‘You have a good physique for a boy,’ the athlete said. He rolled off his prospective pupil and offered him a hand. ‘But any time you offer a test of strength to a man, he’ll beat you.’

The new coach had the shoulders of a bull. He stood a head taller than his twelve-year-old student, and he was wider - deep of chest, and with the sort of muscles that decorated heroic vases. His name was Theron, and he had competed for the laurel at Nemea and at Olympia and lost - narrowly - at both. He had come a long way to be the boy’s coach, and he made it clear that he wanted to see what he was getting.

What he was getting was a slim figure with the muscles of a boy - an athletic boy, but he had neither weight nor breadth. He was handsome enough, with a shock of dark brown hair and wide-spaced eyes. His body was well enough formed, his nose as yet unbroken, and he had not yet sprouted the hair of adolescence.

The boy grasped his teacher’s hand and popped to his feet. He gave a petulant smile and rubbed his hip. His shins were decorated with bruises, the brown blotches so regular that his mother said that he looked as if he was wearing Scythian trousers. ‘I’ll have you someday,’ he said. Then he relented and grinned, wondering if that was too brash.

Theron shook his head. ‘You’ve speed and talent, boy, but that chest of yours will never have the width to put my head in the sand.’

The boy bowed, a natural movement devoid of servility. ‘As you say,’ he said. He didn’t mean it, and his attitude came out clearly in his delivery. In fact, there was a tinge of mockery to the sentence. He glanced at his tutor, another big man, who reclined under the stoa of pillars.

The athlete’s resentment showed in his suddenly red face.

The boy’s sister, perched in the cool arch under the colonnade, laughed.

The new coach - the prospective coach - spun. ‘Girl!’ he said. ‘You are not allowed in the palaestra.’ He inclined his head. ‘Young mistress.’ He moved a hand to cover his privates.

The males were both naked.

The ‘young mistress’ rose from her concealment. ‘I disagree,’ she said. She was wearing a man’s chiton over her slim hips and long legs. She was also twelve years old, with the first sign of her mother’s deep breasts and with large and adult eyes of no particular colour. ‘My mother will insist, if you like. I, too, wish to learn to fight the Greek way.’

Theron, a born athlete who had travelled three thousand stades across the Euxine to take a contract that would make him a wealthy man in Corinth for the rest of his life, stood his ground. ‘It is unseemly for women to take part in athletics,’ he began.

‘Spartan women take part in all the games,’ the girl said. ‘My tutor tells me so.’ Her eyes flicked to the big man reclining under the colonnade.

‘When he’s sober,’ her brother added. He picked up a strigil and began to scrape the sand off his backside. ‘And he says women run at Nemea. You competed at Nemea, did you not, Theron?’

Theron looked from one to another, and a slow smile caught at the corners of his mouth. But while the boy was watching the smile, he reached out one hand at the end of a giant arm and grabbed the boy, rotated him and tripped him over an extended foot, pinning him in the sand. ‘In the palaestra, I am master,’ he said. ‘Your sister should not be here. When she returns from making her treaty, I will speak to your lady mother about the women’s events - I would be happy to teach a child with such long limbs to run. But not pankration. Pankration is for men. It is for killing.’

The girl nodded. It was clear from her posture that she was nodding from courtesy, not in agreement. ‘My mother has killed fifty men,’ the girl said. ‘You?’ She nodded before he could answer. ‘I’ll expect a daily lesson from you, then,’ she said to the recumbent form of her twin brother. ‘It will be good for you to teach me. You’ll have every lesson twice.’

‘Master, may I get up now?’ the boy asked.

Theron leaped to his feet and again extended his arm. ‘Of course.’ He turned his back on the girl and confronted his new pupil. ‘Does your sister watch you train?’ he asked.

The boy laughed. ‘She trains with me,’ he said. ‘Master.’

Theron shook his head. ‘Not until I have spoken to your lady mother. Young mistress, please leave the palaestra.’

The girl nodded again, a slow gesture that was identical to her brother’s nod. ‘We will speak of this again,’ she said. She rose to her feet with muscled grace, showing none of the coltishness of her age, and walked out of the arches, heading to the baths. She paused at the archway. ‘You should call us by our names,’ she said. ‘That is the policy of my mother, and it is a good one. I am not the mistress here, any more than you are master. I am Melitta. My brother there is Satyrus. We are the children of Kineas of Athens and the Lady Srayanka. Our family fought at Marathon against the Medes and on the sea of grass against Darius. My father was descended from Herakles, and my mother from Artemis.’ She bowed her head. ‘The only mistress here is my mother, and she has no master.’

