“A new-born child is in the house without doubt,” returned Agis carelessly. “A boy.”

“How do you know?” asked Rachel.

“If it had been a girl, there would be a wreath of wool, instead of olive leaves. You may see such a one over there,” replied Agis, nodding in the direction of another door further on, where a twisted loop of violet wool hung from a knocker.

The children were much interested.

“It’s awfully nice to know like that about the babies,” declared Diana.... “Where are we going, Agis? What is this place?” she added curiously, as the boy ran on in front of them up a broad flight of steps leading to an imposing building.

“This is the gymnasium, and unless we hasten, I shall be late, and my instructor will be angered.” Agis looked over his shoulder to say this. “Follow me, and pay no heed to anyone, for no one will pay heed to you. Sheshà has put you under my guidance—I know not why. But I know that, except to me, you are invisible. Go boldly into yonder courtyard and watch. I must first leave my garments in the corridor.” He ran quickly down a passage to the right, and the children, full of wonder, walked on into a sunny square, enclosed by high walls, where little boys were going through all sorts of exercises.

“Oh, don’t they look pretty without their clothes!” was Diana’s first exclamation. For all the boys were naked, and as they ran and leapt, and the sunshine fell upon their little white bodies, they did indeed look beautiful.

“He said it was a gymnasium,” said Rachel. “But there aren’t any rings and poles and things, like there are in our gymnasiums. I suppose this was the first sort of gymnasium, and ours are named after it?” she went on suddenly, as the idea struck her.

“There’s Agis!” cried Diana, as the now naked boy appeared. “Doesn’t he look like a statue come to life? Oh, look, Rachel! What is he going to do? That man—I suppose he’s the master?—is rubbing him all over with something. It’s oil, isn’t it? and those other boys are being rubbed with it too.”

“It’s to make them move their bodies easily, I expect,” said Rachel. “You know how oil makes stiff things like rusty locks quite smooth and easy. I suppose it’s the same with people’s joints.”
