A Dacian king (dux Dacorum) called Scorylo is also mentioned by Frontinus, who says he was in power during a period of turmoil in Rome.

[1] The Roman historian Jordanes lists a series of Dacian-Getic kings before Decebalus, placing a ruler called "Coryllus" between Comosicus and Dorpaneus.

[2] Modern scholars sometimes equate this otherwise unknown successor Dorpaneus with the king Duras attested in other sources.

It has been further speculated that this ruler is also named on an ancient Dacian pot bearing the latin stamp inscription “Decebalus per Scorilo”.

The emperors Tiberius and Caligula solved this problem by paying protection money to the Dacians in the form of annual subsidies.
