'Ibn Sharaf argues that a comet isn't a cloud, or a kind of star, as has been supposed by some. Some astronomers have seen the comets slide across the sky, brightening and darkening as they go. Ibn Sharaf says that comets ride on invisible roads between the spheres of heaven, brightening as they near the glow of the sun, diminishing as they recede. Ibn Sharaf is trying to establish the shape of such paths, for if one had that then perhaps one could explain the comets' strange periodicities. And perhaps one could know when to expect the next visitation.'
'As,' Godgifu said slowly, 'the drafter of the Menologium seems to have known.'
'To the men of the future,' Sihtric said pompously, 'the path of a comet in the sky will be a trivial puzzle.'
This irritated Orm. 'Well,' he said, 'even if that's so, they've got it wrong this time, haven't they? For March is nearly over, and your prophesied comet hasn't appeared yet.'
'It will come,' Sihtric promised. 'Ibn Sharaf and his astronomers are watching under the clear skies of al-Andalus.' But, a small man full of nervous tension, he was unable to sound confident.

That year, Easter fell in the middle of April.
Harold, with his pregnant bride, returned to Lunden, and held his Easter court at Westmynster. He took this first opportunity to display his power and status. There was a cycle of feasting, worship, receptions, and meetings to deal with royal business. He welcomed bishops, earls and thegns, and embassies from Scotland, Wales, Ireland, and the continent.
Sihtric and Godgifu took lodging in a house close to Westmynster that had belonged to a thegn of Tostig.
It was an uneasy time for Sihtric, for even now his overdue comet did not appear. Restless, agitated, he decided to deal with his 'rival' prophet, the monk Aethelmaer. Leaning on the authority of the bishops at the court, he summoned Aethelmaer from his monastery in Wessex.
Aethelmaer, crippled, had to be carted across the country on the back of a wagon, and then in Lunden two hefty young monks carried him everywhere on a litter.
On his arrival, Sihtric, Godgifu and Orm were shown into Aethelmaer's presence in Westmynster abbey. He was a fat man of about fifty lying stiffly on a couch, animated only from the waist up, his useless legs withered. There was a stink of rot in the room, only partially masked by wood smoke and a sharper tang of unguents.
At Aethelmaer's side was a low table covered in manuscripts and notes. Sihtric said, 'Despite your handicap, you have remained busy. God would be pleased.'
Aethelmaer, evidently an earthy man, snorted at that. 'But it was God who put me in my litter in the first place – God, and a handful of feathers, and the hardness of the earth… These sketches are just that, you know, scribbles on paper. It is only when you realise the machines, with wood and rope, canvas and cloth, metal and feathers, that you start to see what works and what doesn't – and how much you don't understand. And if God had chosen to leave me my legs I could have got a lot further by now. Eh, eh?'
'Machines?' That sparked Orm's curiosity, and he walked over to see the sketches for himself. Filled with complex diagrams they were grimy with handling and covered by spidery notes.
Sihtric said, 'Word of your prophecies have reached the court. They say that you have forecast the coming of a comet.'
'A comet? Oh, yes.' Aethelmaer reached painfully to tap the heap of papers. 'It's all in here. The comet will come, and England will fall – but it will rise again, changed.' He slumped back, face twisted with pain. 'But it's not the comet that matters, you know. It's all this.'
Orm said, 'These look like machines of war. Are they siege engines?'
'Oh, more than that,' Aethelmaer said, and he grinned to reveal rotting teeth. 'Have you ever seen a siege engine that could swim under the sea? Have you ever seen an engine with wings – an engine that could fly? The Engines of God, we call them.'
Orm stared, shocked.
A young monk came in, an attendant from Maeldubesburg, carrying a tub of water and a cloth. 'Time for your wash, Domnus.'
Aethelmaer grumbled, 'Can't you see I'm busy?'
The monk wouldn't be put off. 'You're always busy. Come now.'
Aethelmaer acquiesced as the monk lifted his habit. His legs were white as snow, and one shin was afflicted by an ulcer, a suppurating, bloody, pus-soaked sore with the gleam of exposed bone. The stench of rotting flesh filled the room. Sihtric gulped, and Godgifu turned away. But Orm, a veteran of battlefields, had seen worse.
Sihtric said, 'Tell me where this prophecy came from.'
Aethelmaer seemed to feel nothing at all as the monk swabbed out pus and cut back rotten flesh. 'You're aware that our comet is a repeat visitant.'
'That's trivial,' snapped Sihtric.
'Then let me tell you that my "prophecy", as you call it, was a product of the comet's last visit to the earth.'
Sihtric, not to be outdone, hastily checked his own figures. 'In the year of Our Lord 989.'
'Exactly! And in that year, as the comet shone, a child was dumped at the gate of our monastery in Maeldubesburg: naked, no more than a few days old…'
The monks had taken in the child, as was their custom, and found him a wet-nurse. As a private joke they called him Aethelred, after the then King.
It soon became apparent why the baby had been abandoned. As he grew he was a pretty boy, but quick to walk and slow to talk. He would spend hours on his own sketching figures in the dirt, but if put with the other children in the monastery school he would fight and scratch. 'He was a damaged child,' Aethelmaer said, 'with something broken inside – broken or never formed.'
Nobody knew what to do with him until one inspired brother, seeing him scratching in the dirt, handed him a bit of chalk. At first his obsession with drawing was merely a way to keep Aethelred occupied – but it soon became clear that his drawings were more than just scribbles.
Sihtric guessed, 'You mean these designs.'
'Yes! You can see how detailed they are – look, it's as if you can see inside the bodies of the engines. But there is no explanation, no lettering – save for blocks, like this one, of cryptic symbols, which nobody has been able yet to decode.'
Orm gazed at one such block, which was unhelpfully labelled 'Incendium Dei': BMQVK XESEF EBZKM BMHSM BGNSD DYEED OSMEM HPTVZ HESZS ZHVH
It meant nothing to him.
There was, though, one picture which showed one star looping on an egg-shaped course around another. This was the diagram which Aethelmaer had unpicked to establish that the comet that had marked Aethelred's birth was destined to return in the year 1066.
Sihtric asked, 'And who taught the boy to draw these designs?'
'Nobody,' breathed Aethelmaer, and his eyes gleamed, for this was evidently the mystery that informed his whole life. 'Nobody. He was drawing such designs from the age of four, almost as well-executed as these from the very beginning, his limits only his childish hand, his inexperience with the pen. Somehow all this was poured into his head.'
'From where? How?'
Aethelmaer shrugged, and winced with pain. 'How can I know? From God, perhaps.'
Godgifu murmured to Sihtric, 'That sounds like the origin of the Menologium of Isolde.'
'Yes. Then perhaps this prophecy, if that is what it is, and the Menologium, have a common source.'
Aethelmaer said, 'You understand this was all before my time. I was born in the year Cnut came to the throne – long after poor Aethelred had gone back to his Maker. But as a young deacon I showed aptitude for study, and the abbot set me to working on the papers Aethelred had left behind.'
