The Age of Wonder is a colorful and utterly absorbing history of the men and women whose discoveries and inventions at the end of the eighteenth century gave birth to the Romantic Age of Science.

When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook in search of new worlds. Other voyages of discovery—astronomical, chemical, poetical, philosophical—swiftly follow in Richard Holmes's thrilling evocation of the second scientific revolution.

Through the lives of William Herschel and his sister Caroline, who forever changed the public conception of the solar system; of Humphry Davy, whose near-suicidal gas experiments revolutionized chemistry; and of the great Romantic writers, from Mary Shelley to Coleridge and Keats, who were inspired by the scientific breakthroughs of their day, Holmes brings to life the era in which we first realized both the awe-inspiring and the frightening possibilities of science—an era whose consequences are with us still.

I, Hasan the son of Muhammad the weigh-master, I, Jean-Leon de Medici, circumcised at the hand of a barber and baptized at the hand of a pope, I am now called the African, but I am not from Africa, nor from Europe, nor from Arabia. I am also called the Granadan, the Fassi, the Zayyati, but I come from no country, from no city, no tribe.

I am the son of the road, my country is the caravan, my life the most unexpected of voyages.

Thus wrote Leo Africanus, in his fortieth year, in this imaginary autobiography of the famous geographer, adventurer, and scholar Hasan al-Wazzan, who was born in Granada in 1488. His family fled the Inquisition and took him to the city of Fez, in North Africa. Hasan became an itinerant merchant, and made many journeys to the East, journeys rich in adventure and observation.

He was captured by a Sicilian pirate and taken back to Rome as a gift to Pope Leo X, who baptized him Johannes Leo. While in Rome, he wrote the first trilingual dictionary (Latin, Arabic and Hebrew), as well as his celebrated Description of Africa, for which he is still remembered as Leo Africanus.
