THEAETETUS: I have done so.

STRANGER: Then, now, there are in all four parts or segments—two of them have reference to us and are human, and two of them have reference to the gods and are divine.

THEAETETUS: True.

STRANGER: And, again, in the division which was supposed to be made in the other way, one part in each subdivision is the making of the things themselves, but the two remaining parts may be called the making of likenesses; and so the productive art is again divided into two parts.

THEAETETUS: Tell me the divisions once more.

STRANGER: I suppose that we, and the other animals, and the elements out of which things are made—fire, water, and the like—are known by us to be each and all the creation and work of God.

THEAETETUS: True.

STRANGER: And there are images of them, which are not them, but which correspond to them; and these are also the creation of a wonderful skill.

THEAETETUS: What are they?

STRANGER: The appearances which spring up of themselves in sleep or by day, such as a shadow when darkness arises in a fire, or the reflection which is produced when the light in bright and smooth objects meets on their surface with an external light, and creates a perception the opposite of our ordinary sight.