Theron didn’t know many twelve-year-old girls in Corinth who could stare him down. She hadn’t blinked since she had begun to talk. ‘I understand that your father is dead,’ he said.

The girl - Melitta - gave him a long look. ‘We will speak of this again,’ she said, and went into the baths.

Theron turned back to his proper charge - Satyrus. ‘I said three falls,’ he said. He glanced over his shoulder as if to make sure that the girl was gone.

‘Was that one fall, or two?’ the boy asked. There was no wickedness to his question. He meant it just as he asked it. ‘Master?’ he added, a little late. Have to watch that if I want to keep him, Satyrus thought to himself.

Theron swung his arms. ‘That was one fall,’ he said. ‘Are you ready?’

The boy took up his stance. He was confident in his postures - his tutor knew the pankration well enough to teach a boy. Theron stood without moving, and Satyrus held his stance for as long as it took him to draw twenty breaths and release them slowly. He held it well, his hands high, weight well distributed, left foot forward and ready to kick. Theron began to circle and Satyrus circled with him, carefully keeping his distance. He had misjudged Theron’s immense reach the last time. Now he was careful.

Theron lunged in, moving from his left foot to his right and reaching with his arms. The boy blocked one of his reaching arms and kicked hard at his knee, but Theron moved a fraction and took the kick on the side of his leg. He grunted.

‘Good kick,’ he said as he backed away.

Satyrus flashed a grin and moved in to attack, spun on his front foot and kicked again.

Theron grabbed for the leg - he had expected another kick - and grasped air. The second kick was a feint.

Satyrus whipped the kicking foot around, spinning his centre of gravity. He closed, grabbing Theron’s extended hand with both of his own and throwing his weight to rotate the arm.

Theron’s other arm shot out and grappled the boy’s shoulders, pulling at him, grasping for a hold to turn the boy’s body and take the weight off his arm.

Satyrus was too small to resist that grapple long. Desperate, he bit the older man’s left bicep, drawing blood.

Theron shouted and punched him in the head and Satyrus’s whole body moved with the strength of the blow, but he set his jaw and tried to hold his grip on the sweat-slick muscles of his opponent’s arm. Pressed almost ear to chest, he could hear Theron’s heartbeat racing as he sank to one knee under the pressure of the boy’s attack on his shoulder joint.

Theron’s second blow to his head broke his hold, and Satyrus fell bonelessly to the sand. It wasn’t that he decided to relinquish his hold - the strength just flowed away from his limbs. He wondered if he was going to die, as men did in the Iliad when the strength left their limbs. His vision tunnelled and the palaestra began to go away. But he could still hear. He heard the big Corinthian get to his feet, his hands brushing away the sand. He heard the sound of someone clapping.

‘Good thing that you won,’ came the voice of his tutor. He sounded drunk and sarcastic. ‘Embarrassing to lose to a new pupil. Knocking him unconscious will probably teach him a lesson, too.’

The new coach sounded upset when he replied. ‘I never meant to hit him so hard,’ he said. ‘Apollo - I’m bleeding like a sacrifice.’ He shifted his weight. Satyrus could hear everything. He could hear the sound of the man breathing. ‘I regret that,’ he said.

The tutor rose unsteadily, his feet scraping loose sand on the marble floor as he stumbled, every grain giving its own sound to Satyrus’s ears. Then he crossed the sand. Satyrus heard the uneven sound of his footsteps, even on the sand, heard him fetch a canteen from the far wall and felt the cold water hit his face as he sprinkled the contents liberally. Satyrus felt his eyelids flutter of their own volition, and light came to his eyes like a bolt of pain.

‘Ugh,’ Satyrus said.

He tried to sit up, and after a few heartbeats he managed the trick, only to fall on all fours and vomit up his barley porridge. He still had some of Theron’s blood on his mouth.

Theron knelt at his side. ‘Can you understand me?’ he asked.

‘Yes,’ Satyrus replied. ‘Master.’

Theron nodded. ‘You scared me,’ he said. He shrugged. ‘I applaud you. That any boy could scare me like that is, in itself, a kind of victory. I will take you seriously. Now promise me that you will not bite or gouge in a contest. It is against the rules.’

