‘Meekal is coming here later today,’ he added. ‘He had a wretched meeting with the Caliph. Khadija has raised most of the Council against him.’ I shrugged. ‘She tells me we need to discuss the demonstration. Do you suppose everything will be ready in time?’ I squirted a fountain of water between pursed lips and followed this with a toothless grin. Karim nodded. ‘It might be useful,’ he said, ‘if not everything worked perfectly on the day.’ I lifted my left foot above the water and let him inspect the nails for more dirt I might have picked up the previous day. ‘What I mean,’ he went on, a slight pleading tone in his voice, ‘is that we don’t want a complete failure – not the sort of thing that will get everything cancelled. What we have in mind is a partial success. We’d like it made plain that the weapon can be made to work, but only after more time, and more money – perhaps quite a lot of money.
‘Can you hold off giving Meekal the final details of how everything works?’ he asked, changing the subject. ‘There will be a full meeting of the Council once everyone is back in the palace. The Lord Treasurer will present a long report. Our friends will make their move in the discussions arising. Once Meekal has been sent off to inspect the garrisons against the Yellow Barbarians, Khadija will have an offer made of private funding to complete the project. We are thinking of another successful demonstration in the early autumn. Can you play along with this?’
‘When Edward becomes one of the Faithful,’ I asked with another of my toothless grins, ‘I suppose he will pass under your complete protection? And that will mean the full protection of Khadija and all her friends?’
Karim nodded, giving me something from his people’s Holy Book about the Brotherhood of the Faith.
‘Then it will all be as you ask,’ I said. ‘I am curious, though, why Khadija is so confident that she can finally get Meekal put out of the way. Are finances really as tight as you indicate? Does this mean the civil war is going worse than the palace heralds keep saying? Have there been more reverses in the war with the Empire?’
‘You’ll need to speak with Khadija about that,’ came the evasive reply. I lifted my arms in front of me and sank under the water. I felt Karim’s hands close on my shoulders and pull me back up. I rubbed water from my eyes and smiled into his scared face. ‘Don’t do that again – please,’ he begged. He looked at the wet sleeves now clinging to his forearms.
‘What you’re asking me,’ I said, ‘involves risks in which none of you people will share. If I don’t give Meekal the show he’s expecting, it may be enough to discredit him. On the other hand, he may tough out the Council meeting. If he does that, he’ll not be pleased with me or mine. Can you oblige me with the names of Khadija’s friends in the Council? I need to be sure this is a regular conspiracy and not some half-baked palace intrigue got up by women and eunuchs.’ I looked closely into the now plainly terrified face. ‘I want the full names and offices of the conspirators. And don’t trouble me with making up the details. Over the past three generations, I’ve developed a crap-detection sense that many judges might envy.’ I gripped the sides of the bath and kicked my feet up and down. I listened with lazy contentment as water gurgled down the lead overflow pipe.
‘And do open that cold lever a little. I’m beginning to feel as a lobster must.’
Chapter 59
‘You know,’ I said brightly, ‘it looks so much different, even from another fourteen feet higher.’ The foreman muttered something about the breeze and gently led me back from the edge of the roof. The sun was now fully up, and I could feel a trickle of sweat from under my wig. But if it was unlikely to carry me over the edge, the breeze was most welcome. ‘I hadn’t realised that the Spice Market had a double vault to its roof,’ I said. ‘I’ve been looking at it for months. But I suppose fourteen feet does make a difference.’
The foreman sighed and went back to his explanation of the roof – and he was in a position to lecture me on the thing, as he’d helped lay it the previous Ramadan. It was a marvel of two-inch-thick cedar boards, each cut into a gentle fan and laid with barely a gap from the centre of the tower to its outer edge. Over these was a layer of pitch, then of canvas, and then an outer covering of lead.
