Now in paperback, The Globe traces humanity’s quest to understand the true shape of the Earth. Ancient Greek philosophers identified it as spherical in the fourth century BCE, with this knowledge spreading via Rome, India, and Central Asia. The Catholic Church accepted a round Earth well before Columbus, yet Jesuit missionaries only persuaded the Chinese to abandon their square-earth cosmology in the seventeenth century. Challenging traditional views on intellectual history, The Globe argues that recognising Earth’s spherical nature was humanity’s first major scientific breakthrough. Compelling and thought-provoking, the book explores how this discovery reshaped global perspectives across centuries.
A tour d’horizon that spans time as well as space, this is a thrilling intellectual adventure story. * Tom Holland, author of Dominion: The Making of the Western Mind *
In an age of globalisation, James Hannam’s playful and erudite book reminds us of the global origins of our common understanding of the spherical earth, stretching from Babylon to NASA. A truly all-encompassing book: a wonderful achievement and a delight to read. * Jerry Brotton, author of A History of the World in Twelve Maps *
An exploration of one of humankind’s oldest and most profound insights, The Globe is a work of compulsively readable myth-busting. As amiable as it is scholarly, James Hannam’s book uses the history of the spherical Earth to provide a global tour of cosmologies through the ages. * Philip Ball, author of The Book of Minds *
From the philosophers of ancient Greece to seventh-century Jesuit missionaries to China, the story of humanity’s quest to discover the form of our world, and how we came to know that the Earth is round and not flat. -- Caroline Sanderson * The Bookseller *
Hannam gives us context and biography, when available . . . The virtue of Hannam’s writing style is that it is almost invisible. The reader does not have to untangle sentences, as often in academic prose, nor does the author plant the meadows of his pages with rare and distracting lexicographic blooms. As for the arc of his history, it swept me along, especially when I found I was learning a thing or two . . . Bede called Pliny’s Natural History - “that delightful book” - and the same could be said of Hannam’s own lively historical journey.” -- Christopher Howse * The Daily Telegraph *
This splendid book . . . aims mainly to dismantle 'the conflict theory' - the idea that a battle between science and religious literalism prevented people accepting the roundness of the Earth well into the 15th century . . . After a colourful tour through ancient Babylonian, Egyptian and Persian cosmologies, we arrive at the Greeks, who at last began to figure things out. -- Steven Poole * The Spectator *
From philosophers in ancient Greece to Jesuit missionaries in China, James Hannam’s The Globe explores the history of ideas and our quest to understand our planet. * People's Friend: 'We're Loving' *
James Hannam’s The Globe takes us on a whirlwind 2,000-year tour d’horizon of how the counter-intuitive theory of a round world became accepted as scientific fact . . . Hannam has been able to encapsulate such a wide range of historical sources into an enjoyable, fast-paced narrative. Those whose scholarly appetites have been whetted can consult the comprehensive and well-chosen bibliography for follow-up reading . . . [The Globe is] a rollicking scientific-historical adventure. -- Charlotte Gauthier * The Critic *
The story of what James Hannam calls "humanity's first great scientific achievement" is more complicated – and interesting – than you might have imagined. Through 23 chapters packed with compelling personalities, Hannam whizzes us around the globe between historical conceptions of our planet, from ancient Mesopotamia (a round disc) via ancient China (a square set in a spherical heaven) to our modern oblate spheroid . . . He brings to thrilling life centuries of intense debate and disagreement - the fertile ground on which science grows. -- Seb Falk * BBC History *
Give the gift of science . . . James Hannam’s The Globe celebrates our first great scientific achievement: realising, thousands of years ago and against all intuition, that Earth is a a ball floating in space. -- Simon Ings * New Scientist, ‘Best Non-Fiction and Popular Science Books of 2023' *
This fascinating chronicle by historian Hannam traces how humanity’s understanding of Earth’s shape has changed over millennia . . . The trivia captivates (the prevailing view under China’s Han dynasty claimed "the sky was round and the Earth was square"), offering a globe-trotting tour of how a major scientific breakthrough made its way across the world. Readers will be enlightened. * Publishers Weekly *
