Giovanni Pierluigi da Palestrina
Giovanni Pierluigi da Palestrina ( 1525 – 2 February 1594) was an Italian Renaissance composer of sacred music and the best-known 16th-century representative of the Roman School of musical composition. He had a lasting influence on the development of church music, and his work is considered as the culmination of Renaissance polyphony.
Christian mysticism
The influences of Greek thought are apparent in the earliest Christian mystics and their writings. Plato (428–348 BC) is considered the most important of ancient philosophers, and his philosophical system provides the basis of most later mystical forms. Plotinus (c. 205 – 270 AD) provided the non-Christian, neo-Platonic basis for much Christian, Jewish and Islamic mysticism.
