"Nay! nay! Messer Doria," returned Bocca, "the lady Moon is too round and bright for so black a gallant. If you would know his mistresses, they be here. Here he comes to find them in their bed, where he is less like to be stung of fleas than of scorpions."

"Fie! Out upon the vile necromancer!" exclaimed Messer Giordano, crossing himself; "see what learning leads to! Folk disown God, and go fornicating in Pagan graveyards."

Leaning against the Church wall, Messer Guido let the riders have their say. When he judged they had voided all the froth of their shallow brains over him:

"Gentle cavaliers," he answered, smiling, "you are at home. I am your host, and courtesy constrains me to receive your insults without reply."

So saying, he bounded over the tombs and walked quietly away. The horsemen looked at one another in amazement; then bursting out laughing, they gave spur to their steeds. As they were galloping along the Peretola Road, Messer Bocca said to Messer Betto:

"Who can doubt now but this Guido is gone mad? He told us we were at home in the graveyard. And to say such a thing, he must needs have lost his wits."

"True it is," replied Messer Betto, "I cannot imagine what he meant to have us understand by talking in such a sort. But he is used to expressing himself in dark sayings and subtle parables. He hath tossed us a bone this time must be opened to find the marrow."

"Pardi!" ejaculated Messer Giordano; "my dog may have this bone to gnaw, and the Pagan that threw it to boot."

They soon reached the banks of the Peretola brook, whence the cranes may be seen rising in flocks at daybreak. During the chase, which was abundantly successful, Messer Betto Brunelleschi never ceased pondering the words Guido had used. And by dint of much thinking, he discovered their signification. Hailing Messer Bocca with loud cries, he said to him:

"Come hither, Messer Bocca! I have just guessed what it was Messer Guido meant us to understand. He told us we were at home in a graveyard, because the ignorant be for all the world like dead men, who, according to the Epicurean doctrine, have no faculty of thought or knowledge."