‘Not in Sparta,’ said the tutor. He wiped the boy’s mouth with his chiton.

Theron sat back on his heels, his puzzlement plain on his face. It was clear from his expression that he couldn’t decide if the tutor was a peer or a slave. He had a paunch and his hair was thinning on top, and he was clearly drunk - functional, the way many hard-drinking slaves went through life, but drunk nonetheless.

The room was spinning around Satyrus, and he was in no mood to help the new man. Besides, if he couldn’t see that the pins of his tutor’s chiton were gold, he was a fool.

The drunkard leaned forward. ‘You going to live, boy?’ he asked. The smell of sour wine washed over Satyrus, and he retched again. When he was done, he extended a hand to his tutor.

‘Yes, master,’ Satyrus replied. He had no trouble calling the drunkard ‘master’.

But Theron had obviously not risen to be a champion by underestimating his opponents. ‘You are a Spartan,’ he said to the tutor.

The other man nodded. ‘I was a Spartan,’ he said. ‘Now I am a gentleman of Tanais.’ The Spartan’s wit dripped with self-mockery.

‘Theron of Corinth,’ the athlete said, extending his hand.

‘Philokles,’ the other man said, accepting Theron’s hand. Theron made a face suggesting that the Spartan had quite a grip for a drunk.

The two big men watched each other for a few heartbeats. Theron grinned. Philokles smiled slightly.

‘Can I get up now?’ the boy asked. He rubbed his temple. ‘Everything is moving around,’ he said.

Theron pressed with his thumb at the impact point, his heart pounding, and he showed his relief with a sigh when he found nothing moving under the pressure while the boy tried to hold his head still against the pain. ‘No more fighting today,’ he said. ‘And no afternoon nap. Sleeping after a heavy blow is dangerous.’

Philokles nodded at the Corinthian. ‘You’ve read the Hermetics?’

Theron nodded. He raised an eyebrow at the tutor, whose smile broadened.

‘I feel better,’ the boy said. Lies. But the lies of virtue. ‘Let’s have a third fall.’

‘No,’ Theron said.

‘Let’s go fishing,’ Philokles said. ‘A pleasant way to spend a spring day. Aesop would approve, and Xenophon wrote a book on it.’ The Spartan rose to his feet. ‘I’ll find some lines and some wine. Meet me at the stables before the sun is at the zenith.’

He bowed.

Satyrus returned the bow, a little unsteady. He went across the sand under his own power and headed for the baths.

‘Do you fish?’ he heard Philokles say. His ears were ringing and it was all he could do to walk without putting his hands on the columns for support, but he had done other things as hard.

‘My father was a fisherman,’ Theron said.

‘I’ll take that to mean no,’ he heard Philokles say, and then he was safe within the steamy warmth of the archway.

Between the salmon and the wheat, the town was already rich.

The town itself was a small affair centred on a temple to Nike and the accompanying baths and palaestra of a much grander town, built in wood on stone foundations and decorated in the latest fashion. The ivory and gilt statue of the goddess was the dedication of two of the town’s most prominent founders: Diodorus, a soldier of fortune currently far to the south in service to Eumenes the Cardian, and Leon the Numidian, one of the Euxine’s principal merchants. Their names appeared on the founding stones of the temple and the palaestra, on the stone stele to the dead of the town and on the marble plinth at the corner of the new law court. Leon owned the warehouses at the edge of the water, and the stone wharves, and his contributions had dredged the harbour and raised the breakwater that had turned a chain of tiny islands into an impregnable defence against the Euxine’s occasional winter storms.

The Lady Srayanka, the mother of the twins, was not a Greek woman. Her name appeared on no dedications. No founding stone had her initials, and none of her weapons were dedicated at the altar of Nike, but her hand was visible all along the river. As ruler - queen, some said - of all the Eastern Assagatje, it was her word that kept the settlement free from the predations of the tribes of the sea of grass, and her warriors that made the town independent of the labyrinthine politics of the nascent kingdom of the Bosporus to the west. In her name, the Sindi and the Maeotae farmers lived in safety along the river valley. Her horsemen and the hippeis of the town kept the bandits away from the high ground between the Tanais and the distant Rha, so that merchants like Leon could bring their precious cargoes from the Hyrkanian Sea far to the east - and farther, from Seres itself, and Qin.

