Donât be nosy.â Grandpa never talked about this at all. When Hayley asked where he had been, he pretended not to hear. But she was always truly glad when he came back. The house felt very dreary without the background hum of the computers and the constant ringing or beeping of all the phones.So, as soon as Grandmaâs bedroom door shut, Hayley raced softly downstairs to the computer room.
Grandpa was there, sitting massively in front of a screen, carefully following something on it with a light-pen. Hayley tiptoed up to look over his shoulder. It was a picture of Earth, slowly spinning in dark blue emptiness. She saw Africa rotating past as she arrived. But Africa was quite hard to see because it and the whole globe was swathed in a soft, multicoloured mist. The mist seemed to be made up of thousands of tiny pale threads, all of them moving and swirling outwards. Each thread shone as it moved, gentle and pearly, so the effect was as if Earth spun in a luminous rainbow veil. While Hayley watched, some of the threads wrapped themselves together into a shining skein and this grew on outwards, growing brighter and harder-looking as it grew, and then got thrown gently sideways with the turning of the world, so that it became a silver red spiral. There were dozens of these skeins, when Hayley looked closely, in dozens of silvery colours. But underneath these were thousands of other shining threads which busily drifted and wove and plaited close to Earth.
âThatâs beautiful !â Hayley said. âWhat are they?â
âAre your hands clean?â Grandpa answered absently. His light-pen steadily picked out a gold gleaming set of threads underneath the spirals and followed it in and out, here and there, through the gauzy mass. He seemed to take it for granted that Hayley had washed her hands because he went on, âThis is the mythosphere. Itâs made up of all the stories, theories and beliefs, legends, myths and hopes, that are generated here on Earth. As you can see, itâs constantly growing and moving as people invent new tales to tell or find new things to believe. The older strands move out to become these spirals, where things tend to become quite crude and dangerous. Theyâve hardened off, you see.â
âAre they real, the same as atoms and planets?â Hayley asked.
âQuite as real â even realler in some ways,â Grandpa replied.
Hayley said the name of it to herself, in order not to forget it. âThe mythosphere. And what are you doing with it?â
âTracing the golden apples,â Grandpa said. âWondering why theyâve never become a spiral of their own. They mix into other strands all the time. Look.â He did something to the keyboard to make Earth turn about and spread itself into a flat plain with continents slowly twirling across it. Golden threads rose from India, from the flatness north of the mountains, from the Mediterranean and from Sweden, Norway and Britain. âSee here.â Grandpaâs big hairy hand pointed the light-pen this way and that as the threads arose. âThis thread mingles with three different dragon stories. And thisâ¦â the line of light moved southward ââ¦mixes with two quite different stories here. This oneâs the judgement of Paris and here we have Atalanta, the girl who was distracted from winning a race by some golden apples. And there are hundreds of folk talesâ¦â The pen moved northwards to golden threads growing like grass over Europe and Asia. Grandpa shook his head. âGolden apples all over. They cause death and eternal life and danger and choices. They must be important. But none of them combine. None of them spiral and harden. I donât know why.â
âIf theyâre real,â Hayley said, âcan a person go and walk in them, or are they like germs and atoms and too small to see?â
âOh, yes,â Grandpa said, frowning at the
