Augustus - India connection
In Suetonius' Life of Caesar Augustus, there is mention of envoys from India coming to Rome to pay homage to Augustus Caesar. ...the Great Stupa in India (with gateway dating from the 1st century BC). ...the Indian structure is very much like the tomb of Augustus in Rome. ...a real connection between the tomb of Augustus and the Great Stupa is their almost unbelievable similarity in size and style.
the portrait of Piranesi
There is a portrait of Piranesi engraved by his son Francesco. The portrait is a profile set in a medalion, and the overall composition of the plate is in the Piranesi style. In the lower left corner, there is a stone fragment carved with plans, and it is indeed a fragment of the Ichnographia, specifically the Theater of Marcellus, the Minutia Vetus, and the Porticus Octavae. ...wonder if Francesco, or even Piranesi himself, saw the Ichnographia as Piranesi's greatest achievement. The four-sided Temple of Janus is also clearly delineated on the fragment.
...a case for the father-son theme that begins with Mars and Romulus (inversely God, the Father and His Son Jesus), and could include Augustus and Agrippa, and Trajan and Hadrian, and even Theodosius and Honorius.
