notes
Revolt of the Fidenates, 425 BCE
Annō trecentēsimō et quīntō decimō ab urbe conditā: according to Livy (4.33.1–12) Fidenae was captured in 435 BCE and again, after revolting in 425 BCE. The former capture is generally rejected as a duplication. Lars Tolumnius, King of Veii, was killed by Aulus Cornelius Cossus, in 426 BCE or 425 BCE. Cossus, one of four military tribunes with consular power, nominated Mamercus Aemilius for the dictatorship and was then appointed magister equitum. It was in the following year that L. Quinctius Cincinnatus was appointed one of the four military tribunes. Eutropius’ chronological and other errors were probably caused by the telescoping of events, either by his source or by himself, and the fact that an officer named T. Quinctius played a major role in operations (Bird).
Auxilium hīs praestābant: hīs refers to the people of Fidenae.
(2) Quae ambae cīvitātēs tam vīcīnae urbī sunt: "both of these states are so close to the city" (Bird). quae is a connecting relative (AG 308.f), and tam signals the following two result clauses (AG 537).
