The Illustrated Complete Works of H.P. Lovecraft

(the continuous band arrangement being frequently interrupted in these late carvings) depicting a constantly growing migration to the nearest refuges of greater warmth—some fleeing to cities under the sea off the far-away coast, and some clambering down through networks of limestone caverns in the hollow hills to the neighbouring black abyss of subterrene waters.
    In the end it seems to have been the neighbouring abyss which received the greatest colonisation. This was partly due, no doubt, to the traditional sacredness of this especial region; but may have been more conclusively determined by the opportunities it gave for continuing the use of the great temples on the honeycombed mountains, and for retaining the vast land city as a place of summer residence and base of communication with various mines. The linkage of old and new abodes was made more effective by means of several gradings and improvements along the connecting routes, including the chiselling of numerous direct tunnels from the ancient metropolis to the black abyss—sharply down-pointing tunnels whose mouths we carefully drew, according to our most thoughtful estimates, on the guide map we were compiling. It was obvious that at least two of these tunnels lay within a reasonable exploring distance of where we were; both being on the mountainward edge of the city, one less than a quarter-mile toward the ancient river-course, and the other perhaps twice that distance in the opposite direction.
    The abyss, it seems, had shelving shores of dry land at certain places; but the Old Ones built their new city under water—no doubt because of its greater certainty of uniform warmth. The depth of the hidden sea appears to have been very great, so that the earth’s internal heat could ensure its habitability for an indefinite period. The beings seem to have had no trouble in adapting themselves to part-time—and eventually, of course, whole-time—residence under water; since they had never allowed their gill systems to atrophy. There were many sculptures which shewed how they had always frequently visited their submarine kinsfolk elsewhere, and how they had habitually bathed on the deep bottom of their great river. The darkness of inner earth could likewise have been no deterrent to a race accustomed to long antarctic nights.
    Decadent though their style undoubtedly was, these latest carvings had a truly epic quality where they told of the building of the new city in the cavern sea. The Old Ones had gone about it scientifically; quarrying insoluble rocks from the heart of the honeycombed mountains, and employing expert workers from the nearest submarine city to perform the construction according to the best methods. These workers brought with them all that was necessary to establish the new venture—shoggoth-tissue from which to breed stone-lifters and subsequent beasts of burden for the cavern city, and other protoplasmic matter to mould into phosphorescent organisms for lighting purposes.
    At last a mighty metropolis rose on the bottom of that Stygian sea; its architecture much like that of the city above, and its workmanship displaying relatively little decadence because of the precise mathematical element inherent in building operations. The newly bred shoggoths grew to enormous size and singular intelligence, and were represented as taking and executing orders with marvellous quickness. They seemed to converse with the Old Ones by mimicking their voices—a sort of musical piping over a wide range, if poor Lake’s dissection had indicated aright—and to work more from spoken commands than from hypnotic suggestions as in earlier times. They were, however, kept in admirable control. The phosphorescent organisms supplied light with vast effectiveness, and doubtless atoned for the loss of the familiar polar auroras of the outer-world night.
    Art and decoration were pursued, though of course with a certain decadence. The Old Ones seemed to realise this falling off themselves; and in many cases anticipated the policy of Constantine the Great by transplanting especially fine blocks of ancient carving from their land city, just as the emperor, in a similar age of decline, stripped Greece and Asia of their finest art to give his new Byzantine capital greater splendours than its own people could create. That the transfer of sculptured blocks had not been more extensive, was doubtless owing to the fact that the land city was not at first wholly abandoned. By
