George Frideric Handel’s Messiah is arguably the greatest piece of participatory art ever created. But this work of triumphant joy was born in a worried age. Britain in the early Enlightenment was a place of astonishing creativity but also the seat of an empire mired in war, enslavement, and conflicts over everything. Prize-winning author Charles King has crafted a cinematic drama of the troubled lives that shaped a masterpiece of hope. This book presents a depressive dissenter stirred to action by an ancient prophecy; an actress plagued by an abusive husband and public scorn; an Atlantic sea captain and penniless philanthropist; and an African Muslim man held captive in the American colonies and hatching a dangerous plan for getting back home. At center stage is Handel himself, composer to kings but, at midlife, in ill health and straining to keep an audience’s attention.