‘Admirable, most admirable,’ I said. ‘However, even if the boards are supported along their lengths, I do still urge two further layers of ten-foot boards, each at a right angle to the other. That should spread the load without any further worry.’ The foreman bowed and made some marks on his waxed tablet. It would all be as I desired. I looked again at the half ton of brass that sat before me, gleaming in the sun. The young man who’d so far stood silent before me, hands folded across his breast, would soon explain the use of those dials and levers.
I was thinking also of an awning to keep the sun off me. I’d be up here several days running, sometimes through the hottest hours. As I was deciding between silk and linen, the foreman and everyone else threw themselves down for a long grovel.
‘Ah, Meekal,’ I said without turning, ‘I was wondering when you’d put in an appearance.’ Even my defective hearing wasn’t enough to blot out the sound of his breathing: I might have had an angry bull behind me. I turned and made the feeblest pretence of a bow.
‘What is the meaning of this?’ he said with the sort of quiet menace that can swell very fast into hysterical screaming. He waved at the half-dozen large astronomical instruments.
‘I’m a newcomer myself to solar observations,’ I said with a bright smile. ‘Until that young man cowering at your feet enlightens me, it’s all a bit of a mystery. However, I do think that big machine over there with the electrum plates is used for finding the angle of separation between two stars. I’m sure I’ll find it useful for something.’
Meekal put his head down and walked a few paces along the roof.
‘Have you any idea,’ he said, turning back to me, ‘how much these devices cost?’
I held my arms wide out and pulled the appropriate face. ‘It isn’t my concern either,’ I added. ‘The deal is that I ask for whatever I need. The funding is your problem.’
Meekal pushed his face close to mine. ‘The deal is that you complete my project,’ he hissed, now in Latin. ‘From what little sense I’ve had from Karim, these are for your private researches.’
I sat down and stared at Meekal. I picked up a fly whisk and waved it vaguely about my head. Everyone else was still clutching the ground, as still as in death.
‘Then, if you’ll pardon me for saying,’ I sneered, still in Syriac, ‘you’re a right barbarian. We aren’t talking here about a recipe for fish sauce. I need complete freedom to research as I see fit. Do you want the Caliph to stand up and cheer when I set those kettles off? Or do you want to offer him an unusually vigorous steam bath?’
‘I have just finished a meeting with the Caliph,’ came the response in a voice that really did remind me of one of my kettles. ‘He was accosted on his return to the palace by the Director of the observatory you had just plundered. His Majestic Holiness was not pleased.’
I got up and laughed. I walked close to the edge of the roof and rapped hard with my stick on a bronze adjustment bar.
‘So that’s how it is,’ I cried in a loud voice. The breeze had dropped down again, and my voice was flat but clear. I made sure to keep in Syriac. ‘When the Commander of the Faithful is away, you’re top dog. When he’s back, you answer to his finance clerks. And to think you betrayed your family, your country, your religion for this. I could have got you made Exarch of Italy. Why, you’d have had more authority as Prefect of Cartenna!’
Meekal glanced down at the carpet of grovelling bodies. ‘Get off this roof – all of you!’ he snarled softly. He waited until everyone had darted through the hatchway in the centre of the roof that led down to the access ramps. He kicked the hatch closed and came back to me. I was back in my chair, and was pretending to inspect the handle of my fly whisk. He stood over me. His black robes heaved in time with his breathing. ‘If you cannot do so in private, I do sugge
st, for your own good, that you show some respect in public.’
‘Fuck you, Michael!’ I answered in Greek. I looked up at the cloudless sky. My left leg was hurting, and I could feel the need for a piss coming on.
‘Is there one reason,’ he asked slowly and with much effort, ‘why I shouldn’t have these things collected at once and taken back to where they belong?’
