The details of one such night's amusement have been preserved by the contemporary novelist, Celio Malespini,[176] who is well known to have drawn all his materials from real history, and whose book may be accepted as a perfectly accurate and trustworthy picture of the manners of the time. Bianca's brother, Vittorio Cappello, was expected to arrive in Florence with other Venetian gentlemen, and the diversion in question was prepared for their especial delectation. The Grand Duke, however, appears to have taken his full share in the performances. There was at that time, we are told, a necromancer at Florence, who was one of the most powerful performers in his profession. The garden had been placed by Bianca at his disposition, and the sovereign and court were invited by her to disport themselves as follows. "When the hour was come, the Grand Duke and his companions repaired to the garden and walked in the shade, waiting till the necromancer should have completed his preparations. At last he came forth clad in a most extraordinary manner, but quite in keeping with his character. On his head was a mitre covered with pentagons and all sorts of extravagant figures, so that he appeared a veritable new Zoroaster. With slow and stately steps he advanced to a spot prepared for the purpose, and there drew a circle on the sward with a knife. This circle corresponded in size with a cavity which had previously been prepared beneath the surface of the soil; and around he drew with the knife a quantity of mystic signs, which, however, nobody saw, inasmuch as the place was all covered with herbage. But this was done," says the shrewd Malespini, merely for appearance sake,—'_per dare colore all'arrosto_.' "This done, he fenced the circle around with a piece of a ship's cable, leaving a narrow entrance, at which was placed a moderate sized bell. On the right hand were two large brasiers filled with burning coals; and on the left a filbert wand, and a vase full of drugs for fumigations. When all this was arranged, he brought the Grand Duke and the rest within the circle, imposing on them silence with solemn gestures; and then requested that one among them would stand forward and assist him in doing what was needed, assuring them, very seriously, that no harm should happen to him."
