The Globe tells the story of humanity's quest to discover the form of the world. Philosophers in ancient Greece deduced the true shape of the Earth in the fourth century BCE; the Romans passed the knowledge to India, and from there it spread to Baghdad and Central Asia.

In early medieval Europe, Christians debated the matter but long before the time of Columbus, the Catholic Church had accepted that the Earth is round and not flat. However, it wasn't until the seventeenth century that Jesuit missionaries finally convinced the Chinese that their traditional square-earth cosmology was mistaken.

An accessible challenge to long-established beliefs about the history of ideas, The Globe shows how the realisation that our planet is a sphere deserves to be considered the first great scientific achievement.

'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

'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.' - Bookseller
