"I presume he takes yours," retorted Giovanni, regretting that he could not instantly find a sharper answer, for he was not quick-witted though he was suspicious.
"He needs neither yours nor mine," said Marietta, "and he trusts whom he pleases."
"You seem inclined to defend his servants when they are insolent," answered Giovanni.
"For that matter, Zorzi is quite able to defend himself!" She turned her back on her brother and went towards the stairs, taking Nella with her.
Giovanni glanced at her with annoyance and walked along the footway in the direction of his own glass-house, glad to go back to a place where he was absolute despot. But he had been really surprised that Marietta should boldly take the Dalmatian's side against him, and his narrow brain brooded upon the unexpected circumstance. Besides the dislike he felt for the young artist, his small pride resented the thought that his sister, who was to marry a Contarini, should condescend to the defence of a servant.
Zorzi went his way calmly and spent the day in the laboratory. He was in a frame of mind in which such speeches as Giovanni's could make but little impression upon him, sensitive though he naturally was. Really great sorrows, or great joys or great emotions, make smaller ones almost impossible for the time. Men of vast ambition, whose deeds are already moving the world and making history, are sometimes as easily annoyed by trifles as a nervous woman; but he who knows that what is dearest to him is slipping from his hold, or has just been taken, is half paralysed in his sense of outward things. His own mind alone has power to give him a momentary relief.
Herein lies one of the strongest problems of human nature. We say with assurance that the mind rules the body, we feel that the spirit in some way overshadows and includes the mind. Yet if this were really true the spirit—that is, the will—should have power against bodily pain, but not against moral suffering except with some help from a higher source. But it is otherwise. If the will of ordinary human beings could hypnotise the body against material sensation, the credit due to those brave believers in all ages who have suffered cruel torments for their faith would be singularly diminished. If the mind could dominate matter by ordinary concentration of thought, a bad toothache should have no effect upon the delicate imagination of the poet, and Napoleon would not have lost the decisive battle of his life by a fit of indigestion, as has been asserted.
On the other hand, there was never yet a man of genius, or even of great talent, who was not aware that the most acute moral anguish can be momentarily forgotten, as if it did not exist for the time, by concentrating the mind upon its accustomed and favourite kind of work. Johnson wrote Rasselas to pay for the funeral of his yet unburied mother, and Johnson was a man of heart if ever one lived; he could not have written the book if he had had a headache. Saints and ascetics without end and of many persuasions have resorted to bodily pain as a means of deadening the imagination and exalting the will or spirit. Some great thinkers have been invalids, but in every case their food, work has been done when they were temporarily free from pain. Perhaps the truth is on the side of those mystics who say that although the mind is of a higher nature than matter, it is so closely involved with it that neither can get away from the other, and that both together tend to shut out the spirit and to forget its existence, which is a perpetual reproach to them; and any ordinary intellectual effort being produced by the joint activity of mind and the matter through which the mind acts, the condition of the spirit at the time has little or no effect upon them, nor upon what they are doing. And if one would carry the little theory further, one might find that the greatest works of genius have been produced when the effort of mind and matter has taken place under the inspiration of the spirit, so that all three were momentarily involved together. But such thoughts lead far, and it may be that they profit little. The best which a man means to do is generally better than the best he does, and it is perhaps the best he is capable of doing.
Be these things as they may, Zorzi worked hard in the laboratory, minutely carrying out the instructions he had received, but reasoning upon them with a freshness and keenness of thought of which his master was no longer capable. When he had made the trials and had added the new ingredients for future ones, he began to think out methods of his own which had suggested themselves to him of late, but which he had never been able to try. But though he had the furnace to himself, to use as long as he could endure the heat of the advancing summer, he was face to face with a difficulty that seemed insuperable.
The furnace had but three crucibles, each of which contained one of the mixtures by means of which he and Beroviero were trying to produce the famous red glass. In order to begin to make glass in his own way, it was necessary that one of the three should be emptied, but unless he disobeyed his orders this was out of the question. In his train of thought and longing to try what he felt sure must succeed, he had forgotten the obstacle. The check brought him back to himself, and he walked disconsolately up and down the long room by the side of the furnace.
