In the green country of Esca, between the white mountains and the grey sea, the kings have always kept a garden. It lay within walls of stone older than the kingdom, and in it grew every good thing the gods had given that land: the lily and the bitter herb, the apple and the thorn, the slow oak and the quick bean, water in a stone channel and fish in the water. The garden belonged to the king, as the kingdom belonged to the king, and as the king belonged to the gods who had anointed him. And it was kept, in the king’s name, by a man called Naum.

Naum had tended it through the reigns of three kings, and through the lean and lordless years between the last of them and the next, when the throne stood empty and men did as they pleased. In those years he had learned what he believed to be the first truth of all keeping: that everything left to itself runs to ruin, and that the work of a good keeper is to set a wall against ruin and hold it. So he squared the beds and graveled the paths and pruned each tree to the shape that bore best, and he hung cages in the branches and kept in them the small seed-eating birds, that they might not strip what he had sown. Under his hand the garden was orderly and full and quiet, and he was proud of the quiet.

Then the boy was anointed king.

He was eight years old. The priests poured the oil upon his head and the gods set their authority upon him, and from that hour grown men knelt to a child, and his word was law in Esca though his voice had not yet broken. Naum, who had counseled kings before the boy’s grandfather was born, knelt with the rest. This was the order of things, and Naum loved order.

The king’s name was Cael, and that first summer he came often to the garden, for it was his. He went down the gravel paths touching everything, and Naum walked behind him naming what he touched, glad to teach. But the boy stopped beneath the cages, where the small birds beat against the withes, and he asked why they were shut up. To keep them from the seed, said Naum. The boy looked a long while at the birds. Then he said, Let them out.

Naum told him, gently, what would come of it: the seed gone, the beds bare, the autumn poor. He spoke as one speaks to a child. But the boy was the king, and the king is not bound to be persuaded; he has only to be obeyed. Let them out, he said again, and there was in the child’s flat voice the whole weight of the gods who had anointed him. So Naum opened the cages with his own hands, because the king had commanded it, and because that too was the order of things.

The birds went up into the garden like thrown seed. And they ate. They stripped the sown beds and the ripening beds; they took the seed of the white lilies that the old queen, Cael’s mother, dead in his infancy, had set in the earth with her own hands — the only thing of her left growing in the world. By autumn that quarter of the garden was bare brown earth, and the lilies did not come again, not that year nor after.

The boy wept when he understood. He had not known that a word, once let go, could no more be caught and caged than a bird. He had learned the thing every king must learn: that he is answerable, and that what authority looses upon the world it cannot always call back. Naum grieved with him for the lilies. But in his heart Naum thought, I was right. Order is the wall against ruin, and the child has tasted what comes of breaching it. He believed he had taught the boy a lesson.

The freed birds did not leave the garden. They nested in the old wild oak by the wall, the one tree Naum had never pruned, and there they stayed, and bred, season upon season — a small wild flock in the king’s ordered garden.

The years went by as years do, and Cael grew tall, and Esca went on under his hand and Naum’s. Naum kept the garden as he had always kept it, more strictly now, for the loss of the lilies sat in him like a proof: see what comes of the unbound thing. And the young king let him keep it so, for the most part, and learned the names of the herbs, and grew toward his manhood.

In the king’s sixteenth year a blight came on the country. It was no sickness of the leaf but a plague of the small grey moth, whose grubs came in their thousands and devoured all green things, and they came into the garden over the grey wall as though it were not there. Naum knew this enemy. He had read of it, and he had a remedy, and the remedy was order: cut and burn the infested quarter to bare earth, net the rest, prune every tree to the quick so the grubs had nowhere to lie, and ration what was saved against a hungry year. A wall against ruin. He brought this counsel to the king.

But the king walked out into the garden and looked — not at the grubs, but at the old wild oak, where the small birds the boy had freed eight years before were waking to the feast. And he said, No. Do not burn it, and do not net it. Leave it. Naum argued. He spoke of the lilies; he spoke of the lordless years; he spoke as the wise speak to the young. The king heard him out, for Cael was no longer a child and had learned to listen even though he might not bend. Then he said only, The birds are hungry. Leave them their meat.

