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 to see something that is rich and rare in other states, or himself to show something in like manner to another city.

Let such an one, then, go unbidden to the doors of the wise and rich, being one of them himself: let him go, for example, to the house of the superintendent of education, confident that he is a fitting guest of such a host, or let him go to the house of some of those who have gained the prize of virtue and hold discourse with them, both learning from them, and also teaching them; and when he has seen and heard all, he shall depart, as a friend taking leave of friends, and be honoured by them with gifts and suitable tributes of respect.

These are the customs, according to which our city should receive all strangers of either sex who come from other countries, and should send forth her own citizens, showing respect to Zeus, the God of hospitality, not forbidding strangers at meals and sacrifices, as is the manner which prevails among the children of the Nile, nor driving them away by savage proclamations.
When a man becomes surety, let him give the security in a distinct form, acknowledging the whole transaction in a written document, and in the presence of not less than three witnesses if the sum be under a thousand drachmae, and of not less than five witnesses if the sum be above a thousand drachmae.

The agent of a dishonest or untrustworthy seller shall himself be responsible; both the agent and the principal shall be equally liable.
