The focus here is on the growing awareness of the physical, mental and psychological attributes of the individual, and the development of a new philosophy which leads ultimately to Descartes' formulation: cogito ergo sum. A growing awareness of the physical, mental and psychological attributes of the individual leads to a fresh focus on the 'common man' - notably by Shakespeare, but also in their own ways by Caravaggio and by Monteverdi. Spoken theatre and opera are parallel vehicles for expressing and dramatising the human condition and the fluctuations and depths of the human heart. The first public opera house opens in Venice in 1637. Monteverdi, now maestro di cappella at the Basilica of St Mark, is perfectly placed for one final, extraordinary push into this brand-new dramatic world.
