Satan just might be in Rome these days, but from Revelation chapter 2, to the church in Pergamos...”where Satan’s throne is”...Actually was a throne to Zeus or temple of Isis in Pergamos. Now it is in a museum in Berlin.
But the sword that pierced Yeshua is still in Salzburg, Austria.
Pergamos/Bergama was a "neokoros". Looks like it was eager to guzzle the Imperial Kool-aid:
In the Roman period, Pergamum became the capital of Asia, as the first city to make an alliance with Rome. Ephesus became the capital of the province, but scholars have argued that this city remained the focal point of the worship of the Roman Emperors. The city lost its great library to Alexandria when Mark Antony gave it to Cleopatra. The famous physician Galen, who served the emperors Marcus Aurelius, Commodus, and Septimius Severus, was born here in 129 CE.
The religious life of Pergamum has been the subject of much research by scholars and historians. Three specific “threads” appear to be visible. First, the association with the worship of snakes and the handling of reptiles in antiquity appears valid. Other early signs of the worship of Dionysus, the god of vegetation also appears to be well accepted. Later, worship of Asklepios (Roman Aesculapius) the god of healing emerged. The serpent became the emblem of Asklepios. “A Pergamene coin shows the emperor Caracalla standing spear in hand before a great serpent twined around a bending sapling…. Christians must thus have found the cult of the god of healing, and his serpent – infested temple, peculiarly revolting” (Blaiklock, Ibid.). The altar of Zeus built by Eumenes II to commemorate the victory of Attalus I over the Gallic invaders had striking pagan scenes on the frieze. The gods of Olympus were represented as giants with serpent – like tails. Zeus was called “saviour”.
The second association was dominant in the Hellenistic kingdom. This included the worship of Zeus and the goddess Athene. Finally, the Imperial Cult flourished in the city, making it a “neokoros” or temple guardian for the Roman Imperial cult. The first temple in Asia was erected to Augustus in 29BCE. Other temples were later erected to honor Trajan and Caracalla. It was Emperor Domitian who made these temples a litmus test for civic loyalty.
