The Last Enchantment - Mary Stewart [185]
When I had last been in Segontium, that great military city built and fortified by Maximus whom the Welsh call Macsen, it had been all but a ruin. Since then, Cador of Cornwall had repaired and re-fortified it against attackers from Ireland. That had been many years ago, but more recently Arthur had seen to it that Maelgon, his commander in the west, kept it in repair. I was interested to see what had been done, and how; and this, as much as anything else, took me along the valley track. Soon I was well above the town. It was a day of sunshine and chilly wind, and the city lay bright and washed with colour below me in the arm of the dark-blue sea. Beside the track the fortress walls rose stout and well kept, and within them I could hear the clash and bustle of an alert and well-maintained garrison. As if I had still been Arthur's engineer, proposing to report to him, I marked all that I saw. Then I came to the south side of the fortress, where ruin and the four winds had been allowed their way, and paused to look up the valley slope toward Macsen's Tower.
There was the track, once trodden by the faithful legionnaires, but probably now used only by sheep or goats and their herds. It led up the steep hillside to the swell of stony turf that hid the ancient, underground shrine of Mithras. For more than a hundred years the place had been ruinous, but when I had been there before, the steps that led down to the entrance had still been passable, and the temple itself, though patently unsafe, still recognizable. I started slowly up the track, wondering why, after all, I had come to see it again.
I need not have wondered. It was not there. There was no sign either of the mound that had hidden the roof or of the steps that had led downward. I did not need to look far to find the cause. At the head of the slope where the temple had lain, the restorers of Segontium, levering away the great stones of the fortress wall for their rebuilding, and quarrying here and there for smaller metal, had set half the hillside rolling in a long slope of scree. In this had seeded and grown half a hundred small trees -- thorn and ash and blackberry -- so that even the track of the fallen scree was hard to trace. And everywhere, like the weft of a loom, the narrow sheep-trods, white with summer dust, criss-crossed the hillside.
I seemed to hear again, faintly, the receding voice of the god.
"Throw down my altar. It is time to throw it down."
Altar, shrine and all, had vanished into the locked depths of the hill.

There is something not quite believable about any change of this kind. I stood there for some time, casting about for the bearings I knew. There was no question of the accuracy of my memory; a line straight from Macsen's Tower on the hill above to the southwest corner of the old fortress, and another, from the Commandant's house to the distant peak of Y Wyddfa, would intersect one another right over the site of the shrine. Now, they intersected one another right in the middle of the scree. I could see where, almost at that very point, the bushes were sparse, and the boulders showed gaps between, as of a space below.
"Lost something?" asked a voice.
I looked round. A boy was sitting perched above me, on a fallen block of stone. He was very young, perhaps ten years old, and very dirty. He was tousled and half-naked, and was chewing a hunk of barley bread. A hazel stick lay near him, and his sheep grazed placidly a little way up the hill.
"A treasure, it seems," I said.
"What kind of treasure? Gold?"
"It might be. Why?"
He swallowed the last bit of bread. "What's it worth to you?"
"Oh, half my kingdom. Were you going to help me find it?"
"I've found gold here before."
"You have?"
"Aye. And once a silver penny. And once a belt buckle. Bronze, that was."
"It seems