Satyrus was her son, and Melitta her daughter. They walked through their town, hand in hand, to the stables built in their father’s name, in the hippodrome where their father’s friend Coenus still drilled the remainder of the men who had followed their father east in his fabled war with Alexander. Most of them were away in the south with Diodorus, on campaign, as mercenaries.

‘How’s your head now?’ Melitta asked.

Satyrus blinked. ‘For some reason,’ he said slowly, ‘it’s worse in the sun.’

They entered the hippodrome - a building that was new and well-built and out of all proportion to the number of cavalrymen that the town actually supported. Satyrus gritted his teeth against the ache in his head as they crossed the sand, and squeezed his sister’s hand until she grunted in pain.

‘Sorry,’ he said.

They passed the line of columns at the edge of the stables - wooden columns, but carefully painted to look like marble - and the smell of horses enveloped them.

Pelton, an old freed slave of Leon’s, greeted them. ‘The gods prosper you, twins,’ he said. ‘Master Philokles took a mule. That new feller - too big for a mule - he took a horse.’

Twins was something like a title in Tanais. Melitta nodded. ‘I’ll take Bion,’ she said. Bion was a Sakje charger, bigger than a Greek pony, like a warhorse scaled for a tall girl. She called the beast ‘Bion’ because the gelding was her life. Happy or sad, angry or elated, she dealt with the rigours of life by riding. Twice now, she had gone with her mother to the summer pasture of the Assagatje, riding with the maidens while her brother learned philosophy and law in faraway Athens. Her horse was her answer to most things.

Satyrus walked down the line of stalls until he reached the end, where his father’s charger cropped barley straw with the contentment of a retired warhorse. ‘Care to go for a ride?’ he asked the giant. Thalassa was a mare - but a mare of heroic proportions. She raised her head and nuzzled him for a treat until he produced a carrot. Then she chewed the delicacy with a finicky patience, tossing her head.

‘You want to go?’ he asked again. ‘I think the answer is yes.’

The former slave laughed. ‘When has the answer ever been no? Eh? Tell me that!’ He stepped in and put a bridle on the old mare in a single motion, his lower hand putting the bit into her mouth without so much as a jingle of the bronze against her teeth.

Melitta put her palms flat on her horse’s back and sprang on to her in one go. ‘Pelton, do you ever wonder why you were a slave?’ she asked.

Pelton looked at her for the time it took an insect to cross a leaf. ‘Nope,’ he said. ‘Will of the gods, mostly, I expect.’ He plucked a piece of grass and put it in his mouth.

‘Could happen to anyone, couldn’t it?’

‘Sister!’ Satyrus didn’t always appreciate his sister’s approach to the world - a blunt approach, to say the least.

She looked down at him from her horse. ‘Well, Leon owned him. And Leon was a slave. So Leon should know better.’

‘Better than what?’ Satyrus asked. He liked to think that he was already a man - a man who understood things. One of the things he understood was that you didn’t tease slaves about their slavery.

‘Better than to own people,’ she said.

Satyrus rolled his eyes. He led Thalassa out of the stable, her heavy hooves ringing on the cobblestone floor and sending pings of echo off the whitewashed walls to penetrate his brain and increase his headache. He led her around to the mounting step and climbed on to her, sitting well back, as a boy can on a big horse. He adjusted his gorytos and then leaned over to his sister. He could see Philokles down by the gate, arguing with Theron. ‘It’s not nice to talk to slaves about slavery.’

‘Why not?’ Melitta asked. ‘Pelton was a slave. Who else would I ask? You?’>

Satyrus made the sound that brothers make all over the world, and tapped Thalassa’s sides with his bare heels, and the mare surged into motion. Satyrus could feel her power - even at the age of seventeen, she was a big animal with power and spirit, the veteran of a dozen battles. When he was on her back, he could imagine that he was his father at the Jaxartes River, about to crush Alexander.

Pelton emerged from the stable with a scruffy straw hat clutched in his fist. ‘This’ll help, male twin.’ Satyrus wheeled the mare in a neat curve and snatched the hat and pulled it on. The shade of the broad brim was like a healing balm.

‘All the gods bless you, Pelton!’ Satyrus said.

‘And you, twins!’ the former slave called.

‘My sister means no harm,’ Satyrus said.

Pelton smiled. ‘Hope she never has to find out for herself,’ he said, before he went back into the stables.

