It was under circumstances such as these that two young Greeks, brother and sister, the brother older, the sister younger, than Agellius, came to Sicca at the invitation of Jucundus, who wanted them for his trade. His nephew in time got acquainted with them, and found in them what he had sought in vain elsewhere. It is not that they were oracles of wisdom or repositories of philosophical learning; their age and their calling forbade it, nor did he require it. For an oracle, of course, he would have looked in another direction; but he desiderated something more on a level with himself, and that they abundantly supplied. He found, from his conversations with them, that a great number of the questions which had been a difficulty to him had already been agitated in the schools of Greece. He found what solutions were possible, what the hinge was on which questions turned, what the issue to which they led, and what the principle which lay at the bottom of them. He began better to understand the position of Christianity in the world of thought, and the view which was taken of it by the advocates of other religions or philosophies. He gained some insight into its logic, and advanced, without knowing it, in the investigation of its evidences.

Nor was this all; he acquired by means of his new friends a great deal also of secular knowledge as well as philosophical. He learned much of the history of foreign countries, especially of Greece, of its heroes and sages, its poets and its statesmen, of Alexander, of the Syro-Macedonic empire, of the Jews, and of the series of conquests through which Rome advanced to universal dominion.

To impart knowledge is as interesting as to acquire it; and Agellius was called upon to give as well as to take. The brother and sister, without showing any great religious earnestness, were curious to know about Christianity, and listened with the more patience that they had no special attachment to any other worship. In the debates which ensued, though there was no agreement, there was the pleasure of mental exercise and excitement; he found enough to tell them without touching upon the more sacred mysteries; and while he never felt his personal faith at all endangered by their free conversation, his charity, or at least his goodwill and his gratitude, led him to hope, or even to think, that they were in the way of conversion themselves. In this thought he was aided by his own innocence and simplicity; and though, on looking back afterwards to this eventful season, he recognized many trivial occurrences which ought to have put him on his guard, yet he had no suspicion at the time that those who conversed so winningly, and sustained so gracefully and happily the commerce of thought and sentiment, might in their actual state, nay, in their governing principles, be in utter contrariety to himself when the veil was removed from off their hearts.
