'Gladiators! _That_ sort of game,' he said. 'There were two days' Games in his honour when he landed all unexpected at Segedunum on the East end of the Wall. Yes, the day after we had met him we held two days' games; but I think the greatest risk was run, not by the poor wretches on the sand, but by Maximus. In the old days the Legions kept silence before their Emperor.

So did not we! You could hear the solid roar run West along the Wall as his chair was carried rocking through the crowds. The garrison beat round him-clamouring, clowning, asking for pay, for change of quarters, for anything that came into their wild heads. That chair was like a little boat among waves, dipping and falling, but always rising again after one had shut the eyes.' Parnesius shivered.

'Were they angry with him?' said Dan.

'No more angry than wolves in a cage when their trainer walks among them.

If he had turned his back an instant, or for an instant had ceased to hold their eyes, there would have been another Emperor made on the Wall that hour. Was it not so, Faun?'

'So it was. So it always will be,' said Puck.

'Late in the evening his messenger came for us, and we followed to the Temple of Victory, where he lodged with Rutilia.n.u.s, the General of the Wall. I had hardly seen the General before, but he always gave me leave when I wished to take Heather. He was a great glutton, and kept five Asian cooks, and he came of a family that believed in oracles. We could smell his good dinner when we entered, but the tables were empty. He lay snorting on a couch. Maximus sat apart among long rolls of accounts. Then the doors were shut.

'"These are your men," said Maximus to the General, who propped his eye-corners open with his gouty fingers, and stared at us like a fish.

'"I shall know them again, Caesar," said Rutilia.n.u.s.

'"Very good," said Maximus. "Now hear! You are not to move man or shield on the Wall except as these boys shall tell you. You will do nothing, except eat, without their permission. They are the head and arms. You are the belly!"

'"As Caesar pleases," the old man grunted. "If my pay and profits are not cut, you may make my Ancestors' Oracle my master. Rome has been! Rome has been!" Then he turned on his side to sleep.

'"He has it," said Maximus. "We will get to what _I_ need."

'He unrolled full copies of the number of men and supplies on the Wall-down to the sick that very day in Hunno Hospital. Oh, but I groaned when his pen marked off detachment after detachment of our best-of our least worthless men! He took two towers of our Scythians, two of our North British auxiliaries, two Numidian cohorts, the Dacians all, and half the Belgians. It was like an eagle pecking a carca.s.s.

'"And now, how many catapults have you?" He turned up a new list, but Pertinax laid his open hand there.

'"No, Caesar," said he. "Do not tempt the G.o.ds too far. Take men, or engines, but not both; else we refuse."'

'Engines?' said Una.

'The catapults of the Wall-huge things forty feet high to the head-firing nets of raw stone or forged bolts. Nothing can stand against them. He left us our catapults at last, but he took a Caesar's half of our men without pity. We were a sh.e.l.l when he rolled up the lists!

'"Hail, Caesar! We, about to die, salute you!" said Pertinax, laughing. "If any enemy even leans against the Wall now, it will tumble."

'"Give me the three years Allo spoke of," he answered, "and you shall have twenty thousand men of your own choosing up here. But now it is a gamble-a game played against the G.o.ds, and the stakes are Britain, Gaul, and perhaps, Rome. You play on my side?"

'"We will play, Caesar," I said for I had never met a man like this man.

'"Good. To-morrow," said he, "I proclaim you Captains of the Wall before the troops."

'So we went into the moonlight, where they were cleaning the ground after the Games. We saw great Roma Dea atop of the Wall, the frost on her helmet, and her spear pointed towards the North Star. We saw the twinkle of night-fires all along the guard-towers, and the line of the black catapults growing smaller and smaller in the distance. All these things we knew till we were weary; but that night they seemed very strange to us, because the next day we knew we were to be their masters.

