This was the sixth night. He had lain awake through most of it, listening to the wind, the body of the sleeping boy beside him, beset by fear at still not knowing the sender, fear of other failures that might follow from this. The strands of the wind he knew by this time; tensed in concentration, he imagined he could hold them apart, the shrilling high up among the bare rocks, the softer combing in the shrub lower down, the ripple of loose canvas from the tents. Even the very smallest sounds he strained to hear, random sobs and whispers, stirring of grasses, the faint scrape of displaced pebbles along the shore. A wind from the north-east, unheard of at this season, keeping the fleet trapped in these straits at Aulis, and the army with it, waking the men every morning to the unhappy knowledge of some god's displeasure. It came from the direction of Troy, where lay their dreams of conquest. Six days and six nights with no sigh of relenting, though the voices varied. The wind itself seemed to suffer in all its moods, even in its rages pleading to be quieted, to be soothed.

Then, early in the morning of the seventh day, came the summons from Agamemnon. He noted the time just as in those days of his power he noted all such things. Just before sunrise, the wind still there but quieter now, as if for the while exhausted after its riots in the dark. A time disputed between Hecate and Helius, when the world is between states. He was between states himself, as he also noted: neither inside the tent nor out of it, but cross-legged on a cushion at the threshold, watching his acolyte Poimenos, who was still half-asleep, fumbling together a fire for the infusion of mint and honey he had been schooled to prepare. And he was neither clothed nor naked, being dressed only in a loincloth, with a piece of cotton over his shoulder as a shawl. These were things important to remember and interpret; not mortals but gods chose the times.

It was the chief scribe Chasimenos who brought the message, approaching from the rear, appearing suddenly, flanked by soldiers from the King's Guard. At midday, after the fight, Agamemnon would require the presence in his tent of Kalunas, I beg your pardon, Calchas, priest of Apollo.

He smiled saying this, glancing away with eyes so pale as to seem almost colourless in the narrow, bearded face. Calchas read the usual veiled contempt in voice and smile, the elaborate politeness, the stress upon the name, not his own, bestowed on him by the Greeks. Contempt too for his shaven face, his plaited hair, the smudges of kohl that would be still on his eyelids, the amulets worn as a bracelet, contrary to Greek custom. Asian priest of an Asian god without even a cult centre yet established here.

All this was in the looks and the words – Calchas was practised in reading such marks. But there was also the fact that this upstart diviner had been granted a shelter of canvas when most of the army spent the nights in the open, finding what cover they could; that he had a boy to share his tent and see to his needs; that he slept on a woollen mat, thickly woven; that he need not reply promptly to a messenger, even one of high rank. It was common knowledge that the King would make no decision, take no step, before Calchas had first scanned the auguries.

Chasimenos stood there waiting, in his long-sleeved tunic of a palace bureaucrat. His smile had withered at the delay. 'The King requires the presence of his seer,' he repeated. The soldiers stood on either side of him, their long spears grounded, their faces heavy with ill-humour at being given escort duties at such an hour, not much after dawn. It was early for the King to send; he would have had another bad night. Chasimenos had no need of an escort for such a small thing as this. But the habit of armed guards had grown in the days they had been here, waiting on the wind. Agamemnon himself never appeared without at least six.

He said, 'Calchas will be honoured beyond honour to kneel at the King's feet. May he live for ever.'

As he spoke he heard the small crackle of the fire, saw the smoke rise straight up in a thin plume. He felt a slight shudder within him, premonition of ill. These calms were dangerous, always brief, cheating the army with hope. There was some quality of danger too in this dawn summons to a meeting he had not been consulted about. Nothing of this showed on his face. He had known how to wait before answering, just as he knew now how to appear unaffected.

He had expected, the answer once given, that the other would quit his presence immediately – it was one he had never shown signs of liking, not even back in Mycenae, before they had set out. But Chasimenos remained there, and after a moment, in a tone he tried to make friendlier, said, 'Which of them do you think will win?'

Now at last Calchas could permit himself to show some slight surprise. He was being solicited for an opinion as to who would live and who would die that morning: Stimon the Locrian or Opilmenos the Boeotian, due to fight a duel later on as champions of their respective tribes. 'I have no ideas on the matter,' he said, which was untrue.
