The Palatine hill was under the Republic only a simple residential area for high ranking people, Cicero, Mark-Antony, Marcus Agrippa, and of course Octavian, the future Augustus-Cæsar. Under the Empire, it became richer with vast palaces that can be simply divided as follows : on the left side of the picture, the Palace of Tiberius, in the centre, the Domus Flavia and the Domus Augustana that form together an immense square structure, on the top right the Stadium and the Palace of Septimius-Severus. This far view lets better understand that the palaces of the Palatine had become a colossal structure, where the bulding were embedded in eachother, giving the illusion that the whole construction had been planned.

A closer view shows the central part of the palace, the Domus Flavia, with the great peristyle and its basin. Next to the palace you notice the temples built on the Palatine.

The Septizodium was built under Septimius-Severus, who wanted to complete the magnificent aspect of the palaces. It was called Septizodium because it represented the seven planets that were then known. No doubt that the visitors who came to Rome by the Via Appia, have certainly had a grandiose impression as the Septizodium appeared by the corner of the Imperial Palaces and the Circus Maximus. Jacques Plassardsuggests a visit in synthetic picture.
