Although Leonardo's Giant Crossbow is one of his most popular
drawings, it has been one of the least understood. "Leonardo's
Giant Crossbow" offers the first in-depth account of this drawing's
likely purpose and its highly resolved design. This fascinating
book has a wealth of technical information about the Giant Crossbow
drawing, as it's a complete study of this project, though this is
as accessible to the general audience as much as it is also
informative with new discoveries for the professors of engineering,
technology and art. The book explores the context of Leonardo's
invention with an examination of the extensive documentary
evidence, a short history of the great crossbow and ballista, the
first accurate translation of the text and the technical
specifications, and a detailed analysis of Leonardo's design
process for the crossbow, from start to finish. Dozens of
preparatory drawings, along with the recent discovery of nearly
invisible metal stylus preparatory incisions under the ink of the
Giant Crossbow drawing, are evidence of Leonardo's intent to offer
engineers and other viewers a thorough design of the massive
machine. The book proposes these new discoveries with the help of a
strategy that had been at the core of Leonardo's working
philosophy: the proportional method. As proven with an analysis of
the Giant Crossbow project, he used a consistent approach to 1/3rd
proportions throughout the design and drawing process and employed
this kind of proportional strategy at the start of almost every
important project. Thanks to this proof of his knowledge of
geometry, evidence of his studies of impetus and force, and thanks
to the highly polished and complex nature of the Giant Crossbow
design, a later date for the drawing is proposed in the present
book, associating the drawing with his drafting capabilities around
1490-93.