As I was wondering how he’d react to my standing up and pissing close to his feet, I heard the first scrape of the water screw. It was over on the far side of the tower. But, without the insulation of walls and glazed windows, the laboured, squealing, grating sound was unpleasant on the ear. I clutched hold of a brass lever and pulled myself up. I held out my arm for Meekal to take. Together, we made our way across the roof to where the covered water tank was placed. For the moment, the noise came from below, as water was pushed up the rotating lower screw to the tank within the tower. Then, with a more continuous and still louder screech of bronze pipe within bronze hoops, the upper screw began to rotate. At first, it was just a shuddering movement of weather-corroded metal. Then, with a loud splutter, the first bright splash of water jumped on to the collection pan and was channelled into the lead tank. It was like watching a giant, if sluggish, ejaculation as the tank was slowly filled. Far below – perhaps right on the ground, perhaps within the tower itself – there came the higher sound of a whip and a suppressed cry. Someone laughed unpleasantly, and there was another crack of the whip.
‘You know,’ I said, speaking as best I could above the noise, ‘I’ve been wondering ever since I came here if some arrangement of gears wouldn’t cut out the need for a break into the pipe.’ I waited for the puzzled look on Meekal’s face to pass. I waited in vain. I shrugged and let him help me on to the low stool he’d carried across with us. Water was now running back down the pipe, and this was lubricating its movement within the hoops. The noise had changed to a dull, continuous grating of metal on metal. ‘It’s about seventy feet from here to the ground. There’s no reason why a single pipe of that length can’t be made. Each of the two existing lengths was cast in sections, then welded together. The two sections themselves could easily be joined. The limitation is that the highest rotation speed isn’t enough to push water the whole distance. That’s why the engineers broke the course with a supplemental tank. But if the rotation speed could be increased without limit, there might be no limit to how far water could be raised. That’s why I thought of gears.
‘Since yesterday, though, I’ve been thinking further. I used steam in our demonstration as a substitute for the real thing. But suppose you could match a steam kettle to the sort of wheel you see on a water mill. That, plus the gears, would give enormous force to any rotation. You’d be turning heat into motion. Has it ever struck you that all human might so far has been based on the power of human or animal muscles?’ I ignored the lack of response. I was speaking now more for myself than for Meekal. If he’d gone and thrown himself off the roof, I might have got up for a dance of joy. Or I might have carried on with the lecture.
‘Even when there is no limit to the quantity of muscle power, there are limits to its effective use. Yet heat can be generated wherever there are adequate supplies of fuel, and can be converted into both intense and rapid motion. Give me funding and a team of engineers and metal workers, and I’ll give you a machine that will raise water seventy feet – and have it spurting ten feet beyond that. Indeed, once the basic point is realised, of the conversion of heat to motion, I can imagine ships that sail regardless of winds and tide, and vehicles that can travel on the roads day after day at the speed of a galloping horse.’
‘You’ve been at that shitty opium again,’ Meekal sneered.
I smiled and sat up. I took off my visor and waved it at him. ‘Bearing in mind what I have already achieved,’ I asked, ‘must I make out the same case, in each and every other instance, for the benefits of understanding and controlling the world about us? Can you not at least see that the first civilisation to bow before the power of natural reason will conquer the world? Is not the weapon I am about to give you a feeble thing compared with what might one day be? Are not your own victories in the East as much an effect of chain mail and swords as of religious enthusiasm?’
Meekal gave one of his contemptuous laughs. He held out a hand to take my arm and led me over to the exit hatch from the roof. I stopped by one of the larger instruments. Its calibration marks told me it was of Alexandrian workmanship – possibly from before the Roman conquest of Egypt. For something of its age, it was in good shape. A pity, though, that seven hundred years hadn’t rendered it as obsolete as the numerals that had to be learned before it could be made to work. I pulled free of Meekal’s grip and carefully sat myself on the warmed lead within the shadow of the instrument.