In Athens, on the other hand, many men spoke ill of their father, and a year ago Satyrus had attended the legal proceedings that had finally revoked his father’s conviction for treason, making Satyrus a citizen and returning his grandfather’s fortune. Which had only served to prove what every twelve-year-old knows by heart: the world is far more complicated than it appeared when you were ten.

‘Surely Plato argues the point convincingly,’ Theron began, as if he’d already made this argument and was still awaiting some acknowledgement.

Philokles had a leather bag over his shoulder. He tapped his mule into motion. Theron was mounted on a tall horse, one of the town’s cavalry chargers, and he towered over the Spartan, but he had to thump the horse’s sides to get him into motion. In a few surges of the charger’s hindquarters it was clear that the Corinthian wasn’t much of a rider.

Melitta was looking at the eastern horizon as if following her dead father’s hand. The town sat on a bluff, and she could see a parasang, thirty full stades, or more in the early afternoon sun. ‘Is that smoke?’ she asked.

Philokles looked under his hand, and so did Satyrus.

‘I expect they’re clearing new fields,’ Satyrus said. He regretted his tone almost at once - hectoring his sister with a display of knowledge when he didn’t actually know what he was talking about. I must outgrow that, he thought.

She glanced at him and gave him half a smile, as if she could hear every word of his interior dialogue. ‘Leon’s still away,’ she said, indicating the empty wharves as they rode through the gates.

‘Leon the Numidian is our richest citizen,’ Philokles said to Theron, who was more interested in mastering his horse than in the town’s social life. ‘Married to a barbarian. Wonderful horseman. A well-rounded man, for all that he started life as a slave.’

‘Even in Corinth I’ve heard of your Leon,’ Theron said. ‘Whoa!’

‘It will do you no good to lose your temper at a horse,’ Melitta said. She laid a hand on Theron’s bridle and stroked his gelding’s neck and the horse calmed. ‘That’s quite a squadron for this time of year,’ she said, pointing out to sea.

Satyrus looked. At first he saw nothing, but after a moment he could see a line of sails just nicking the edge of the world, three or four hours out in the bay. ‘Triremes,’ he said, because the sails were matching sizes. Closer in, a pentekonter raced for the beach under full oars.

‘Is that mama’s boat?’ Satyrus asked. He was relieved to see it.

‘Early for our mother,’ Melitta said. But she smiled. They both wanted her home.

Theron glanced at her and looked away, changing weight and sitting too far back on his horse. The horse sensed his inattention and decided to be rid of him. He half-reared and then shot forward and Theron landed on the road like a sack of barley. The gelding raced away.

‘Oof,’ he said. Then he lay still.

Satyrus put a hand on his borrowed straw hat and leaned forward, the change of his weight enough to push Thalassa into a gallop, and he raced across a field of new emmer wheat that rolled away to the east, broken only by boundary walls and the line of the road. He caught the gelding easily, turned Thalassa under the offending horse’s nose and caught his dangling reins. ‘Come on, Hermes,’ he said. Hermes was a gelding who missed his prick and tended to take it out on his riders. Satyrus stood up on Thalassa’s back and jumped on to the gelding, pulled the reins and began speaking a litany of nonsense to him. The gelding turned and trotted back to the group, and Thalassa followed along, riderless but obedient.

When he was within range of her voice, Melitta called out, ‘Can you handle him?’ just to annoy her brother, who responded by prodding the gelding to a gallop and racing through the middle of them, scattering dust and almost riding his new coach down.

‘Sorry!’ he said. By way of apology, he handed the Corinthian the reins to his father’s warhorse. ‘Master Theron, this is the smartest horse who ever lived. She’s the mother of half the cavalry horses on this side of the Euxine and she’s still the toughest thing on four legs. Just don’t sit so far back on her rump.’

The athlete made a poor showing of mounting the tall horse without a step, but he got up on his fourth try. Melitta didn’t hide her laughter. Theron glared at her, and then at Philokles.

‘Is this the order you maintain, master tutor?’ he asked.

Satyrus caught his sister’s eye, and they rode a little apart. Close enough to listen - far enough to give the appearance of privacy.

‘If you mean Plato’s views of the soul as he - rather mean-spiritedly, I might add - puts them in the mouth of Socrates, I’d say that they’re interesting, but scarcely irrefutable,’ Philokles said.

‘You dislike Plato?’ Theron asked.

