The “Arco di Portogallo” or “Arch of Portugal”, so called because it was located in the Corso in Rome near the residence of the Portugese ambassador, was demolished in 1662. I had never heard of it, I confess, until Anna Blennow tweeted an engraving by Piranesi. It stood near the Palazzo Fiano. It seems to have been a late edifice, perhaps of the time of Marcus Aurelius, perhaps later.
Let’s enjoy this image of another bit of vanished Rome.
A delightful illustrated article here about reconstructing the appearance of ancient Rome. One item in it caught my eye:
The article adds:
Among the most useful visual resources for studying the ancient city are the physical models which, since the eighteenth century, architects started to provide to help scholars and students better understand the ancient remains.
The pioneer was the famous cork-modeler, Antonio Chichi, who lived from 1743 to 1816. He created a set of 36 of the great sites of ancient Rome. Sold to Grand Tourists, they served as souvenirs but also as study aids (cf. Wilton and Bignamini 1996: 298) analogous to plaster casts of famous Greek and Roman statues, which, not coincidentally, as Giuseppe Pucci has shown, also came into vogue at this time (Pucci 1997).
As can be seen in the case of the model of the Arch of Titus (fig. 9), Chichi’s reproductions were state models, not reconstructions: that is, they showed the current condition of the monument.
In the example at hand, we thus see the arch still embedded within the Frangipane tower before Valadier’s restoration of the early nineteenth century.
