Codex on the Flight of Birds is a relatively short codex from c. 1505 by Leonardo da Vinci. [1] It comprises 18 folios and measures 21 × 15 centimetres. Now held at the Royal Library of Turin, the codex begins with an examination of the flight behavior of birds and proposes mechanisms for flight by machines.
In the 15th century, Leonardo da Vinci published the Codex Leicester, in which he rejected Aristotle's theory and attempted to prove that the only effect of air on a thrown object was to resist its motion, [7] and that air resistance was proportional to flow speed, a false conclusion which was supported by Galileo's 17th century observations of ...
In the 15th-century Leonardo da Vinci created several flying machine designs incorporating aeronautical concepts, but they were unworkable due to the limitations of contemporary knowledge. [2] In the late 18th century, the Montgolfier brothers invented the hot-air balloon which soon led to manned flights.
Leonardo da Vinci studied bird flight for many years, analyzing it rationally and anticipating many principles of aerodynamics. He understood that "An object offers as much resistance to the air as the air does to the object", [ 31 ] anticipating Isaac Newton 's third law of motion (published in 1687).

Designs for flying machines by Leonardo da Vinci, c. 1490. Attempts to fly without any real aeronautical understanding have been made from the earliest times, typically by constructing wings and jumping from a tower with crippling or lethal results. [2] Wiser investigators sought to gain some rational understanding through the study of bird flight.
The Great Kite, Leonardo's flying machine in codex on flight. The Great Kite (Italian: il Grande Nibbio) was a wooden machine designed by Leonardo da Vinci.Leonardo realized it between the end of the 15th Century and the beginning of the 16th Century.
The Vitruvian Man, c. 1490. Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study.