‘Do you remember that story told of Tiberius – the Emperor who succeeded Augustus in ancient times, not the one a hundred years back who came before the unfortunate Maurice?’ Still nothing from Meekal. I got slowly up and looked over the rooftops of Damascus. The breeze was coming up again. ‘He was approached one day by a craftsman who said he’d made a new sort of glass cup. As the Emperor reached out to take the cup, the craftsman let it fall from his grasp. Tiberius stood back to avoid the smashing of glass on the floor of his palace. Instead of shattering, though, the cup bounced on the marble. The craftsman took it up and produced a little hammer, so he could knock out the slight dent of the impact. Impressed, Tiberius asked if anyone else knew how to make such glass. “No,” came the answer. It was a secret known only to one man. Was he rewarded with a kiss of joy and a soft loan to build a bigger workshop? No, he had his head cut off. Let the secret of unbreakable glass be common knowledge, said Caesar, and no one would ever commission cups of gold and silver. After a while, no one would even buy new glass cups. The death of one man, he said, was essential, if thousands were not to lose their livelihoods.
‘If you want to see the effects of that mode of reasoning, go and look at the heap of stinking ruins that Rome has since become. There is no limit to the work that can be done and needs to be done by human labour. Improvements that increase the force of human labour simply increase the wealth and power of the human race.’
Still no words from Meekal. But I could now see the look of pained resignation on his face. ‘So I get to keep this lot for the next month,’ I said rather than asked. Still no answer. ‘Do be kind enough, then,’ I said with bright cheer, ‘to remind that foreman when you let him back up here, that this roof has a slight pitch, and that levelling wedges need to be placed under the planks.’ This time, he nodded.
‘Oh,’ I added, ‘if you want everything ready on time, I’ll need to spend several days at the old Saint Theodore Monastery. I’ll need to go into every one of the restricted zones, and pass and repass between them. This isn’t negotiable. I need more than one day to get everything ready. So you can either drag yourself out of Damascus with me, or dispense me from some of your security rules.’ I got a cold look for that. I ignored it. ‘And you can replace those mangy guards you’ve been using for my protection. Now the Caliph is back, I want a brigade of proper fighting men about me every time I set foot outside the palace.’
Another cold look. But Meekal was walking towards the hatch. You may think I’d pushed my luck quite far enough. But I could feel the jolly tiredness of an early siesta coming on. I rapped the lead covering of the roof with my walking stick.
‘And since you’re going that way,’ I croaked, ‘do have some beer sent up for me. Yes – beer and a piss pot. It wouldn’t do for me to piss over the edge of the roof. You never know at the moment who might be passing by underneath.’
Chapter 60
Because it kept me in the palace at a time when I had work to do elsewhere, the banquet was as much a nuisance to a busy man as a burden on an old man. But if I’d twisted like an eel to get out of it, Meekal had held me firm. And so, dressed in heavy finery, my head freshly shaven and bewigged, I was led to
my dining couch as if to some place of execution.
The banquet was in the same place as before. There was scorching to some of the columns that hadn’t come off with scrubbing, and there was a small army camped all around the hall. This time, of course, there was no attack to cut short the proceedings. This time, also, I wasn’t anything like guest of honour. My own dining couch was at the far end of the hall, and my only dealings with Meekal were a whispered lecture as he came to stand beside me on the use of gold in the transmutation of materials. I gathered that His Majestic Holiness would spend the following day on an auditing of the research budget, and there was some opposition within his Council to the extravagance of the demands I’d made. But this was a brief lecture. How much of it Meekal really took in wasn’t my concern. He’d probably parrot the relevant points well enough. Besides, it had all been agreed long in advance that the Council wasn’t to be told enough to compromise the security of the project.
‘I’ll join you out in the desert before you arrive at the monastery,’ he’d said with one of his unpleasant glares. I had supposed Meekal would be stuck all day with the auditing. But, if I’d caused him further trouble with my demand for the additional gold bars, even that wouldn’t keep him stuck all day in the Council. The several days of freedom I’d pulled out of him, to potter about in the monastery to my heart’s content, would now be brought to an end. ‘Then it must be Karim who has responsibility for my safety on the desert journey,’ I’d replied. ‘The additional men seem to have scared off the Angels of the Lord. Just make sure to send out someone with Karim who knows how to direct a fight if one is needed.’
