Points of Departure
I have decided to put together a critical essay regarding my interpretations and disputations of the contemporary existing texts on the Ichnographia. It will be called "Points of Departure"...
...this combined presentation technique may also follow Piranesi's methodology, thus offering the possibility of a further "re-enactment".
In thinking of the typologies... ...regard to Tafuri's comments of the Ichnographia being a sample book and something unknowable. ...the [scale] comparison between St. Peter's and the Bustum Hadriani is a perfect place to start, although I could also compare the Ichnographia plans to other ancient Roman plans, particularly the large baths. Such drawings would refute Tafuri's and Bloomer's statements regarding the smallness (and seemingly insignificantly treated Pantheon and tomb of Hadrian).
...Piranesi's cribbing of the Porticus Aemilia for the Septa Julia may actually represent Piranesi's scale for the entire Ichnographia. It could be that Piranesi very purposefully installed the Forma Urbis fragment of the Porticus Aemilia into the Ichnographia for the precise purpose of demonstrating more of the actual scale (and gigantism) of ancient Rome (--it is as if Piranesi is here illustrating his own quote about how one just has to look around at Rome and Hadrian's Villa to see the examples he emulates.) Piranesi was not being deceptive or misleading, nor was he acting out of ignorance of the fragment's true identity. Piranesi used the Porticus Aemilia as evidence and example.
