col lor rapido corso
Men will seem to see new destructions in the sky. The flames that fall from it will seem to rise in it and to fly from it with terror. They will hear animals of every kind speak in human language. They will instantaneously run in person in various parts of the world, without movement. They will see the greatest splendour in the midst of darkness. O! marvel the human race! What frenzy has led you thus! You will speak with animals of every species and they with you in human speech. You will see yourself fall from great heights without any harm, and torrents will accompany you, and will mingle in their rapid course...
And many others will be deprived of their store and their food, and will be cruelly submerged and drowned by folks devoid of reason. Oh Justice of God! Why dost thou not wake and behold thy creatures thus ill used?
Of writing Letters from one Country to another
Men will speak with each other from the most remote countries, and reply.
