'Thames: Sacred River', by the bestselling author of 'London: The Biography', is about the river from source to sea. It covers history from prehistoric times to the present; the flora of the river; paintings and photographs inspired by the Thames; its geology, smells and colour; its literature, laws and landscapes; its magic and myths; its architecture, trade and weather. This book meanders gloriously, rather as the river does itself: here are Toad of Toad Hall and Julius Caesar, Henry VIII and Shelley, Turner and Three Men in a Boat. The reader learns about the fishes that swam in the river and the boats that plied on its surface; about floods and tides; hauntings and suicides; sewers, miasmas and malaria; locks, weirs and embankments; bridges, docks and palaces. All the towns and villages along the river's 215-mile length are described. Peter Ackroyd has a genius for digging out the most surprising and entertaining details, and for writing about them in the most magisterial prose.
