St Peters - Vatican City This is quite the same shot of the Exercise 1. It's very interesting how many informations we can desume from one single view. Now the focus is on the materials. The issue of the materials for the construction of buildings coming from different places in the known world is an ancient issue, at least in our old Europe. What I like to argue from the shot from the point of view of the materials is that some of them come from different places in different ages; we see: - marble, arrived not far from rome in the XVth century; - the paving comes from some hundred of kilometers, in the 50' of the last century; - three different types of light: the oldest one inside the basilica are halogen lamps, arrived sure from North Europe with african and european components I argue; the incandescent lamps of the street lamps, may be with the same origin of the previous; and the ones on the ledge of the Bernini's colonnade are led bulb, came from the far east; all of them were placed around the end of the 90s of the last century and the first decade of this century; - the most ancient piece af the plaza is the obelisk, came in Rome around two thousands years ago from the Upper Nile, Africa. May be in a thousand years we will have in our homes elements from the planets!
