The Book of Wonder by Lord Dunsany

The child that played about the terraces and gardens in sight of the Surrey hills never knew that it was he that should come to the Ultimate City, never knew that he should see the Under Pits, the barbicans and the holy minarets of the mightiest city known. I think of him now as a child with a little red watering-can going about the gardens on a summer's day that lit the warm south country, his imagination delighted with all tales of quite little adventures, and all the while there was reserved for him that feat at which men wonder.

Looking in other directions, away from the Surrey hills, through all his infancy he saw that precipice that, wall above wall and mountain above mountain, stands at the edge of the World, and in perpetual twilight alone with the Moon and the Sun holds up the inconceivable City of Never. To tread its streets he was destined; prophecy knew it. He had the magic halter, and a worn old rope it was; an old wayfaring woman had given it to him: it had the power to hold any animal whose race had never known captivity, such as the unicorn, the hippogriff Pegasus, dragons and wyverns; but with a lion, giraffe, camel or horse it was useless.
