on an ancient Dacian pot bearing the words “Decebalus per Scorilo”. Though far from certain, this has also been translated as "Decebalus son of Scorilo". If so, this might mean that Decebalus was the son of Scorilo, with Duras possibly being either an older son or a brother of Scorilo. A Dacian king (dux Dacorum) called Scorilo is also mentioned by Frontinus, who says he was in power during a period of turmoil in Rome. From this evidence and references to Dacian kings elsewhere, it is suggested that Scorilo probably ruled from the 30s or 40s AD through to 69–70. The Dacians regularly raided into Roman territory in Moesia. The emperors Tiberius and Caligula solved this problem by paying protection money to the Dacians in the form of annual subsidies. This policy appears to have coincided with the reign of King Scorilo. Scorilo's brother was apparently held captive for a period in Rome, but was released in exchange for a promise that the Dacians would not intervene in Rome's volatile power-politics. During the reign of Emperor Nero, troops were withdrawn from the Dacian border, leaving the empire vulnerable. When Nero was overthrown in 69, the empire was plunged into turmoil in the Year of Four Emperors. The Dacians appear to have tried to take advantage of the situation to launch an invasion of Moesia in alliance with the Sarmatian Roxolani. The invasion was ill-timed. Licinius Mucianus, a supporter of Vespasian, was advancing with an army through Moesia towards Rome to overthrow Vitellius. The Dacians unexpectedly encountered his forces and were pushed back, suffering a major defeat. Scorilo appears to have died around this time, perhaps during the campaign. King Duras ruled between the years AD 69 and 87, during the time that Domitian ruled the Roman Empire. He was one of a series of rulers following the Great King Burebista. Duras' immediate successor was Decebalus. Duras may be identical to the "Diurpaneus" (or "Dorpaneus") identified in Roman sources as the Dacian leader who, in the winter of 85, ravaged the southern banks of the Danube, which the Romans defended for many years. Many authors refer to him as "Duras-Diurpaneus". Other scholars argue that Duras and Diurpaneus are different individuals, or that Diurpaneus is identical to Decebalus. The Roman governor of Moesia, Oppius Sabinus, raised an army and went to war with the Dacians following the Dacian (Getae) raids into Roman
