Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. About the same period the great painter, Leonardo da Vinci, approached the problem in a more scientific spirit, and his notebooks contain several sketches of wings to be fitted to the arms and legs.
