Leonardo da Vinci created the two most famous paintings in history, The Last Supper and the Mona Lisa. But in his own mind, he was just as much a man of science and engineering. With a passion that sometimes became obsessive, he pursued innovative studies of anatomy, fossils, birds, the heart, flying machines, botany, geology, and weaponry.

Graham Hancock's multi-million bestseller Fingerprints of the Gods remains an astonishing, deeply controversial, wide-ranging investigation of the mysteries of our past and the evidence for Earth's lost civilization. Twenty years on, Hancock returns with the sequel to his seminal work filled with completely new scientific and archaeological evidence, which has only recently come to light.

Founded by Alexander the Great and built by self-styled Greek pharaohs, the city of Alexandria at its height dwarfed both Athens and Rome. It was the marvel of its age, legendary for its vast palaces, safe harbors, and magnificent lighthouse. But it was most famous for the astonishing intellectual efflorescence it fostered and the library it produced. If the European Renaissance was the "rebirth" of Western culture, then Alexandria, Egypt, was its birthplace.

The fate of the Lost Ark of the Covenant is one of the great historical mysteries of all time. The Bible contains hundreds of references to the Ark's power, but the Ark itself mysteriously disappears from recorded history sometime after the building of the Temple of Solomon. After 10 years of searching through the dusty archives of Europe and the Middle East, Graham Hancock has succeeded where scores of others have failed. This intrepid journalist has tracked down the true story behind the myths and legends - revealing where the Ark is today, how it got there, and why it remains hidden.

Pulitzer Prize winner Wallace Stegner recounts the remarkable career of Major John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of the Southwest Indian tribes. This classic work is a penetrating and insightful study of the Powell’s career, from the beginning of the Powell Survey, in which Powell and his men famously became the first to descend the Colorado River, to his eventual expulsion from the Geological Survey.

One of the great, but often unmentioned, causes of both happiness and misery is the quality of our environment: the kinds of chairs, walls, buildings, and streets that surround us. And yet, a concern for architecture is too often described as frivolous, even self-indulgent. Alain de Botton starts from the idea that where we are heavily influences who we can be, and argues that it is architecture's task to stand as an eloquent reminder of our full potential.

Early in 1495, Leonardo da Vinci began work in Milan on what would become one of history's most influential and beloved works of art - The Last Supper. After a dozen years at the court of Lodovico Sforza, the Duke of Milan, Leonardo was at a low point personally and professionally: at 43, in an era when he had almost reached the average life expectancy, he had failed, despite a number of prestigious commissions, to complete anything that truly fulfilled his astonishing promise.

Acclaimed British historian Anthony Everitt delivers a compelling account of the former orphan who became Roman emperor in A.D. 117 after the death of his guardian Trajan. Hadrian strengthened Rome by ending territorial expansion and fortifying existing borders. And - except for the uprising he triggered in Judea - his strength-based diplomacy brought peace to the realm after a century of warfare.

Michelangelo, God's Architect is the first book to tell the full story of Michelangelo's final two decades, when the peerless artist refashioned himself into the master architect of St. Peter’s Basilica and other major buildings. When the Pope handed Michelangelo control of the St. Peter’s project in 1546, it was a study in architectural mismanagement, plagued by flawed design and faulty engineering.

How did a simple design error cause one of the great disasters of the 1980s - the collapse of the walkways at the Kansas City Hyatt Regency Hotel? What made the graceful and innovative Tacoma Narrows Bridge twist apart in a mild wind in 1940? How did an oversized waterlily inspire the magnificent Crystal Palace, the crowning achievement of Victorian architecture and engineering? These are some of the failures and successes that Henry Petroski, author of the acclaimed The Pencil, examines in this engaging, wonderfully literate book.

His father conceived of the Brooklyn Bridge, but after John Roebling's sudden death, Washington Roebling built what has become one of American's most iconic structures - as much a part of New York as the Statue of Liberty or the Empire State Building. Yet, as recognizable as the bridge is, its builder is too often forgotten - and his life is of interest far beyond his chosen field. It is the story of immigrants, of the frontier, of the greatest crisis in American history, and of the making of the modern world.

Creativity is in our bones. It is found in our very DNA, something not known to Leonardo da Vinci or anyone else who lived in his day and time. All he did was to uncover the hidden genius which lay within himself, and he used that inner genius to the very best of his abilities. Leonardo da Vinci is best known for some of the world's most masterful paintings, but he was so much more than merely another artist with paints and brushes. Born to a peasant woman in 1452, Leonardo would go on to astound the world he lived in with his artistry and his inventions.

Five hundred and thirty years ago, a young woman sat before a Grecian-nosed artist known as Leonardo da Vinci. Her name was Cecilia Gallerani, and she was the young mistress of Ludovico Sforza, duke of Milan. Sforza was a brutal and clever man who was mindful that Leonardo’s genius would not only capture Cecilia’s beguiling beauty but also reflect the grandeur of his title. But when the portrait was finished, Leonardo’s brush strokes had conveyed something deeper by revealing the essence of Cecilia’s soul.

When Hitler’s armies occupied Italy in 1943, they also seized control of mankind’s greatest cultural treasures. As they had done throughout Europe, the Nazis could now plunder the masterpieces of the Renaissance, the treasures of the Vatican, and the antiquities of the Roman Empire. On the eve of the Allied invasion, General Dwight Eisenhower empowered a new kind of soldier to protect these historic riches. In May 1944 two unlikely American heroes—artist Deane Keller and scholar Fred Hartt—embarked from Naples on the treasure hunt of a lifetime, tracking billions of dollars of missing art, including works by Michelangelo, Donatello, Titian, Caravaggio, and Botticelli.

