John Chrysostom. John Chrysostom (347 - 407) was a notable Christian bishop and preacher from the 4th and 5th centuries in Syria and Constantinople. He is famous for eloquence in public speaking and his denunciation of abuse of authority in the Church and in the Roman Empire of the time.
Johannes Chrystostomus Wolfgangus Theophilus Mozart (1756â1791) was arguably the most gifted musician in the history of classical music. His inspiration is often described as 'divine', but he worked assiduously, not only to become the great composer he was, but also a conductor, virtuoso pianist, organist and violinist. Mozart's music embraces opera, symphony, concerto, chamber, choral, instrumental and vocal music, revealing an astonishing number of imperishable masterpieces.