'The men took the news well; but when Maximus went away with half our strength, and we had to spread ourselves into the emptied towers, and the townspeople complained that trade would be ruined, and the Autumn gales blew-it was dark days for us two. Here Pertinax was more than my right hand. Being born and bred among the great country-houses in Gaul, he knew the proper words to address to all-from Roman-born Centurions to those dogs of the Third-the Libyans. And he spoke to each as though that man were as high-minded as himself. Now _I_ saw so strongly what things were needed to be done, that I forgot things are only accomplished by means of men. That was a mistake.

'I feared nothing from the Picts, at least for that year, but Allo warned me that the Winged Hats would soon come in from the sea at each end of the Wall to prove to the Picts how weak we were. So I made ready in haste, and none too soon. I shifted our best men to the ends of the Wall, and set up screened catapults by the beach. The Winged Hats would drive in before the snow-squalls-ten or twenty boats at a time-on Segedunum or Ituna, according as the wind blew.

'Now a ship coming in to land men must furl her sail. If you wait till you see her men gather up the sail's foot, your catapults can jerk a net of loose stones (bolts only cut through the cloth) into the bag of it. Then she turns over, and the sea makes everything clean again. A few men may come ash.o.r.e, but very few.... It was not hard work, except the waiting on the beach in blowing sand and snow. And that was how we dealt with the Winged Hats that winter.

'Early in the Spring, when the East winds blow like skinning-knives, they gathered again off the East end with many ships. Allo told me they would never rest till they had taken a tower in open fight. Certainly they fought in the open. We dealt with them thoroughly through a long day: and when all was finished, one man dived clear of the wreckage of his ship, and swam towards sh.o.r.e. I waited, and a wave tumbled him at my feet.

'As I stooped, I saw he wore such a medal as I wear.' Parnesius raised his hand to his neck. 'Therefore, when he could speak, I addressed him a certain Question which can only be answered in a certain manner. He answered with the necessary Word-the Word that belongs to the Degree of Gryphons in the science of Mithras my G.o.d. I put my shield over him till he could stand up. You see I am not short, but he was a head taller than I. He said: "What now?" I said: "At your pleasure, my brother, to stay or go."

'He looked out across the surf. There remained one ship unhurt, beyond range of our catapults. I checked the catapults and he waved her in. She came as a hound comes to a master. When she was yet a hundred paces from the beach, he flung back his hair, and swam out. They hauled him in, and went away. I knew that those who worship Mithras are many and of all races, so I did not think much more upon the matter.

'A month later I saw Allo with his horses-by the Temple of Pan, O Faun!-and he gave me a great necklace of gold studded with coral.

'At first I thought it was a bribe from some tradesman in the town-meant for old Rutilia.n.u.s. "Nay," said Allo. "This is a gift from Amal, that Winged Hat whom you saved on the beach. He says you are a Man."

'"He is a Man, too. Tell him I can wear his gift," I answered.

'"Oh, Amal is a young fool; but, speaking as sensible men, your Emperor is doing such great things in Gaul that the Winged Hats are anxious to be his friends, or, better still, the friends of his servants. They think you and Pertinax could lead them to victories." Allo looked at me like a one-eyed raven.

'"Allo," I said, "you are the corn between the two millstones. Be content if they grind evenly, and don't thrust your hand between them."

'"I?" said Allo. "I hate Rome and the Winged Hats equally; but if the Winged Hats thought that some day you and Pertinax might join them against Maximus, they would leave you in peace while you considered. Time is what we need-you and I and Maximus. Let me carry a pleasant message back to the Winged Hats-something for them to make a council over. We barbarians are all alike. We sit up half the night to discuss anything a Roman says. Eh?"

'"We have no men. We must fight with words," said Pertinax. "Leave it to Allo and me."

'So Allo carried word back to the Winged Hats that we would not fight them if they did not fight us; and they (I think they were a little tired of losing men in the sea) agreed to a sort of truce. I believe Allo, who being a horse-dealer loved lies, also told them we might some day rise against Maximus as Maximus had risen against Rome.

