Tell me if anything was ever done. - Leonardo da Vinci

For once you have tasted flight you will walk the Earth with your eyes turned skywards, for there you have been and there you will long to return.

O mighty and once living instrument of formative nature. Incapable of availing thyself of thy vast strength thou hast to abandon a life of stillness and to obey the law which God and time gave to procreative nature.

Non appena nasce la virtù, nasce contro di lei l'invidia, e farà prima il corpo a perdere la sua ombra che la virtù la sua invidia.
