A chance discovery at a distinguished London map fair in 2012 by a Belgian globe collector produced the most unique of finds: a distinct globe with mysterious images, such as old ships, sailors, a volcano, a hybrid monster, pentimenti, waving patterns, conic individualised mountains, curving rivers, vigorous coastal lines, chiaroscuro and an unresolved triangular anagram, which remains an enigma. The globe is hand-engraved in great detail on ostrich egg shells from Pavia by a left-handed Renaissance genius of unquestionable quality. It shows secret knowledge of the map world from the time of Columbus, Cabral, Amerigo Vespucci and Leonardo da Vinci. Central and North America are covered by a vast ocean. The da Vinci globe originates from Florence and dates from 1504. It marks the first time ever that the names of countries such as Brazil, Germania, Arabia and Judea have appeared on a globe. A Leonardo drawing for this globe, showing the coast of the New World and Africa has been discovered in the British Library. This book brings the reader through a fabulous journey of scholars, maps, riddles, rebuses, iconographic symbols and enigmatic phrases such as HIC SVNT DRACONES to illuminate the da Vinci globe. It details 500 years of mystery, fine scholarship and expert forensic testing at numerous material science laboratories the world over. The da Vinci globe now takes its rightful place, surpassing the Lenox globe, its copper-cast identical twin, as the most mysterious globe of our time. As such, this monograph is an essential text in Leonardo studies and in the history of cartography.

1478 was the year in which Leonardo da Vinci, aged 26, obtained his first official commission and witnessed the Pazzi Conspiracy against the Medici family. In that year, he probably opened his independent workshop, leaving that of his master Andrea del Verrocchio, and, in its final months, he began to paint two paintings representing the Virgin Mary. One of these paintings is very likely the Benois Madonna at the State Hermitage, St. Petersburg; a work that marks a strong change in Leonardo’s style and power of expression and his representation of light and human emotions. This book provides an in-depth analysis of Leonardo’s growth as an artist in this year, detailing his training, his culture, his collaboration with Verrocchio, and his engagement in the artistic and cultural life of 1460s and 1470s Florence.

Milan, 1497: Leonardo da Vinci is completing his masterpiece, The Last Supper. Pope Alexander VI is determined to execute him after realizing that the painting contains clues to a baffling -- and blasphemous -- message, which he is determined to decode. The Holy Grail and the Eucharistic Bread are missing, there is no meat on the table and, shockingly, the apostles are portraits of well-known heretics -- none of them depicted with halos. And why has the artist painted himself into the scene with his back turned toward Jesus? The clues to Leonardo's greatest puzzle are right before your eyes....

Invention and innovation are what distinguish the human race from all of the other species on Earth. Throughout history the imagination and pioneering spirit of human kind has compelled us to question why we do things in a certain way and, more importantly, how we can do things better. Celebrating the ingenuity, creativity and resourcefulness that has led to some of the most amazing technological leaps through the ages, Breverton's Encyclopedia of Inventions examines the key innovations and breakthroughs of all time and the genius behind them. Starting with the building of the pyramids in ancient Egypt and the discovery of the solar system, moving through surgery, dynamite and rockets, to modern technology such as the smart card and genetic engineering, Terry Breverton springs many surprises. He uncovers fascinating and little-known facts: for example, that Price, not Fleming, discovered penicillin; that Swan, not Edison invented the electric light, and that Wallace, not Darwin first advanced the theory of evolution. Tracing the sheer persistence of brilliant men and women across the globe, who fought the prevailing ideas of their times and advanced technology, Breverton's Encyclopedia of Inventions will inspire anyone interested in the history and developments that have changed our lives and shaped our planet's future.

Best-selling author Leonard Shlain explores the life, art, and mind of Leonardo da Vinci, seeking to explain his singularity by looking at his achievements in art, science, psychology, and military strategy and then employing state of the art left-right brain scientific research to explain his universal genius. Shlain shows that no other person in human history has excelled in so many different areas as da Vinci and he peels back the layers to explore the how and the why. Shlain asserts that Leonardo’s genius came from a unique creative ability that allowed him to understand and excel in a wide range of fields. From here Shlain jumps off and discusses the history of and current research on human creativity that involves different modes of thinking and neuroscience .The author also boldly speculates on whether or not the qualities of Leonardo’s brain and his creativity presage the future evolution of the human species. Leonardo’s Brain uses da Vinci as a starting point for an exploration of human creativity. With his lucid style, and his remarkable ability to discern connections in a wide range of fields, Shlain brings the reader into the world of history’s greatest mind. .
