“The turtle moves.”

“The place where the story happened was a world on the back of four elephants perched on the shell of a giant turtle. That's the advantage of space. It's big enough to hold practically anything, and so, eventually, it does.People think that it is strange to have a turtle ten thousand miles long and an elephant more than two thousand miles tall, which just shows that the human brain is ill-adapted for thinking and was probably originally designed for cooling the blood. It believes mere size is amazing.There's nothing amazing about size. Turtles are amazing, and elephants are quite astonishing. But the fact that there's a big turtle is far less amazing than the fact that there is a turtle anywhere.”

“It was all very well going on about pure logic and how the universe was ruled by logic and the harmony of numbers, but the plain fact of the matter was that the Disc was manifestly traversing space on the back of a giant turtle and the gods had a habit of going round to atheists' houses and smashing their windows.”

“The world rides through space on the back of a turtle. This is one of the great ancient world myths, found wherever men and turtles were gathered together; the four elephants were an Indo-European sophistication. The idea has been lying in the lumber rooms of legend for centuries. All I had to do was grab it and run away before the alarms went off.There are no maps. You can't map a sense of humour. Anyway, what is a fantasy map but a space beyond which There Be Dragons? On the Discworld we know There Be Dragons Everywhere. They might not all have scales and forked tongues, but they Be Here all right, grinning and jostling and trying to sell you souvenirs.”

“He moved on, in the centre of a widening circle. He wasn't an enemy, he was a nemesis.”

“He moved in a way that suggested he was attempting the world speed record for the nonchalant walk.”

“REMIND ME AGAIN, he said, HOW THE LITTLE HORSE-SHAPED ONES MOVE.”
