Adventure thriller set in Renaissance Italy starring Leonardo da Vinci as a young apprentice who witnesses a murder and becomes involved in a plot to take over the city.

Painter, architect, scientist, inventor—Leonardo da Vinci ranks as history's consummate innovator. Consumed with a boundless desire for knowledge, he investigated technical challenges that were hundreds of years ahead of his time. The power of flight was a particular source of fascination for him, and his close studies of bird anatomy and movement informed his development of the ornithopter — a winged, human-powered aircraft. With Leonardo's da Vinci's Flying Machine, you can create a fully working model of the inventor's amazing creation. This self-contained model kit features a 48-page book with details from Leonardo's notebooks plus full-color, easily joined components. Once assembled, the wings flap by turning a crank. Like the prototype, your model won't actually fly, but you'll have an amazing replica of one of the Renaissance genius's most famous futuristic inventions.

"From 1501 to 1505, Leonardo da Vinci and Michelangelo Buonarroti both lived and worked in Florence. Leonardo was a charming, handsome fifty year-old at the peak of his career. Michelangelo was a temperamental sculptor in his mid-twenties, desperate to make a name for himself. The two despise each other."--Front jacket flap.

The legendary Renaissance man and amateur sleuth is back in this exciting follow-up to The Queen's Gambit. As court engineer to the Duke of Milan, Leonardo da Vinci turns his superior mind to a variety of pursuits-from painting to solving the occasional murder. After the deaths of two female servants, Leonardo asks his apprentice, Dino, to go undercover disguised as a woman in the service of the Duke's ward, Contessa Caterina. This should be easy enough, given that "Dino" is in reality Delfina, a young woman masquerading as a boy to serve as Leonardo's apprentice. Delfina is soon torn between her loyalty to Leonardo and her growing feelings for Gregorio, the handsome captain of the Duke's guard. But if what the Contessa's tarot cards foretold is correct, Delfina might be destined to lose her heart...and perhaps her life.

This fascinating book will be of as much interest to engineers as to art historians, examining as it does the evolution of machine design methodology from the Renaissance to the Age of Machines in the 19th century. It provides detailed analysis, comparing design concepts of engineers of the 15th century Renaissance and the 19th century age of machines from a workshop tradition to the rational scientific discipline used today.

A singular fatality has ruled the destiny of nearly all the most famous of Leonardo da Vinci's works. Two of the three most important were never completed, obstacles having arisen during his life-time, which obliged him to leave them unfinished; namely the Sforza Monument and the Wall-painting of the Battle of Anghiari, while the third—the picture of the Last Supper at Milan—has suffered irremediable injury from decay and the repeated restorations to which it was recklessly subjected during the XVIIth and XVIIIth centuries. Nevertheless, no other picture of the Renaissance has become so wellknown and popular through copies of every description. Vasari says, and rightly, in his Life of Leonardo, "that he laboured much more by his word than in fact or by deed", and the biographer evidently had in his mind the numerous works in Manuscript which have been preserved to this day. To us, now, it seems almost inexplicable that these valuable and interesting original texts should have remained so long unpublished, and indeed forgotten. It is certain that during the XVIth and XVIIth centuries their exceptional value was highly appreciated. This is proved not merely by the prices which they commanded, but also by the exceptional interest which has been attached to the change of ownership of merely a few pages of Manuscript. That, notwithstanding this eagerness to possess the Manuscripts, their contents remained a mystery, can only be accounted for by the many and great difficulties attending the task of deciphering them. The handwriting is so peculiar that it requires considerable practice to read even a few detached phrases, much more to solve with any certainty the numerous difficulties of alternative readings, and to master the sense as a connected whole. Vasari observes with reference to Leonardos writing: "he wrote backwards, in rude characters, and with the left hand, so that any one who is not practised in reading them, cannot understand them". The aid of a mirror in reading reversed handwriting appears to me available only for a first experimental reading. Speaking from my own experience, the persistent use of it is too fatiguing and inconvenient to be practically advisable, considering the enormous mass of Manuscripts to be deciphered. And as, after all, Leonardo's handwriting runs backwards just as all Oriental character runs backwards—that is to say from right to left—the difficulty of reading direct from the writing is not insuperable. This obvious peculiarity in the writing is not, however, by any means the only obstacle in the way of mastering the text. Leonardo made use of an orthography peculiar to himself; he had a fashion of amalgamating several short words into one long one, or, again, he would quite arbitrarily divide a long word into two separate halves; added to this there is no punctuation whatever to regulate the division and construction of the sentences, nor are there any accents—and the reader may imagine that such difficulties were almost sufficient to make the task seem a desperate one to a beginner. It is therefore not surprising that the good intentions of some of Leonardo s most reverent admirers should have failed.
