Anno urbis... sexto: Eutropius is (again) a little off again in his dating. This event occured in 75/4 BCE.
When did Eutropius say the event happened?
Bithyniae:
The ancient kingdom of
Bithynia is located
here in modern day Turkey, right next to the Bosphorus Strait,
which leads directly into the Black Sea.
fecit heredem:
When Nicomedes passed away, he left the kingdom of Bithynia
in the hands of the Roman people, rather than leaving it to his heir.
The Roman Senate accepted this gift with the knowledge that this might
upset the powers in the East.
