in Reichenberg (now Liberec, in the Czech Republic, north of Prague near the border with Germany), and probably received his early training there, though little information is available about his early life.
