Herennius Etruscus and father
Herennius Etruscus was the elder son of Emperor Decius and ruled from May to June 251 CE. From the beginning of the reign of Herennius, the gothic tribes (under the so-called Kniva) crossed the Danube and looted Moesia and Dacia. An expedition of 20,000 Romans was organized against the invaders, in which father and son took part.
