We came to know each other at a ceremony in our Temple in the dark. It was the Bull-Killing,'Parnesius explained to Puck.
'I see, said Puck, and turned to the children. 'That's something you wouldn't quite understand. Parnesius means he met Pertinax in church.'
'Yes - in the Cave we first met, and we were both raised to the Degree of Gryphons together.' Parnesius lifted his hand towards his neck for an instant. 'He had been on the Wall two years, and knew the Picts well. He taught me first how to take Heather.'
'What's that?' said Dan.
'Going out hunting in the Pict country with a tame Pict.
You are quite safe so long as you are his guest, and wear a sprig of heather where it can be seen. If you went alone you would surely be killed, if you were not smothered first in the bogs. Only the Picts know their way about those black and hidden bogs. Old Allo, the one-eyed, withered little Pict from whom we bought our ponies, was our special friend. At first we went only to escape from the terrible town, and to talk together about our homes. Then he showed us how to hunt wolves and those great red deer with horns like Jewish candlesticks.
The Roman-born officers rather looked down on us for doing this, but we preferred the heather to their amusements.
Believe me,' Parnesius turned again to Dan, 'a boy is safe from all things that really harm when he is astride a pony or after a deer. Do you remember, O Faun,' - he turned to Puck - 'the little altar I built to the Sylvan Pan by the pine-forest beyond the brook?'
'Which? The stone one with the line from Xenophon?' said Puck, in quite a new voice.
'No! What do I know of Xenophon? That was Pertinax - after he had shot his first mountain-hare with an arrow - by chance! Mine I made of round pebbles, in memory of my first bear. It took me one happy day to build.'
Parnesius faced the children quickly.
'And that was how we lived on the Wall for two years - a little scuffling with the Picts, and a great deal of hunting with old Allo in the Pict country. He called us his children sometimes, and we were fond of him and his barbarians, though we never let them paint us Pict-fashion. The marks endure till you die.'
'How's it done?' said Dan. 'Anything like tattooing?'
'They prick the skin till the blood runs, and rub in coloured juices. Allo was painted blue, green, and red from his forehead to his ankles. He said it was part of his religion. He told us about his religion (Pertinax was always interested in such things), and as we came to know him well, he told us what was happening in Britain behind the Wall. Many things took place behind us in those days. And by the Light of the Sun,' said Parnesius, earnestly, 'there was not much that those little people did not know! He told me when Maximus crossed over to Gaul, after he had made himself Emperor of Britain, and what troops and emigrants he had taken with him. We did not get the news on the Wall till fifteen days later. He told me what troops Maximus was taking out of Britain every month to help him to conquer Gaul; and I always found the numbers were as he said. Wonderful! And I tell another strange thing!'
He joined his hands across his knees, and leaned his head on the curve of the shield behind him.
'Late in the summer, when the first frosts begin and the Picts kill their bees, we three rode out after wolf with some new hounds. Rutilianus, our General, had given us ten days' leave, and we had pushed beyond the Second Wall - beyond the Province of Valentia - into the higher hills, where there are not even any of old Rome's ruins.
We killed a she-wolf before noon, and while Allo was skinning her he looked up and said to me, "When you are Captain of the Wall, my child, you won't be able to do this any more!"
'I might as well have been made Prefect of Lower Gaul, so I laughed and said, "Wait till I am Captain."
"'No, don't wait," said Allo. "Take my advice and go home - both of you."
"'We have no homes," said Pertinax. "You know that as well as we do . We're finished men - thumbs down against both of us. Only men without hope would risk their necks on your ponies."
The old man laughed one of those short Pict laughs - like a fox barking on a frosty night. "I'm fond of you two," he said.
"Besides, I've taught you what little you know about hunting. Take my advice and go home."
"'We can't," I said. "I'm out of favour with my General, for one thing; and for another, Pertinax has an uncle."
"'I don't know about his uncle," said Allo, "but the trouble with you, Parnesius, is that your General thinks well of you."
"'Roma Dea!" said Pertinax, sitting up. "What can you guess what Maximus thinks, you old horse-coper?"
'Just then (you know how near the brutes creep when one is eating?) a great dog-wolf jumped out behind us, and away our rested hounds tore after him, with us at their tails. He ran us far out of any country we'd ever heard of, straight as an arrow till sunset, towards the sunset. We came at last to long capes stretching into winding waters, and on a grey beach below us we saw ships drawn up. Forty-seven we counted - not Roman galleys but the raven-winged ships from the North where Rome does not rule. Men moved in the ships, and the sun flashed on their helmets - winged helmets of the red-haired men from the North where Rome does not rule. We watched, and we counted, and we wondered, for though we had heard rumours concerning these Winged Hats, as the Picts called them, never before had we looked upon them.
"'Come away! come away!" said Allo. "My Heather won't protect you here. We shall all be killed!" His legs trembled like his voice. Back we went - back across the heather under the moon, till it was nearly morning, and our poor beasts stumbled on some ruins.
'When we woke, very stiff and cold, Allo was mixing the meal and water. One does not light fires in the Pict country except near a village. The little men are always signalling to each other with smokes, and a strange smoke brings them out buzzing like bees. They can sting, too!
"'What we saw last night was a trading-station," said Allo. "Nothing but a trading-station. "
