The time scale - Reigionare di Lombardia

I thought of writing one of my favourite photo that I took this year. This is the construction site of Regionale di Lombardia located close to Stazione di Milano Centrale. I stayed in a house of a friend of mine whose gallerist and art collector. I was so lucky to come across with this balcony to have an opportunity to take a photo that depicts series of different historical layers in single shot of an image.
The discovery of a layer of roman remain at 6ft under the post war housing blocks emphasizes the scale of approximately 2000 years which is represented by the thickness of soil accumulated over such period of time indicating the city's history. What really fascinates me is that, this mass body of soil is held by thin layer of concrete retaining wall that seems to be resisting very hard to protect remains but at the same time confirming the scale of the future development on site. It seems what humans are doing in adjacent is powerless but stretching the maximum effort possible to make this development possible. To my mind, these machineries are trying to eat up the house next to the construction site.
I love the situation when series of both physical and metaphorical layers coincides in a single shot of an image. The optical counterpart of an object can be the scale of time here.
