Domenico had grown tired of his friend's archæological impieties. It gave him no satisfaction to pour out wine, burn incense, arrange garlands, and even cut the throats of animals according to a correct Pagan ritual. It was nothing to him that Horace and Ovid and Tibullus should have done alike. He was a good Christian, never doubting for a moment the power of the Blessed Virgin, the saints, and even the smallest and meanest priest, nor the heat of hell-fire. But he wanted to have the secret of antique proportions, and he was convinced that this secret could be communicated only by a Pagan divinity, just as certain theological mysteries, such as the use of the rosary, had been revealed to the saints by Christ or the Virgin. The Pagan gods were devils, and to hold communication with devils was mortal sin and sure damnation. But lots of people communicated with devils for much more paltry motives, for greed of gold or love of woman, and were yet saved by the intercession of some heavenly patron, or found it worth while not to be saved at all. Domenico, like them, put the question of salvation behind him. He might think of that afterwards, when he had possessed himself of the proportion of the ancients. At all events, at present he was willing to risk everything in order to attain that. He was determined to see that god of the heathens, not as he had seen him once in the house of Messer Neri Altoviti, cut out of marble, but alive, moving, speaking; for _that_ was the god. The god was a devil. Now it is well known that there is a way of compelling every devil to show himself, providing you use sufficiently strong spells. They had sacrificed goats and lambs enough, also doves, and had burned perfumes, and spilt wine sufficient for one of Cardinal Riario's suppers. It was evidently not that sort of sacrifice which would rejoice the god or compel him to show himself. For weeks and weeks Domenico ruminated over the subject. And little by little the logical, inevitable answer dawned upon his horrified but determined mind. For what was the sacrifice which witches and warlocks notoriously offered their Master? The place could not be better chosen. This church was full, every one knew, of demons, who were certainly none other than the gods of the heathen, as Tertullian, Lactantius, Athenagoras, Justin Martyr, and all those other holy doctors had written. It was deserted, its keys in the hands of Cardinal Capranica's confidential architect and decorator; and there were masses being said every holiday to scare the evil spirits. The sacrament was frequently left on the altar.
