The contractor, like the seller, is enjoined by law to charge the simple value of his work; in a free city, art should be a true thing, and the artist must not practise on the ignorance of others.

On the other hand, he who has ordered any work and does not pay the workman according to agreement, dishonours Zeus and Athene, and breaks the bonds of society.

And if he does not pay at the time agreed, let him pay double; and although interest is forbidden in other cases, let the workman receive after the expiration of a year interest at the rate of an obol a month for every drachma (equal to 200 per cent.

per ann.).

And we may observe by the way, in speaking of craftsmen, that if our military craft do their work well, the state will praise those who honour them, and blame those who do not honour them.
