On a spectacular journey through Renaissance Italy, Andrew Graham-Dixon searches for the shadowy figure who wrote one of the most important books on art and looks at some dazzling works, including masterpieces of the early Renaissance by Giotto, Masaccio and Donatello. Giorgio Vasari was the grandaddy of all art critics, travelling Italy in the 16th century for his definitive Lives of the Artists. It was a time of miracles that he named 'the Renaissance'.

Andrew Graham-Dixon retraces Vasari's footsteps for this captivating two-part film in a short Art of Italy season. He's an enthusiastic guide, lapsing easily into Italian conversation with the custodians of galleries and chapels who allow him a private view. From Brunelleschi's Duomo in Florence to less familiar marvels - a Donatello sculpture; Masaccio frescoes - he illustrates how rapidly ideas developed. A final treat for him - and us - is a tour of the Vasari Corridor, a rarely accessed gallery that zigzags across the Florentine rooftops.

When ancient architects completed construction on the Great Pyramid at Giza, they left behind the greatest riddle of the engineering world—how did builders lift limestone blocks weighing an average of two and a half tons 480 feet up onto the top of the Pyramid? For centuries, adventurers and Egyptologists have crawled through every passageway and chamber of the Pyramid, measuring and collecting data in an attempt to determine how it was built. For the first time, a revolutionary theory argues that the answer may be inside the Pyramid. Architect Jean-Pierre Houdin and Egyptologist Bob Brier use 3-D software to unlock the secret.

Travelling from the unique Muslim contribution in the medieval south, Andrew Graham-Dixon immerses himself in true Spanish culture and meets the people who live and work with this artistic legacy. He looks at Muslim political and cultural influence as he travels from Cordoba to Granada, seeing classic buildings such as the Great Mosque in Cordoba, the Alcazar in Seville and the Alhambra in Granada. He also shows how the Moors introduced new foods – including citrus fruits, coffee and spices

Graham-Dixon reveals how the north of the country has produced some of the most dazzling and iconic art of the modern age. Spain's turbulent history has shaped artists from Francisco Goya to Pablo Picasso. Graham-Dixon argues that Spanish architecture is the art form now taking the nation forward in the new millennium.

Graham-Dixon journeys to the country’s scorched centre to explore Spanish art of the 16th and 17th centuries. From the mystical world of El Greco to the tender genius of Velazquez, this was a moment so extraordinary it became known as the Golden Age. But beneath the glittering surface was a dark and savage heart. Travelling from the architectural jewel of Toledo to majestic Madrid, Andrew Graham-Dixon traces the rise and fall of the Spanish Empire, the brutal conquest of the New World, and the religious madness of the Inquisition, to discover how a history so violent could produce some of the most beautiful art ever seen.
