‘Two?’ Claudia lifted her head, shading her eyes against the sun. She recognised the slave as the same one she’d questioned near the ruined House of Mourning.

‘You wish to drink with me?’

The man’s tired face broke into a smile.

‘I would dearly love so, mistress. I apologise for my impudence, but you have a kind face and a generous heart.’

‘Who are you?’

‘My name is Narcissus. I am, by nation, a Syrian.’ Without being invited, he sat down next to Claudia. ‘I was by profession an embalmer. I looked after the dead until I was swept up in a stupid revolt just outside Damascus.’

Claudia pushed the wine cup into his hands.

‘You know how it is,’ Narcissus continued woefully. ‘Some idiot begins a fight. The innocent are drawn in, the legions arrive, the leaders are crucified and the rest are sold to slavery, end of story.’ His face grew even more lugubrious. ‘I used to be known as Narcissus the Neat, I was so skilled in my trade! I was especially proud of my precision in preparing a corpse. I always broke the nose bone with the greatest of ease and drew the brains out without creating too much mess.’

‘Yes, yes,’ Claudia interrupted, staring at the food. ‘But how did you become involved in the revolt?’

Narcissus drained his goblet, and Claudia emptied hers into his. The slave relaxed sipping at the second goblet of wine, staring at Claudia like a hungry puppy.

‘To answer your question, mistress, I lived five miles outside of Damascus. This madman appeared, calling himself Simon the Saviour, a great sombre-faced brute. He had been to Egypt and learnt a few tricks. He promised that those who believed in him would live for ever beyond the Far Horizon; they would die but, if they were followers of the god Osiris and were buried according to the sacred rite, they would not only live for ever but would be able to come back and assume different forms.’

‘Surely you didn’t believe that nonsense?’

‘No, I didn’t. But my wife did, though that was because she was sleeping with Simon, our so-called Saviour.’

Narcissus paused, watching a crowd of courtiers cluster in the colonnade. They had surrounded Athanasius, congratulating him in their high-pitched voices.

‘I had no choice,’ Narcissus continued. ‘Some people answer to God; I answered to a higher authority, my wife. Anyway,’ he blew his cheeks out, ‘Simon said he needed me because I was an embalmer. The stupid fanatic seized a fort on the edge of the desert and proclaimed that the Day of the Far Horizon had arrived. We raised the standard of Osiris and defied the local governor. He sent troops, a tribune with a force of foot and cavalry. My wife was killed, Simon the Saviour impaled.’ Narcissus sniffed. ‘That gave me some satisfaction, even though I ended up on the slave block.’ He looked at the platter of food and swallowed hard. Claudia heard his stomach grumble.

‘Eat,’ she ordered, handing it over, ‘and I mean eat. You are my guest, Narcissus, I’ll take responsibility.’

The slave needed no second bidding and attacked the food like a ravenous wolf. Claudia got to her feet, went over to a side table laid out in the shade and brought back another jug of wine. Narcissus was busy stuffing food into his mouth. Claudia felt a deep compassion for this middle-aged man, who was so hungry he had forgotten his status in order to fill his belly. Some of the courtiers were looking at her strangely; a pompous chamberlain, a eunuch, came waddling over. Claudia told him to stay well away.

‘If you wanted food,’ Claudia whispered, ‘you should have asked, but there again,’ she patted his shoulder, ‘I should have noticed.’

‘I wasn’t just hungry,’ he replied between mouthfuls. ‘I wanted to tell you about the fires.’

‘Yes, I know, the House of Mourning was burnt.’

‘No, the fires,’ he repeated. ‘I have to tell someone what I saw. Last night, as I’ve said, I ate well and drank deep, on not very good ale. I became truly drunk and fell asleep just behind the latrines. I was roused by the clamour caused by the House of Mourning burning. I jumped up and ran round; the flames had caught hold. Gods, I thought, they’ll blame me! I’ll be for the stake or the cross, so I fled. I jumped the wall and ran to the top of the hill. This villa is built on the side where the ground has been levelled off. Anyways,’ Narcissus wiped his mouth on the back of his hand, ‘there I sat, staring at the stars above me, wondering what I should do. If I ran away they’d certainly blame me. Indeed, I had nothing to fear by staying. I had witnesses to say where I was, and the House of Mourning was left safe. There was no lamp there, no oil, nothing which could cause such a blaze. I’d done nothing wrong. I’d-’

‘And?’ Claudia interrupted.

‘I calmed down. I stared up at the stars, the air was cool and sweet. I closed my eyes. I swear I could smell the jonquil which grew so rich and profuse in the valley where I played when I was a boy. Anyway,’ Narcissus hurried on, ‘I opened my eyes. From where I sat, I could still see the House of Mourning, but, staring out over the countryside, I glimpsed other fires.’

‘What?’ Claudia exclaimed.

‘Other fires, mistress. They weren’t blazing when I first arrived, I’m sure of that. But staring into the darkness, I could see one in the middle distance, then another a little further on. At the time I didn’t think anything about it. I thought they were harvest fires, but there’s been no harvest yet. Such blazes aren’t lit for at least another two months. Then I thought about Simon the Saviour.’

‘What about him?’ Claudia tried to curb her exasperation.

‘That was what he did when the revolt started. He lit beacon fires, piles of brushwood oiled and flamed. He called them the Lights of Heaven, much good it did him.’

Claudia stared around the exquisite, sophisticated garden. The peristyle was now filling up as more courtiers and officials wandered down to eat from the banqueting tables and take their rest in the coolness and fragrance of this lovely garden. She felt a shiver of fear. Something about Narcissus’s account stirred her own memories of the previous evening. She recalled walking over to that sycamore tree where the imperial family were sitting. That was it! The night breeze had been blowing against her, in the direction of the burning House of Mourning, yet she still smelt wood smoke. What if Narcissus was correct? Was the House of Mourning a beacon light? A signal to someone outside which was then sent on? During her travels up and down Italy, as a member of the acting troupe, Claudia had seen the marching armies and heard the clash of battle. She recalled the dark hills further north, the beacon fires burning in the dead of night as the armies of Rome manoeuvred to face each other in bloody confrontation.

‘Tell me,’ she asked, ‘did you look the other way?’

‘What do you mean?’

‘You were sitting on the hill staring down at the villa, yes? That lies to the south. Were there fires to the east and west, or behind you to the north? I’m giving rough calculations,’ she added. ‘Were the fires you saw in a direct line beneath you or all around you?’

‘No, all before me, I could see nothing to the right or left. By the way, I’ve worked here for five years, I know my directions.’

Claudia’s unease deepened. Narcissus was correct. Why were such fires blazing at the height of summer? According to him they were not brushwood or forest fires caused by the heat, but deliberately lit. If they were beacon fires, what was it all about? She racked her brains; there were no great feasts or celebrations. Should she tell the Augusta? Yet what if she was wrong? Claudia stood up.

‘You’re coming with me.’

‘Where to? What for?’

‘For a summer’s day’s ride. Go down to the stables and ask the grooms, on the authority of Claudia, messenger of the Augusta, to prepare my horse — it’s a gentle cob — and a mount for you.’