One day in 1872, self-taught Assyriologist George Smith was sifting through a pile of clay tablets when he realized he was reading about "a flood, storm, a ship caught on a mountain, and a bird sent out in search of dry land". This is the riveting story of the discovery of the world's first literary epic, the "Epic of Gilgamesh".

Traditionally known as a dirty, congested, and dangerous city, 19th Century Paris was transformed in an extraordinary period from 1848 to 1870, when the government launched a huge campaign to build streets, squares, parks, churches, and public buildings. The Louvre Palace was expanded, Notre-Dame Cathedral was restored and the French masterpiece of the Second Empire, the Opra Garnier, was built.

As a reminder of God's role in the history and future of America, Newt and Callista Gingrich give listeners a look into the architecture and beauty of the nation's capital in Rediscovering God in America. Listeners will take a walk through Washington, DC, to view the nation's monuments and memorials, including the National Archives, where Thomas Jefferson's immortal words jump off the page. But this is not simply a walking tour of the city; this is a tour of American history.

Brunelleschi's Dome is the story of how a Renaissance genius bent men, materials, and the very forces of nature to build an architectural wonder we continue to marvel at today. Denounced at first as a madman, Brunelleschi was celebrated at the end as a genius. He engineered the perfect placement of brick and stone, built ingenious hoists and cranes to carry an estimated 70 million pounds hundreds of feet into the air, and designed the workers' platforms and routines so carefully that only one man died during the decades of construction.

It was the splendor and the scandal of the age. In 1506, the ferociously ambitious Renaissance Pope Julius II tore down the most sacred shrine in Europe, the millennium-old St. Peter's Basilica built by the Emperor Constantine over the apostle's grave, to build a better basilica.

In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth - and a central plank of established Christian religion - on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany.

In 1939, a team of workers beneath the Vatican unearthed an early Christian grave. This surprising discovery launched a secret quest that would last decades a quest to discover the long-lost burial place of the Apostle Peter. From earliest times, Christian tradition held that Peter, a lowly fisherman from Galilee, whom Christ made leader of his church was executed in Rome by Emperor Nero and buried on Vatican Hill. But his tomb had been lost to history. Now, funded anonymously by a wealthy American, a small army of workers embarked on the dig of a lifetime.

In this revolutionary book, Joan Breton Connelly challenges our most basic assumptions about the Parthenon and the ancient Athenians. Beginning with the natural environment and its rich mythic associations, she re-creates the development of the Acropolis - the Sacred Rock at the heart of the city-state - from its prehistoric origins to its Periklean glory days as a constellation of temples among which the Parthenon stood supreme.

In 1922, Howard Carter peered into Tutankhamun's tomb for the first time, the only light coming from the candle in his outstretched hand. Urged to tell what he was seeing through the small opening he had cut in the door to the tomb, the Egyptologist famously replied, "I see wonderful things". Carter's fabulous discovery is just one of the many spellbinding stories told in Three Stones Make a Wall.

This monumental book tells the enthralling story of one of the greatest accomplishments in our nation's history, the building of what was then the longest suspension bridge in the world. The Brooklyn Bridge rose out of the expansive era following the Civil War, when Americans believed all things were possible.

In 1508, despite strong advice to the contrary, the powerful Pope Julius II commissioned Michelangelo Buonarroti to paint the ceiling of the newly restored Sistine Chapel in Rome. During the four extraordinary years that Michelangelo spent laboring over the ceiling, power politics and personal rivalries swirled around him. He battled ill health, financial and family difficulties, inadequate knowledge of the art of fresco, and the Pope's impatience - a history that is more compelling than most novels.

The Nile, like all of Egypt, is both timeless and ever-changing. In this audio, renowned Egyptologist Toby Wilkinson takes us on a journey downriver that is both history and travelogue. We begin at the First Nile Cataract, close to the modern city of Aswan. From there, Wilkinson guides us through the illustrious nation birthed by this great river.

Toby Lester, author of the award-winning The Fourth Part of the World, masterfully crafts yet another century-spanning saga of people and ideas in this epic story of Vitruvian Man, Leonardo da Vinci’s iconic drawing of a man inscribed in a circle and a square. Over time, the nearly 550-year-old ink-on-paper sketch has transformed into a collective symbol of the nature of genius, the beauty of the human form, and the universality of the human spirit.

Physical infrastructure in the United States is crumbling. The American Society of Civil Engineers has, in its latest report, given American roads and bridges a grade of D and C+, respectively, and has described roughly 65,000 bridges in the United States as 'structurally deficient'. This crisis - and one need look no further than the I-35W bridge collapse in Minnesota to see that it is indeed a crisis - shows little sign of abating short of a massive change in attitude amongst politicians and the American public.

Jan van Eyck's Ghent Altarpiece is on any art historian's list of the 10 most important paintings ever made. Often referred to by the subject of its central panel, the Adoration of the Mystic Lamb, it represents the fulcrum between the Middle Ages and the Renaissance. It is also the most frequently stolen artwork of all time.

The Path Between the Seas tells the story of the men and women who fought against all odds to fulfill the 400-year-old dream of constructing an aquatic passageway between the Atlantic and Pacific oceans. It is a story of astonishing engineering feats, tremendous medical accomplishments, political power plays, heroic successes, and tragic failures. McCullough expertly weaves the many strands of this momentous event into a captivating tale.
