And when the Count said, ‘Stay and sup with me,’ the rustic answered, ‘My Lord, I wish to go home before it rains; for infallibly there will be much rain today.’ The Count, wondering at him, sent for Guido Bonatti, as a great astrologer, and said to him, ‘Dost thou hear what this man says?’ Guido answered, ‘He does not know what he is saying; but wait a little.’ Guido went to his study, and, having taken his astrolabe, observed the aspect of the heavens. And on returning he said that it was impossible it should rain that day. But the rustic obstinately affirming what he had said, Guido asked him, ‘How dost thou know?’ The rustic answered, ‘Because today my ass, in coming out of the stable, shook his head and pricked up his ears, and whenever he does this, it is a certain sign that the weather will soon change.’ Then Guido replied, ‘Supposing this to be so, how dost thou know there will be much rain?’ ‘Because,’ said he, ‘my ass, with his ears pricked up, turned his head aside, and wheeled about more than usual.’ Then, with the Count’s leave, the rustic departed in haste, much fearing the rain, though the weather was very clear. And an hour afterwards, lo, it began to thunder, and there was a great down-pouring of waters, like a deluge.
