“Or a slave, I expect,” said Rachel, as Agis hurried on in front. “They had slaves in Greece, didn’t they?”

“Now we shall see the inside of a Greek house as it was thousands of years ago,” returned Diana eagerly.... “Isn’t this a splendid adventure?”

They found themselves in a passage which led into a square courtyard roofed by the blue sky. A colonnade ran the length of the four sides of this courtyard, and from it on the side away from the open space, they saw various rooms. Agis pushed back a door, and called to the children to follow him.

“It is past noon,” he said, “and our meal is already served. Enter and eat with us.”

Full of curiosity, Rachel and Diana followed the boy into a room whose walls were covered with large black panels upon which were painted figures in brilliant colours. Surrounding each panel there was a rich border of painted flowers. In the midst of the room, placed on trestles, was a table, at which the men of the family were already seated. The father, a middle-aged man, dressed very much in the same fashion as Agis, except that he wore a saffron-coloured instead of a white cloak, looked up and smiled as the boy entered. But he took no notice of the two little girls, and they felt quite sure he neither saw nor heard them.

Seated near to him was a very handsome young man who looked about nineteen or twenty. Except that his curly hair was dark and his eyes brown, instead of grey, he was so like Agis that the children knew he must be the brother Phidolas, of whom he had spoken.

Agis swung himself into his place at the table, which was spread with dishes containing olives, figs, a sort of cream cheese, and flasks of wine, and passed some of these things to his invisible guests.

“Phidolas and I are, as a matter of course, in training for the games,” he said. “Therefore we must eat only of such diet as this. But it may be that simple food pleases you? Eat and drink, and fear no questions from my father and brother. The magic of Sheshà protects you, and they are ignorant of your presence.”

Rachel and Diana were too interested to care much for food, though the ripe figs they tasted were delicious. They cast quick glances about a room so strange to them, and noticed that it contained scarcely any furniture. Except for the simple trestle table, and the chairs round it which were of a beautiful shape and had curved arms, there were only two tripods, each holding an elegant vase, placed in corners against the walls. The door opened upon the colonnade, and beyond it they saw the courtyard with its roof of wonderful blue sky.

“To-morrow at this hour we shall be upon the journey!” exclaimed Agis, addressing his brother. “And at this hour three days hence thou wilt without doubt be in the midst of the race, Phidolas!”
