Cyropaedia

And any merchant who wishes to accompany[*](and merchants) us, seeking a market for his wares, may do so; but if he is caught trying to sell anything within the number of days for which the troops are ordered to furnish their own provisions, he shall have all his goods confiscated. But when those days are past, he may sell as he pleases. And the man who seems to offer the largest stock of goods shall receive rewards and preferment both from the allies and from myself.
