'Leonardo da Vinci,' he replied, 'has this noble sentence: "The hope and desire of returning home to one's former state is like the moth's desire for the light; and the man who with constant longing awaits each new month and new year, deeming that the things he longs for are ever too late in coming, does not perceive that he is longing for his own destruction." How, then, can the pathway which will lead us into the heart of God be other than dangerous? why should you, who are no materialist, cherish the continuity and order of the world as those do who have only the world? You do not value the writers who will express nothing unless their reason understands how it will make what is called the right more easy; why, then, will you deny a like freedom to the supreme art, the art which is the foundation of all arts? Yes, I shall send out of this chapel saints, lovers, rebels and prophets: souls who will surround themselves with peace, as with a nest made with grass; and others over whom I shall weep. The dust shall fall for many years over this little box; and then I shall open it; and the tumults, which are, perhaps, the flames of the last day, shall come from under the lid.'

I did not reason with him that night, because his excitement was great and I feared to make him angry; and when I called at his house a few days later, he was gone and his house was locked up and empty. I have deeply regretted my failure both to combat his heresy and to test the genuineness of his strange book. Since my conversion I have indeed done penance for an error which I was only able to measure after some years.

II

I was walking along one of the Dublin quays, on the side nearest the river, about ten years after our conversation, stopping from time to time to turn over the books upon an old bookstall, and thinking, curiously enough, of the terrible destiny of Michael Robartes, and his brotherhood; when I saw a tall and bent man walking slowly along the other side of the quay. I recognized, with a start, in a lifeless mask with dim eyes, the once resolute and delicate face of Owen Aherne. I crossed the quay quickly, but had not gone many yards before he turned away, as though he had seen me, and hurried down a side street; I followed, but only to lose him among the intricate streets on the north side of the river. During the next few weeks I inquired of everybody who had once known him, but he had made himself known to nobody; and I knocked, without result, at the door of his old house; and had nearly persuaded myself that I was mistaken, when I saw him again in a narrow street behind the Four Courts, and followed him to the door of his house.

I laid my hand on his arm; he turned quite without surprise; and indeed it is possible that to him, whose inner life had soaked up the outer life, a parting of years was a parting from forenoon to afternoon. He stood holding the door half open, as though he would keep me from entering; and would perhaps have parted from me without further words had I not said: 'Owen Aherne, you trusted me once, will you not trust me again, and tell me what has come of the ideas we discussed in this house ten years ago? – but perhaps you have already forgotten them.'

'You have a right to hear,' he said, 'for since I have told you the ideas, I should tell you the extreme danger they contain, or rather the boundless wickedness they contain; but when you have heard this we must part, and part for ever, because I am lost, and must be hidden!'

I followed him through the paved passage, and saw that its corners were choked, and the pictures gray, with dust and cobwebs; and that the dust and cobwebs which covered the ruby and sapphire of the saints on the window had made it very dim. He pointed to where the ivory tablets glimmered faintly in the dimness, and I saw that they were covered with small writing, and went up to them and began to read the writing. It was in Latin, and was an elaborate casuistry, illustrated with many examples, but whether from his own life or from the lives of others I do not know. I had read but a few sentences when I imagined that a faint perfume had begun to fill the room, and turning round asked Owen Aherne if he were lighting the incense.

'No,' he replied, and pointed where the thurible lay rusty and empty on one of the benches; as he spoke the faint perfume seemed to vanish, and I was persuaded I had imagined it.

'Has the philosophy of the Liber Inducens in Evangelium Æternum made you very unhappy?' I said.

'At first I was full of happiness,' he replied, 'for I felt a divine ecstasy, an immortal fire in every passion, in every hope, in every desire, in every dream; and I saw, in the shadows under leaves, in the hollow waters, in the eyes of men and women, its image, as in a mirror; and it was as though I was about to touch the Heart of God. Then all changed and I was full of misery, and I said to myself that I was caught in the glittering folds of an enormous serpent, and was falling with him through a fathomless abyss, and that henceforth the glittering folds were my world; and in my misery it was revealed to me that man can only come to that Heart through the sense of separation from it which we call sin, and I understood that I could not sin, because I had discovered the law of my being, and could only express or fail to express my being, and I understood that God has made a simple and an arbitrary law that we may sin and repent!'

He had sat down on one of the wooden benches and now became silent, his bowed head and hanging arms and listless body having more of dejection than any image I have met with in life or in any art. I went and stood leaning against the altar, and watched him, not knowing what I should say; and I noticed his black closely-buttoned coat, his short hair, and shaven head, which preserved a memory of his priestly ambition, and understood how Catholicism had seized him in the midst of the vertigo he called philosophy; and I noticed his lightless eyes and his earth-coloured complexion, and understood how she had failed to do more than hold him on the margin: and I was full of an anguish of pity.

'It may be,' he went on, 'that the angels whose hearts are shadows of the Divine Heart, and whose bodies are made of the Divine Intellect, may come to where their longing is always by a thirst for the divine ecstasy, the immortal fire, that is in passion, in hope, in desire, in dreams; but we whose hearts perish every moment, and whose bodies melt away like a sigh, must bow and obey!'

I went nearer to him and said: 'Prayer and repentance will make you like other men.'

'No, no,' he said, 'I am not among those for whom Christ died, and this is why I must be hidden. I have a leprosy that even eternity cannot cure. I have seen the whole, and how can I come again to believe that a part is the whole? I have lost my soul because I have looked out of the eyes of the angels.'
