Pageants as a contract between Elizabeth and her subjects

In this week's readings about Elizabeth's coronation, the thing that struck me most about the pageants is that they subtlety allowed Elizabeth's new subjects to let Elizabeth know what they expected of her as a ruler while at the same time lauding her for possessing these qualities. The pageants position Elizabeth as a ruler who is judicious, merciful, and, most importantly, worthy of the position she into which she has descended. I saw this as an attempt to create a self fulfilling prophecy about what type of ruler she will be by saying hat she already possesses the attributes of a kind and merciful ruler by predetermining what kind of ruler she will be and not leaving room for such antics as persecution. In particular, the pageant with the trees that illustrated the causes of a flourishing and ruinous commonwealth seemed to me to send a message that the subjects know what works and what doesn't on the part of boh the ruler and the subjects. I think there is an interesting psychology behind the pageants and I would like to know more about how they were written and how subjects can get away with basically telling the ruler what is expected of them.