So nothing was cut and nothing was burned, against all of Naum’s counsel and all of his fear. And the wild flock fell upon the grey moth and its grubs and ate, and ate, and were joined by others of their kind out of the country round, for word travels among birds as it does among men; and in a fortnight the plague that no net would have held and no fire would have stopped was gone out of the garden, and the garden was green. The thing Naum had cursed and would have killed eight years before had grown, in long time and by no design of any man, into the one thing that could save the king’s garden in the year of the moth.

That same hungry season the king did another thing Naum thought madness: he had the garden gates thrown open and let the people of the town come in and take of the fruit, that none should starve while the king ate behind a wall. Naum’s granaries fed them too — his order was not nothing; it was the grain in the storehouses that carried Esca through the want, and the king knew it and said so. But it was the open gate the people remembered, and the green garden, and the wild birds singing in it; and the love they bore the king after that year was a living thing, and no wall had ever bought its like.

Naum was an old man by then, and he had been wrong, and he knew it. He sat down on a stone bench in the green garden and was quiet a long while. He had spent his life believing that the keeper’s work was to hold a wall against the wild. He saw now that he had mistaken the wall for the garden.

Cael came into his full manhood and was a good king, which is to say a true keeper. He pruned, but he pruned for the fruit and not for the shape. He kept the walls, but he set wide gates in them. He held the sword the gods had given him, but he held it for the garden and not for himself. Under him Esca grew the way the garden grew, orderly and wild at once, peaceful and teeming, a tended thing that was nonetheless alive. Men came from other countries to see it and went away unable to say what they had seen, for it was neither the wilderness, where the strong eat the weak and nothing is safe, nor the cage, where nothing is eaten and nothing grows. It was a garden. There is no other word, and the word is older than Esca.

Naum grew very old. In his last spring the king had him carried out on a litter, for his legs would no longer bear him, and set in the shade of the old wild oak where the birds were. Naum looked at the garden he had kept for sixty years and three kings, and saw that he no longer knew it. The squared beds had softened; the gravel paths wandered; wild things he would once have pulled grew up among the sown, and bore, and the whole of it hummed with bees and birds and the small unbidden life he had spent his strength to keep out. And he saw that it was good — better than his quiet had ever been — and he was not grieved by this, but glad, and ashamed of his old gladness in the quiet.

He said to the king, I kept it wrong.

The king said, You kept it as long as it needed keeping that way. And he showed Naum a thing Naum had passed ten thousand times and never understood. Against the south wall grew an old grapevine that Naum himself had planted as a young man and trained upon a frame of cedar withes, tying it to the wood year by year. The vine had long since grown over the frame entirely; you could not see the cedar for the leaves and the heavy fruit; the trellis was wholly hidden, and the vine stood beside it though no longer upon it.

Naum, said the king, the trellis is not the vine. But there is no vine without it. You were the trellis. It was never wrong that the wood came first.

And Naum understood then, at the end, the thing he had been too orderly to see: that order is not life, but the frame that lets life climb; that the wall is for the garden and not the garden for the wall; and that the gods, who had set their authority upon a weeping child and worked their will through a freed flock of birds, do not keep the world as a man keeps a quiet room. They keep it as a good gardener keeps a garden — tending, pruning, walling, and then standing back, near at hand but not too near, to let the green thing do the one thing that walls and shears can never do: grow.

He died not long after, in the garden, and was buried beneath the wild oak, and the king grieved for him truly.

In the years that followed, the king’s own son — who would be anointed king after him while still a boy, for in Esca authority was given by the gods and not earned by years — played in the garden as Cael had played. One evening the child climbed the old oak, up among the nests of the wild birds, higher than was wise, and called out for his father to see. The king watched from the path below. He did not call the boy down, nor climb to fetch him, nor forbid the climbing. He stood near, where he could be reached if he were needed, and watched his son climb the tree in the living garden in the last of the light.