‘I dislike a sophist whose underlying theme is that he’s smarter than his audience. Name me one dialogue where Plato is bested by a student.’ Philokles wasn’t looking at Theron but at Satyrus, who shook his head and smiled, because no such dialogue existed.

Theron shrugged. ‘I doubt such a thing happened,’ he said.

Philokles laughed. ‘Their father studied with Plato until he died. I’m afraid that his tales of his former teacher have left an indelible impression. ’ The Spartan smiled. ‘I prefer Simonides or Heraklitus!’

‘That posturer? He only worked for money!’ Theron sounded outraged.

Satyrus and Melitta grinned at each other, because Philokles said that their father had said that Plato was a pompous ass, which was an image so droll as to evoke giggles even here.

Theron looked at the children. ‘They’re both quite intelligent,’ he said. It didn’t sound like a question.

Philokles nodded. ‘Is breeding people any different from breeding horses?’ he asked. ‘Their sire was a brilliant soldier and an educated man - a decent athlete as well, third or fourth in the hundred-and-ninth Olympiad.’

‘Really?’ Theron asked. ‘What event?’

‘Boxing,’ the Spartan replied. ‘Boys’ boxing. He never competed as a man.’

‘Why not?’ Theron asked. Any boy who could make the top tier would have been a front-runner as a man.

‘War,’ Philokles said. ‘We had quite a bit of it, back then.’

‘No shortage now,’ Theron said.

‘At any rate, the mother’s no different. You’ll see when she’s back from Pantecapaeum. She’s not the beauty she used to be, but she’s a first-rate tactician, she gives a fine speech for a barbarian and she’s a brilliant athlete.’ Philokles looked out over the fields and smiled to himself.

‘She’s a runner?’ Theron asked. Running was virtually the only sport open to Greek women.

Philokles’ smile became a grin. ‘She’s an archer - a mounted archer. Perhaps the finest on the sea of grass. And a pretty fair swordswoman.’

Theron nodded. ‘I see. Hence the daughter.’ He glanced at Melitta. Satyrus watched his eyes.

The Spartan nodded. ‘Just so,’ he said.

The twins dismounted immediately, tethered their horses amidst the lush grass, hung their bows on their saddlecloths and went upstream, bronze knives in hand, to cut rods. When they were satisfied with what they had, they came back. Philokles was laying the horsehair lines out in the goat-cropped grass at the edge of the stream. Then the Spartan deftly attached bronze hooks decorated with red thread and hackles the colour of a bay horse.

‘I’ve never seen anyone fish like this,’ Theron said.

‘Come!’ Melitta said, taking his hand. He seemed shy of the contact, but he went with her willingly.

‘Don’t scare the fish,’ she said in a whisper, and went down on all fours to crawl up the big rock that separated them from the stream. She was up the rock in a moment, just her head showing to the fish. She raised an arm carefully, and when the Corinthian was in place beside her, she pointed. ‘See the trout?’ she asked.

Theron watched for the time it would take him to fight a bout, following her pointing finger, breathing carefully. ‘I see it,’ he said.

She was conscious of the warmth of a grown man next to her on the rock. Something to be aware of, she thought. ‘Watch,’ she said. Different from lying next to my brother.

Time passed. She was conscious that he must be bored, annoyed at the passing insects for failing at their duties. But at last a fly slowly came down, one of the big brown flies that the fish loved. It trailed across the water, its abdomen brushing the surface from time to time. Melitta assumed that it was laying eggs - eggs so tiny she couldn’t see them, although she had watched this dance many times.

Her brother crawled up the rock on her left side. ‘Any luck? Oh!’ he exclaimed, as one of the pool’s residents powered up from the dark at the bottom of the pool and took the big insect right off the surface of the water and rolled away in a red-orange flash, leaving a growing circle of ripples in its wake.

Melitta grinned in delight, slipping back down the rock and clapping her hands. ‘See?’ she asked, or rather demanded.

Theron’s grin was lopsided and far friendlier than either of the children had seen from him yet. ‘I do see. This isn’t fishing with nets - it is fishing with insects!’

‘Not real insects,’ Satyrus said. ‘For some reason, even if you catch them, the fish won’t take them. But if you tie some feathers to a hook . . .’ He pointed at the rods of young cornel that Philokles had rigged. The dogwood sticks were the height of a grown man, and the horsehair lines were the same length.

‘And if you dabble the bug on the surface like the real ones...’ Melitta added.

