3 THE INFERNAL DEVICE
The stranger halted and fixed Leonardo with a hostile stare. The man’s sallow face was all sharp angles with heavy brows and a slash of a mouth – as if it had been carved from flint by an impatient sculptor and left unfinished.
Leonardo felt himself being probed by the cold, grey eyes. He had the awful feeling that if the man suspected he had been listening at the door, his life would not be worth a single denaro.
The stranger’s gaze moved down over Leonardo’s garb, his expensive tunic and scarlet hose. A flicker of amusement curled his lips. You are obviously no threat, that thin smile seemed to say. I don’t need to waste any time on you.
Without speaking, he turned and walked away. Leonardo felt insulted and relieved at the same time. Taking advantage of the open door, he stepped cautiously into Maestro Silvestro’s chamber.
The artist was standing at the far end of the room with his broad back to the doorway. He was grumbling angrily to himself as he poured a cup of wine. He tossed the drink back in one swift draught, like a man throwing water over a blazing fire, and immediately refilled his cup.
“I’ll skewer him, that cut-throat, if he talks to me like that again,” Leonardo heard him growl.
He paused inside the doorway, uncertain what to do next. See and understand, Maestro Andrea had told him. He studied the artist in silence. He noted that Silvestro’s once expensive clothes had been sewn up and patched many times over. That suggested he had once been a prosperous artist who had fallen on hard times. The fact that the clothes hung about his body in loose folds meant he had also grown thinner. Probably through guzzling jugs of wine in place of his meals, Leonardo guessed.
He peered around as Silvestro continued to mutter bitterly into his cup. Immediately to his right stood the master’s desk, its surface cluttered with coloured vials, lengths of decorative framing, and jars of powder and ink. Leonardo’s eye was immediately drawn to a large sheet of paper that lay in the midst of the confusion. It was covered in drawings the like of which he had never seen before.
He took a furtive step closer to the desk. The page was crammed with intricate diagrams of notched wheels, pulleys, rods and weights, all fitted together into a complex mechanism.
Is this what the two men were arguing about? Leonardo wondered. And if so, what is it?
He had seen arrangements of cogs before, in the watermill on his family property at Anchiano, but nothing quite like this. Once he had even seen something similar inside an expensive clock that Maestro Andrea was embellishing for one of his clients. But this device was not exactly like that either.
What was it they had said about destruction?
He peered intently at the diagram, trying to piece together in his mind what would be the consequence of the weights moving, of the cogs turning one against the other. With one finger he began to follow the lines, tracing out the possible movements of the device. He was so absorbed in his study he was taken completely by surprise when a beefy hand clamped on to his shoulder.
“Who the devil are you?”
Maestro Silvestro spun the boy around and glowered at him suspiciously. His coarse, jowly face was nearly as red as the droplet of wine that was trickling down his chin. He grabbed the corner of the drawing between two fingers and flipped it over, hiding the diagram.
“What are you doing here, thief?” he demanded.
His breath gusted over Leonardo and the wine fumes almost made him swoon. He tried to wriggle loose, but Silvestro’s thick fingers just tightened their grip on his shoulder.
“I am no thief,” Leonardo protested. “I was sent here by Maestro Andrea del Verrocchio.”
“A spy!” Silvestro exclaimed. “That pig has sent you here to steal my secrets and turn them to his own profit. Well, whatever you have seen, it will do you no good.”
Silvestro’s fingers dug into his shoulder with bruising force.
“I’m no spy either,” Leonardo persisted desperately. “I am simply delivering a message.” He groped for the sealed note and handed it to the artist as a peace offering.
Silvestro scowled at the letter without taking it. “What is it?” he demanded.
Leonardo squirmed, realising that a demand for money would only enrage Silvestro further.
“It did not befit my lowly station to inquire,” he said, laying the paper down gingerly on the edge of the table. “But I am sure it is a message redolent of the deep respect Maestro Andrea has expressed for you on many occasions. Do not trouble yourself to open it until you have the leisure to enjoy its eloquent contents to the full. Perhaps tonight after supper…”
Silvestro’s grip loosened slightly. Leonardo wriggled free and backed out of the door. He retreated across the workshop, bowing as he went, only too well aware of the apprentices sniggering at him. When he saw Silvestro take a step towards him, Leonardo swung round and raced out into the street.
He beat a hasty retreat from the unsavoury neighbourhood of the Oltrarno and did not slow his pace until he was safely across the Ponte Vecchio. On the north side of the Arno, he paused for breath, leaning on a wall and gazing down into the water.
The sight brought back the memory of a day last year when Leonardo had perched on a rocky ledge hanging out over the same river many miles to the north. He had longed then to spread his arms out like wings and fly off like a bird, leaving behind the dull routine of the family farm.
Distracted by his daydream, he had lost his footing and plunged headlong into the river. Flailing about in the water, he had managed to grab the trailing branch of a bent old tree and pull himself up. If not for that, Leonardo might have been sucked under by the current and drowned.
The memory was enough to set his heart pounding like a hammer. Turning abruptly away from the river, he hurried up the street into the heart of the city.
The Piazza della Signoria was filled with noise and bustle. All around the vast open square, merchants, entertainers, preachers and politicians were vying for the attention of the passers-by. A large crowd had gathered before the steps of the palace where the Signoria held their meetings. An excited figure was haranguing them, waving his clenched fist in the air as he spoke.
“This is what the Medici will bring down upon us, a war with Venice,” he warned shrilly. “And for what? For the sake of an upstart who is the son of an upstart, a bandit who has stolen the title of Duke of Milan.”
The crowd booed the name of Medici and yelled in agreement with the orator. One man dared to call out against the speaker only to be quickly silenced by his neighbours.
From the other side of the square Leonardo could hear another speaker loudly praising the Medici to the cheers of his audience. Here and there he saw people accost strangers and demand their opinion with sharp voices and upraised fists.
In the past he had heard many noisy arguments being waged in this square, but they were usually resolved with a jug of wine and good-natured laughter. Over the past few weeks, however, these lively debates had become charged with hostility and threats of violence.
