nurture, or if he have himself made any observations, let him communicate his discoveries to the whole assembly.  And if he be seen to have come home neither better nor worse, let him be praised at any rate for his enthusiasm; and if he be much better, let him be praised so much the more; and not only while he lives but after his death let the assembly honour him with fitting honours.  But if on his return home he appear to have been corrupted, pretending to be wise when he is not, let him hold no communication with any one, whether young or old; and if he will hearken to the rulers, then he shall be permitted to live as a private individual; but if he will not, let him die, if he be convicted in a court of law of interfering about education and the laws.  And if he deserve to be indicted, and none of the magistrates indict him, let that be counted as a disgrace to them when the rewards of virtue are decided.

Let such be the character of the person who goes abroad, and let him go abroad under these conditions.  In the next place, the stranger who comes from abroad should be received in a friendly spirit.  Now there are four kinds of strangers, of whom we must make some mention—­the first is he who comes and stays throughout the summer; this class are like birds of passage, taking wing in pursuit of commerce, and flying over the sea to other cities, while the season lasts; he shall be received in market-places and harbours and public buildings, near the city but outside, by those magistrates who are appointed to superintend these matters; and they shall take care that a stranger, whoever he be, duly receives justice; but he shall not be allowed to make any innovation.  They shall hold the intercourse with him which is necessary, and this shall be as little as possible.  The second kind is just a spectator who comes to see with his eyes and hear with his ears the festivals of the Muses; such ought to have entertainment provided them at the temples by hospitable persons, and the priests and ministers of the temples should see and attend to them.  But they should not remain more than a reasonable time; let them see and hear that for the sake of which they came, and then go away, neither having suffered nor done any harm.  The priests shall be their judges, if any of them receive or do any wrong up to the sum of fifty drachmae, but if any greater charge be brought, in such cases the suit shall come before the wardens of the agora.  The third kind of stranger is he who comes on some public business from another land, and is to be received with public honours.  He is to be received only by the generals and commanders of horse and foot, and the host by whom he is entertained, in conjunction with the Prytanes, shall have the sole charge of what concerns him.  There is a fourth class of persons answering to our spectators, who come from another land to look at ours.  In the first place, such visits will be rare, and the visitor should be at least fifty years of age; he may possibly be wanting