‘Then sometimes - bang! - you get a big fish. They strike like a bolt from Zeus.’ Satyrus took one of the rods eagerly. Melitta grabbed another and untied her sandals.

‘I’m going upstream,’ she said.

Philokles nodded. ‘I’ll go with the young lady.’ He followed her. He seemed sober now, and Satyrus thought that his tutor was as happy as he’d ever seen him. Perhaps he needed company. Adult company. The thought saddened the boy a little. He wanted to be adult company, but he loved the big Spartan, drink and all, and if Theron of Corinth made him happy, so be it.

Satyrus went back to the rock, pondering the Corinthian and his odd reactions to his sister. He moved carefully up the rock, brought his dogwood rod level with his shoulders and flipped the hook over his head. The feathered hook sank through the still air and landed lightly on the water, the feather of the hackle resting on the surface tension.

After a heartbeat, Satyrus gave the gentlest of tugs and the bug skittered across the surface. He took a breath and repeated the motion.

Nothing. He sighed softly and popped the fly back off the water and over his shoulder, the hook arcing through the air and tiny drops of water brushing his skin. Using just his wrist, he flicked the hook back on to the water, took a breath and skipped the fly.

The movement of the fish was so fast that only long afternoons spent at this pastime enabled the boy to pull the hook just right and he had a fish the length of his arm pulling at the end of his rod. He raised the rod and dropped the fish on the cropped grass behind the rock. ‘Will you take it off ?’ he asked Theron, who wasn’t fishing but just watching.

The big man knelt in the grass and took the hook from the fish’s mouth. He bashed the fish on a rock, then pulled out a bronze knife and gutted the fish in two strokes.

‘You’ve done this before,’ Satyrus said accusingly.

Theron smiled. ‘I’ve never seen anyone use a fly like that,’ he said. ‘But my father had a fishing boat. Cleaning fish is the same everywhere, I’d wager.’

Satyrus held out his rod. ‘Want to try?’ he asked.

Theron rinsed his hands in a side pool and reached out for the rod. ‘I’d love to.’

‘Why don’t you like my sister?’ Satyrus asked as the Corinthian flicked his hook on to the water.

‘I don’t dislike your sister,’ the man answered. ‘Do you know that in Hellas, women do not go fishing with their brothers?’

Satyrus could see a rider across the stream. He was a couple of stades away and he was moving so fast that he raised dust.

‘I’ve been to Athens,’ Satyrus said proudly. ‘The girls all had to stay at home.’

‘Exactly,’ Theron said.

‘I thought it was stupid,’ Satyrus added. ‘I think that’s Coenus!’ he said, sliding back off the rock.

‘Who’s Coenus?’ Theron asked politely. A fish chose that moment to hit his lure, and despite his inexperience, he jerked the rod and he hooked his prey - a trout at least as long as his forearm.

‘Well done!’ Satyrus exclaimed with all the enthusiasm of his age. He reached out and unhooked the trout, a big male with a heavy jaw and some fat on his backbone. The big fish had swallowed the hook, and Satyrus pulled carefully at the horsehair line, trying to retrieve the hook - fish hooks were precious.

‘He’s riding hard,’ Theron said.

Satyrus got bloody fingers on the shaft of the hook and pulled, and the hook ripped free of the cartilage, and the big fish spasmed and vomited blood. Satyrus reversed his bronze knife and killed the fish with a practised blow. Then he laid it on the grass and gutted it. ‘Coenus was one of my father’s companions,’ he said as he worked. ‘He’s quite old - older than you. He married a Persian, and keeps the temple of Artemis down the valley. He’s a great hunter. His son is at school in Athens.’ The boy smiled. ‘Xeno is my best friend. Besides my sister, I mean. I wish he was here.’ More soberly, ‘Coenus says that a tutor is no substitute for Athens.’

‘He’s riding fast,’ Theron said, still perched on the fishing rock.

Satyrus raised his head as he dropped the two fish into the net bag he wore. ‘He is,’ he said. ‘Will you excuse me?’

‘There are other riders behind him,’ Theron said, rising to his feet. Something in the posture of the riders disturbed him.

‘Get the horses,’ Satyrus said. ‘I’m going down to the road. Get the horses and the others.’

Theron hesitated, and Satyrus looked back. ‘Move,’ he said. ‘Coenus is bleeding. Something is wrong.’

The Corinthian chose to obey. He jogged off up the trail along the stream.
