Welcome to Litsy!

Under a Metal Sky examines the wonders and perils that the earth's precious metals have offered humans, forever changing our relationship with the world around us The ground beneath our feet is full of riches: the ochre that allowed prehistoric humans to paint on the cave walls; the tin that drove the early Industrial Revolution; radium, the source of Marie Curie's wonder; and lithium, the essential mineral of modern life found in our mobile phones and laptops. Each of these minerals has a story to tell, and each has its place in the broader story of human history. Under a Metal Sky takes us on a journey across the peat-rich Dutch lowlands, through Prague and Bohemia, and on to the gold-rich mountains of Georgia. Along the way, Marsden uncovers the strange and colorful histories of alchemy, scientific revolution, industrialization, and technological innovation, peopled by figures like the Habsburg Emperor Rudolf II, Goethe, Marie Curie, and William Blake. But alongside wonder and inspiration, there has also been plunder and heedless exploitation, the consequences of which have set us on a path towards our own extinction. Beautifully written and mind-expanding, Under a Metal Sky seamlessly blends travel writing, cultural history, and geology. Who knew the history of rocks could be so page turning?
