CHAPTER I
A VOYAGE IN THE SKY
INTRODUCTION
IT WAS at Venice. The lofty windows of the ancient Ducal Palace of the Speranzi opened upon the Grand Canal. The orb of night was mirrored in the waters by a furrow of silver spangles, and the immensity of the sky stretched over the towers and cupolas.
When the musicians borne by the gondolas had turned the corner of the canal to glide towards the Bridge of Sighs, their last choruses vanished in the night, and Venice seemed to go to sleep in that profound silence known to no hive of humanity but the Queen of the Adriatic. This Venetian silence was untroubled save by the cadenced beats of the old clock, and perhaps I should not have appreciated the whole depth of the universal muteness but for the regular oscillation of that apparatus designed for measuring time. The continuous “tick-tock” marked out the silence, and, curiously enough, seemed to intensify it.
Seated in the embrasure of the high window, I contemplated the shining disc of the Moon enthroned in an azure sky filled entirely with its light, and I remembered that this luminary of the night, so tranquil and calm in appearance, moved a thousand yards in space at each beat of the clock. This fact struck me for the first time with a certain force, perhaps on account of the enveloping solitude.
Gazing upon the lunar globe, in which I could distinguish with the naked eye the ancient seas and geographical outlines, I bethought myself that it was still perhaps inhabited by beings organised differently from ourselves who can live in an extremely rarefied atmosphere; but what struck me even more forcibly was its rapid revolution round the Earth, at the rate of 1,000 yards at each beat of the clock, making 38 miles a minute, 2,280 an hour, 53,800 a day, or 1,500,000 miles for each lunar month.
I saw in my mind the Moon revolving round us from west to east in less than a month, and at the same time I felt, so to speak, the daily movement of the Earth about its axis, also from west to east, which makes the sky appear to move in the opposite direction. While I was still reflecting, indeed, the Moon had actually shifted and descended in the west towards the steeple of the Chiesa. These terrestrial and celestial movements, softer than those of the gondolas gliding on the limpid waters, bear us along through reality as through a dream. They measure the days and the years as we pass, like fleeting shadows, while they endure for ever. The silent Moon, sphinx of the sky, shone already on the waters silvered by her splendour millions of years ago, while terrestrial humanity was still awaiting its slow unfolding in the limbo of future possibilities. Strange animals peopled the forests which covered the continents, fantastic fishes pursued each other in the floods, vampires clove the air, and two-footed crocodiles, which seem to be the ancestors of those of Egyptian mythology, showed themselves in the clearings on the banks of the rivers. Later the same Moon shone on the birth of the flowers, on the nests of the first birds. But how many nights had she not illuminated with pale beams before the first glance from a human eye fell upon her, before the first human thought ascended towards her! To-night she shines upon a populous and active humanity, flourishing cities, marble palaces, built amid the clouds. Just now, at my feet, in a gondola a pair of lovers called upon her to witness their eternal vows, forgetting that her rapid phases are the symbol of our changefulness and our shortness of life. Yes, she has been the confidante of many mysteries, and for a long time yet will radiant youth sing under her sky its eternal song of love. But one day, a poor, enfeebled lamp, she will only shine upon a cemetery of ice; there will be no more clocks for measuring hours nor human beings to count them. Thus I mused, in the bright moonlight which seemed to intensify all the shadows and to deepen all the abysses between the palaces plunging into the black water. This neighbouring world exists at a distance of 240,000 miles from us. Our thoughts fly thither in a flash. With the speed of light, the distance is covered in 1⅓ second. In imagination I took flight up to the distant luminary. I forgot Venice, the Adriatic, and the Earth, and I felt myself carried beyond the confines of the terrestrial atmosphere.
