Delphi
In 356 BC the Phocians under Philomelos captured and sacked Delphi, leading to the Third Sacred War (356–346 BC), which ended with the defeat of the former and the rise of Macedon under the reign of Philip II. This led to the Fourth Sacred War (339 BC), which culminated in the Battle of Chaeronea (338 BC) and the establishment of Macedonian rule over Greece.
In Delphi, Macedonian rule was superseded by the Aetolians in 279 BC, when a Gallic invasion was repelled, and by the Romans in 191 BC. The site was sacked by Lucius Cornelius Sulla in 86 BC, during the Mithridatic Wars, and by Nero in 66 AD. Although subsequent Roman emperors of the Flavian dynasty contributed towards to the restoration of the site, it gradually lost importance. In the course of the 3rd century mystery cults became more popular than the traditional Greek pantheon. Christianity, which started as yet one more mystery cult, soon gained ground, and this eventually resulted in the persecution of pagans in the late Roman Empire. The anti-pagan legislation of the Flavian dynasty deprived ancient sanctuaries of their assets. The emperor Julian attempted to reverse this religious climate, yet his "pagan revival" was particularly short-lived. When the doctor Oreibasius visited the oracle of Delphi, in order to question the fate of paganism,he received a pessimistic answer:
Third Mithridatic War
The period between the Second and Third wars of Rome and the Pontic Kingdom (81–75 BC) is discussed under the Kingdom of Pontus. There it can be seen how the long piracy wars were a development out of the First Mithridatic War and especially of the alliance between Mithridates VI and Sertorius, which in joining those two threats into a unity much larger than its parts had the serious potential of overturning Roman power. The immediate cause of the Third War was the bequest to Rome by King Nicomedes IV of Bithynia of his kingdom upon his death (74 BC).
