Ballista joined him. Figures were appearing from the front of the temple. They were brandishing makeshift weapons – scythes, flails; a few had swords. They were rushing around the corner of the podium, heading towards the fire. Ballista looked questioningly at the man next to him. ‘The stupid fuckers think to save the temple of Artemis,’ the man said.

For a moment Ballista was dumbfounded. ‘But the Goths will massacre them.’

‘Yes,’ said the man.

‘Heracles’ hairy arse,’ said Maximus. ‘You cannot save people from their own stupidity.’

‘No,’ agreed Ballista, ‘but we will have to try.’ Calling for Maximus, Hippothous and the four soldiers to follow, Ballista set off back down the stairs.

At the foot of the steps, Ballista turned towards the entrance. He slid to his arse, propelled himself down and through the great window, and ran through the avenue of columns.

A crowd jostled in his way. He shouted for them to move. They took no notice. He drew his sword and swung it. The flat of the heavy spatha hit a man on the side of the head. He fell. Ballista swung the sword again. A man struck on the shoulder reeled away. The crowd parted.

Reaching the entrance, Ballista turned. His men crushed in behind him. Ballista flashed the blade in a fast, complicated pattern. Its edge shone, evil in the light. The crowd drew back.

‘No one leaves the temple. All of you, go back to the adyton.’

Their courage deflated, the mob melted away.

‘What about the ones outside?’ Maximus asked.

‘They are fucked,’ said Ballista.

It took nearly two hours for the Goths to plunder their way to the temple of Apollo. Enough time for Ballista to improvise some sort of defence. A shieldwall of eight in the gap between the columns: Ballista himself, Maximus and six soldiers. Eight close-lapped shields, two levels of four, protecting them from missiles. One soldier up on each side of the roof, trying to ready the locals to hurl things down on to the attackers. Hippothous also on the roof, tasked with going wherever he might be needed.

Ballista studied what was in front of him. Fourteen steep steps. Beyond, a flat area of beaten earth across the front of the temple, maybe twenty paces deep. Just in front and to the right of the foot of the steps, a big cone of solidified ash held by a low circular wall: the main altar. There were other altars, statues and inscriptions dotted here and there, but not enough to give the Goths much cover. They would have to cross the open ground and then attempt the steps.

The waiting before combat was always hard. The soldiers were silent, their kit creaking as they shifted their weight. Maximus whistled tunelessly, then launched into a lengthy monologue about a girl he had had in Miletus. His tone was one of mock outrage that a girl would initiate such depravity, and him an innocent boy from a distant island. It was a good job he was broadminded and had excellent stamina.

Smoke swirled around the monuments of Hellenic piety. There was a lurid yellow quality to the light, a reek of destruction. Not far away, people were screaming. Maximus kept talking.

The first Goths materialized through the smog of their own making. Helmeted, bearded, they slowly coagulated into groups.

‘Come on, you little piggies,’ called Maximus in the language of the raiders. ‘Come and get skewered.’

Ballista reflected that the obscenity did not translate well from the Greek. As far as he was aware, in the Gothic dialect of the language of Germania, ‘piggy’ was not a synonym for ‘cunt’.

A solid shieldburg of warriors had formed facing the temple. A warrior took a couple of paces forward. He kept himself well covered by his shield.

‘I am Respa, son of Gunteric, of the Tervingi. The murdered Tharuaro was my brother. You in the temple, give up the oath-breaker Dernhelm, son of Isangrim, the skalks the Romans call Ballista, and you have my word you will be spared.’

Ballista laughed. Gunteric could call him oath-breaker, slave, anything he wanted. With the exception of Ballista himself and Maximus, it was most unlikely anyone in the temple understood any of it, apart from his Roman name.

A voice called in Greek from the midst of the northmen, slightly muffled but audible. Presumably it was Chrysogonus. When Respa’s words had been translated, there was murmuring in the dark corners of the temple. It was cunning, but Ballista was not unduly worried. Even should they desire it, these Milesian civilians did not have the balls to try and give him up.

‘I know you,’ shouted Maximus. ‘Respa, the one they call Cocksucker. You must miss your brother’s sword in your mouth.’

‘And I know you, the foul-mouthed Hibernian catamite of Dernhelm.’ The big Goth raised his sword hilt-up to the sky. ‘Fairguneis the Thunderer, all you high gods of the Goths, I pledge two fine stallions and a dozen oxen, if you grant Dernhelm Oath-breaker and the foul Hibernian fall beneath my sword.’

