Valazquez painting and relatedness

I choose the passage on page 15 in the first paragraph to summarize the importance of the Valazquez painting. It goes as follows:

"These three 'observing' functions come together in a point exterior to the picture: that is, an ideal point in relation to what is represented, but a perfectly real one too, since it is also the starting-point that makes the representation possible. Within that reality itself, it cannot not be invisible. And yet, that reality is projected within the picture - projected and diffracted in three forms which correspond to the three functions of the ideal and real point."

Foucault goes on explaining who the three functions are which consist of the painter, mirror and observer. This immediately brought me back to the Borges story about the circular moons that Dustin told to us. The reality or the picture that we are looking at is similar to the reality with the three wizards in "Circular Moons." The statement Within the reality itself, it cannot not be invisible. This states that the ideal point is invisible to the objects in the reality of the painting, just like the wizards were invisible to each others reality. This is a great example of Ferdinand de Saussure's structuralism theory of signifier and signifie relationship. All three functions have their own order. To the left is the artist which is a sign of the Valazquez and concept of an artist which is the signifie. To the right is the stranger which is struct by the subject and signifies confusion since we can not be sure of his intentions. And then their is the mirror which purpose is to reflect the subject. The three functions have an accidental relationship with each other, with out even knowing it, through their function towards the subject, just like Borges story. The real point which is the relation between the three functions helps come into question the ideal point, which is the subject of the painting itself (King Philip IV and his wife) which is invisible in the reality of the painting.

The subject is a starting point to a system that involves all three of the 'observing' functions. The system connects the observer in the doorway who imposes an opening that brings light into the system. This light effects the subject that in-turn effects how the artist views the subject. The adaptation of the artist function changes the image in the mirror. The subject can see the mirror image of the representation of themselves and transform the system to change completely. All parts of the system itself can effect the point real or imaginary without even knowing it. And even though each objects purpose is arbitrary to the other there is still a relatedness between the three.
