As is well-known, Clarke moved to Ceylon/Sri Lanka in 1956 -- in large part for the year-around access to diving -- and remained there until his death. The locale inspired at least one of Clarke's novels, Fountains of Paradise:
Clarke lived in Sri Lanka from 1956 until his death in 2008, having emigrated there when it was still called Ceylon, first in Unawatuna on the south coast, and then in Colombo. Clarke held citizenship of both the UK and Sri Lanka. He was an avid scuba diver and a member of the Underwater Explorers Club. Living in Sri Lanka afforded him the opportunity to visit the ocean year-round. It also inspired the locale for his novel The Fountains of Paradise in which he described a space elevator. This, he believed, ultimately will be his legacy, more so than geostationary satellites, once space elevators make space shuttles obsolete. (link)
I first read The Fountains of Paradise many years ago, and I pulled it off the shelf this afternoon for a refresher. There is an intense opening, set in the classical period, 2000 years ago, involving a "Prince Kalidasa," who does not seem to resemble the actual Kalidasa (who was not a prince, but a poet). And there are some rich descriptions of the island of Sri Lanka (named "Taprobane" -- Tap-ROB-a-nee -- by Clarke).
Here are a few paragraphs from the historical section involving Clarke's Prince Kalidasa:
The air was so clear today that Kalidasa could see the temple, dwarfed by distance to a tiny white arrowhead on the very summit of Sri Kanda. It did not look like any work of man, and it reminded the king of the still greater mountains he had glimpsed in his youth, when he had been half-guest, half-hostage at the court of Mahinda the Great. All the giants that guarded Mahinda's empire bore such Crests, formed of a dazzling, crystalline substance for which there was no word in the language of Taprobane. The Hindus believed that it was a kind of water, magically transformed, but Kalidasa laughed at such superstitions.
That ivory gleam was only three days' march away - one along the royal road, through forests and paddy-fields, two more up the winding stairway which he could never climb again, because at its end was the only enemy he feared, and could not conquer. Sometimes he envied the pilgrims, when he saw their torches marking a thin line of fire up the face of the mountain. The humblest beggar could greet that holy dawn and receive the blessings of the gods; the ruler of all this land could not.
But he had his consolations, if only for a little while. There, guarded by moat and rampart, lay the pools and fountains and Pleasure Gardens on which he had lavished the wealth of his kingdom. And when he was tired of these, there were the ladies of the rock-the ones of flesh and blood, whom he summoned less and less frequently-and the two hundred changeless immortals with whom he often shared his thoughts, because there were no others he could trust.
Thunder boomed along the western sky. Kalidasa turned away from the brooding menace of the mountain, towards the distant hope of rain. The monsoon was late this season; the artificial lakes that fed the island's complex irrigation system were almost empty. By this time of year he should have seen the glint of water in the mightiest of them all-- which, as he well knew, his subjects still dared to call by his father's name: Paravana Samudra, the Sea of Paravana. It had been completed only thirty years ago, after generations of toil. In happier days, young Prince Kalidasa had stood proudly beside his father, when the great sluice-gates were opened and the life-giving waters had poured out across the thirsty land. In all the kingdom there was no lovelier sight than the gently rippling mirror of that immense, man-made lake, when it reflected the domes and spires of Ranapura, City of Gold-the ancient capital which he had abandoned for his dream.
In this made-up history of the ancient kingdom of Taprobane, Clarke actually seems to know whereof he speaks; the injections of bits of Hindu culture seem to come from a position of knowledge.
And here is a little from the main section of the novel, set in the present day. The protagonist is a Sri Lankan named Raja (short for "Johan Oliver de Alwis Sri Rajasinghe"), who has retired from public life, and moved to an estate built on the site of "Kalidasa's" original pleasure gardens:
That had been twenty years ago, and he had never regretted his decision. Those who predicted that boredom would succeed where the temptations of power had failed did not know their man or understand his origins. He had gone back to the fields and forests of his youth, and was living only a kilometre from the great, brooding rock that had dominated his childhood. Indeed, his villa was actually inside the wide moat that surrounded the Pleasure Gardens, and the fountains that Kalidasa's architect had designed now splashed in Johan's own courtyard, after a silence of two thousand years. The water still flowed in the original stone conduits; nothing had been changed, except that the cisterns high up on the rock were now filled by electric pumps, not relays of sweating slaves.
Securing this history-drenched piece of land for his retirement had given Johan more satisfaction than anything in his whole career, fulfilling a dream that he had never really believed could come true. The achievement had required all his diplomatic skills, plus some delicate blackmail in the Department of Archaeology. Later, questions had been asked in the State Assembly; but fortunately not answered.
He was insulated from all but the most determined tourists and students by an extension of the moat, and screened from their gaze by a thick wall of mutated Ashoka trees, blazing with flowers throughout the year. The trees also supported several families of monkeys, who were amusing to watch but occasionally invaded the villa and made off with any portable objects that took their fancy. Then there would be a brief inter-species war with fire-crackers and recorded danger-cries that distressed the humans at least as much as the simians - who would be back quickly enough, for they had long ago learned that no-one would really harm them.
Reading this, I can't help but think of Clarke himself, one of the world's most famous writers, living in a remote part of Sri Lanka -- away from it all.
After the opening, the novel has a more conventional science fiction story arc -- the goal is to build a kind of massive space elevator from the top of a mountain in Taprobane...