Ballista snorted derisively. ‘You are long on words, but short on courage. Here we are – come and try your luck.’

Respa did not reply. At his gesture, a dozen or so warriors shook themselves out of the shieldburg. Big men, in helmets, shields, mail coats, swords, all sporting a surfeit of golden arm-rings. Men to be considered. Their reiks led them warily forward.

They halted, spread out by the circular altar. Respa spoke to them, too low for Ballista to hear. A single tile dropped from the roof. It shattered harmlessly. The Goths laughed, an unpleasant, wolfish sound.

Ballista silently cursed the Milesians on the roof. How much nerve did it take to throw things from a position of complete safety? What the fuck was the soldier up there doing? Where was that posturing Greek Hippothous? The Goths should be advancing through a hail of missiles.

Respa and another warrior took the lead. They reached the first step. The others fanned out behind.

‘Open order,’ Ballista shouted. Everyone apart from Ballista and Maximus fell back. The two of them shuffled into position, alert to the need for room for their swordplay.

Respa and the other champion came up the steps.

‘Now!’ said Ballista. As one, Ballista and Maximus took three paces back. Only a fool would make a stand at the top of a flight of stairs – your legs were exposed; it was further for your sword to stretch down. They both dropped into the ‘plough guard’: shield out, its leading edge pointing at the enemy, sword held underhand, low to the side.

Respa bounded over the top step. With horrible speed, he took two quick paces, unleashed a deafening war cry and a vicious diagonal cut down to the neck. Ballista raised his shield. Respa fluidly lowered his stroke. Ballista got his shield down just in time to prevent his left ankle being severed. Even as the wood splintered and the impact ran up to his left shoulder, Ballista struck overhand, a short-edge thrust to the face. Respa caught it on the rim of his shield, forcing Ballista’s sword arm up and wide. Like a steel serpent seeking hot blood, the Goth’s blade flickered across at Ballista’s exposed right arm. A lifetime of training saved Ballista. Without conscious thought, he brought his shield up, round and forward, crunching into Respa, trapping the reiks ’s blade between the linden boards and his own chest. For an instant their faces were together, their breath mingling. Ballista ducked, heaved; his knees bent, he shoved the Goth backwards. Panting, a little apart, both gathered themselves. The whole exchange had taken no more than two seconds.

The Goth who had gone for Maximus was down, moaning in pain. His companions grabbed his feet, dragged him clear. He left a bright smear of blood on the marble flagstone. Another took his place.

‘Give my regards to your brother,’ goaded Ballista.

Bellowing incoherently, Respa hurled himself forward, swinging a mighty overhand cut. Ballista did not flinch. Somehow he kept his nerve. Eyes on the sword, the heavy steel slicing down towards the top of his skull. At the last instant, Ballista stepped to his left, bringing his shield up and across. The metal shieldboss buckled with the blow. It almost forced Ballista to his knees. But he twisted, got his shoulder behind his shield, his whole body weight. Twisting and pushing, he drove his assailant’s sword off to the right, exposing the Goth’s unguarded side. There was nothing for Respa to do now but die.

With all his strength, Ballista thrust, low and underhand. There was momentary resistance, then the sharp cracks as metal rings snapped, and the wicked tip of the blade was sliding through soft tissue.

Respa screamed. His spatha rang on the stones. Ballista turned the blade, once, twice. The blood splashed hot on his arm. Locked in a ghastly, intimate embrace, Ballista glanced over the shoulder of the dying man. None of the Goths had a clear strike. Bracing with his shield, Ballista withdrew his blade, and pushed Respa away.

The big reiks tottered back. He dropped his shield. His hands went to the rent in his mail shirt; a futile attempt to staunch the blood. The gore pulsed down the Goth’s legs, puddled by his boots.

A frozen moment, and then Respa fell backwards down the steps. The man behind tried to catch him. He was knocked down. A third Goth was swept down in the tangle.

The warrior facing Maximus was stepping back. His shield was hacked, his face horror struck.

Now the men on the roof were doing their duty. Tiles, stones, scraps of metal were raining down on the steps. Sharp shards and splinters sang through the air. The Goths had their shields up, trying to cover their fallen leader, themselves. They began to pull back, dragging their dead and injured.
