"After the spectators had taken their seats, a signal was given and the doors of the cages were flung open. The furious beasts would rush out and frightful scenes would follow. The creatures were either set against each other or against men who had been sentenced to death." "And would people go to see such terrible things for their own pleasure?" asked Tessa. Her face was full of pain at the idea. "Yes, my dear. It showed that the city was in a bad state when the Romans could take delight in seeing other creatures suffer, whether they were men or beasts," was the answer. "But I told you that we of to-day hold the place sacred to the Christians. That is because in those sad times they were cruelly put to death here. One good bishop, I remember, was killed by lions in this very spot. But he went to his death cheerfully,--he was glad to be a martyr to his faith." "It looks bright and pleasant now," said Mrs. Gray. "It is hard to believe that such dreadful things ever took place here. See the pretty vines growing out between the stones in the wall; and listen to the shouts of those boys as they run and jump among the ruins." As the children seemed ready for a change, Mr. Gray proposed that they should visit the Capitol, where they could see many beautiful statues; after which, they must go home, for the afternoon was nearly gone. That evening Lucy took her place on one arm of her father's chair and told Tessa to take the other. "Now, boys," said she, "stop talking and be quiet, and perhaps father won't be too tired to tell us about the building of Rome. Will you, father dear?" Mr. Gray could never refuse his little daughter when she spoke like that. And if this had not been enough, there were Tessa's great soft eyes looking at him. They seemed to say, "Oh, do, please, tell us," although Tessa herself was too shy to ask him with her voice. "About Rome, you say. All right. "Once upon a time there were two little boys--" "But when was this 'once upon a time?'" interrupted Arthur. "You began the story of Æneas with the very same words." "It was quite a while after Æneas settled in Italy. The two boys were his great-great-great-grandchildren; thirteen times great, I believe. Their mother was a vestal virgin,--that is, she was a maiden who tended the sacred fire in the temple of the goddess Vesta. Such maidens were treated with great honour, but they were not allowed to marry. "So the people were very angry when the young girl claimed that the god Mars was her husband, and that the two baby boys were his and her children. So the poor girl was buried alive, while the helpless babies were put in a trough and set afloat on the river Tiber." "Poor little things! Were they drowned?" asked Beppo. "No, for if they had been, there would be no more story to tell," said Mr. Gray.
