"Drawn by curiosity and eager desire, wishing to see the various and strange shapes made by nature, I wandered some distance among gloomy, overhanging rocks, coming to the entrance of a large cave. I stood in front of it for some time, kneeling and shading my eyes, stupefied and amazed, for I did not have prior knowledge of its existence. Suddenly, two things arose in me - fear and desire. Fear of the menacing darkness of the cave, and desire to see if there was any marvelous thing inside it."
{From the notebook of Leonardo Da Vinci}