'Indeed, they permitted the corn-ships which I sent to the Picts to pa.s.s North that season without harm. Therefore the Picts were well fed that winter, and since they were in some sort my children, I was glad of it. We had only two thousand men on the Wall, and I wrote many times to Maximus and begged-prayed-him to send me only one cohort of my old North British troops. He could not spare them. He needed them to win more victories in Gaul.

'Then came news that he had defeated and slain the Emperor Gratian, and thinking he must now be secure, I wrote again for men. He answered: "You will learn that I have at last settled accounts with the pup Gratian.

There was no need that he should have died, but he became confused and lost his head, which is a bad thing to befall any Emperor. Tell your Father I am content to drive two mules only; for unless my old General's son thinks himself destined to destroy me, I shall rest Emperor of Gaul and Britain, and then you, my two children, will presently get all the men you need. Just now I can spare none."'

'What did he mean by his General's son?' said Dan.

'He meant Theodosius Emperor of Rome, who was the son of Theodosius the General under whom Maximus had fought in the old Pict War. The two men never loved each other, and when Gratian made the younger Theodosius Emperor of the East (at least, so I've heard), Maximus carried on the war to the second generation. It was his fate, and it was his fall. But Theodosius the Emperor is a good man. As I know.' Parnesius was silent for a moment and then continued.

'I wrote back to Maximus that, though we had peace on the Wall, I should be happier with a few more men and some new catapults. He answered: "You must live a little longer under the shadow of my victories, till I can see what young Theodosius intends. He may welcome me as a brother-Emperor, or he may be preparing an army. In either case I cannot spare men just now."'

'But he was always saying that,' cried Una.

'It was true. He did not make excuses; but thanks, as he said, to the news of his victories, we had no trouble on the Wall for a long, long time. The Picts grew fat as their own sheep among the heather, and as many of my men as lived were well exercised in their weapons. Yes, the Wall looked strong. For myself, I knew how weak we were. I knew that if even a false rumour of any defeat to Maximus broke loose among the Winged Hats, they might come down in earnest, and then-the Wall must go! For the Picts I never cared, but in those years I learned something of the strength of the Winged Hats. They increased their strength every day, but I could not increase my men. Maximus had emptied Britain behind us, and I felt myself to be a man with a rotten stick standing before a broken fence to turn bulls.

'Thus, my friends, we lived on the Wall, waiting-waiting-waiting for the men that Maximus never sent!

'Presently he wrote that he was preparing an army against Theodosius. He wrote-and Pertinax read it over my shoulder in our quarters: "_Tell your Father that my destiny orders me to drive three mules or be torn in pieces by them. I hope within a year to finish with Theodosius, son of Theodosius, once and for all. Then you shall have Britain to rule, and Pertinax, if he chooses, Gaul. To-day I wish strongly you were with me to beat my Auxiliaries into shape. Do not, I pray you, believe any rumour of my sickness. I have a little evil in my old body which I shall cure by riding swiftly into Rome._"

'Said Pertinax: "It is finished with Maximus! He writes as a man without hope. I, a man without hope, can see this. What does he add at the bottom of the roll? '_Tell __Pertinax I have met his late Uncle, the Duumvir of Divio, and that he accounted to me quite truthfully for all his Mother's monies. I have sent her with a fitting escort, for she is the mother of a hero, to Nicaea, where the climate is warm._'

'"That is proof!" said Pertinax. "Nicaea is not far by sea from Rome. A woman there could take ship and fly to Rome in time of war. Yes, Maximus foresees his death, and is fulfilling his promises one by one. But I am glad my Uncle met him."

'"You think blackly to-day?" I asked.

'"I think truth. The G.o.ds weary of the play we have played against them.

Theodosius will destroy Maximus. It is finished!"

'"Will you write him that?" I said.
