The Dacians: Rome\'s Greatest Enemy?

[diegis]

<<Decius appeared in the world, an accursed wild beast, to afflict the Church—and who but a bad man would persecute religion? It seems as if he had been raised to sovereign eminence, at once to rage against God, and at once to fall; for, having undertaken an expedition against the Carpi, who had then possessed themselves of Dacia and Moesia, he was suddenly surrounded by the barbarians, and slain, together with great part of his army; nor could he be honoured with the rites of sepulture, but, stripped and naked, he lay to be devoured by wild beasts and birds, — a fit end for the enemy of God.>>

I thought Decius fell fighting Goths. And his body was never found.

Carpi was a Dacian tribe from the outside the borders of Roman province. Lactantius, a contemporan of those events, mentioned them as the ones who defeated and killed Decius.

I thought Lactantius was later, a contemporary of Diocletian.

Goths was "introduced" by Jordanes, 3 centuries after that event. And we know that he swaped/changed names and mixed the Dacians/Getae (Carpi being a Dacian tribe or tribal union) with the Goths all over his work, "Getica".
Lactantius as far as i know was a kid or a teenager when Decius was killed, and even if he started to write quite few years after that it is for sure a much better source then Jordanes
