There were seven kings of the Romans, starting with Romulus, and [the kingship] ceased after a period of 244 years. From the capture of Troy until Romulus, 431 years elapsed. Altogether 675 years elapsed.
Dionysius of Halicarnassus gives a brief account of the dates of these kings, from Romulus to Tarquinius, around the time of the first Olympiad, as follows [Dion Hal 1.75] [g392].
[110] Dionysius of Halicarnassus Regarding the Kings in Rome after Romulus.
From Romulus, first ruler of the city, to the time of the expulsion of the kings two hundred and forty-four years elapsed. This is known both from the order of the kings' succession and the number of years each of them ruled. Following Romulus' death the city was kingless for one year. Then Numa Pompilius, who was chosen by the army, reigned for forty-three years.
After Numa, Tullus Hostilius ruled for thirty-three years [g393]. Ancus Marcius, his successor, ruled for twenty-four years. He was followed by Lucius Tarquinius, called Priscus, for thirty-eight years. Servius Tullius succeeded him, reigning for forty-four years. The murderer of Servius, the tyrant Lucius Tarquinius, extended his reign to the twenty-fifth year. Because of his contempt of justice, he was called Superbus. Romulus, the first ruler of the city, must have begun to rule in the first year of the seventh Olympiad [752 B.C.], when Charops at Athens was in the first year of his ten-year term as archon. [We calculate this] because the reigns of the kings [g394] amount to two hundred and forty-four years or sixty-one Olympiads. Thus the count of the [monarchs'] years requires this [determination of the placing of Romulus' rule]; and the number of years that each king reigned is known from writings. Such is the account given by those who lived before me and adopted by me concerning the time of the settlement of the city which now rules supreme.
This is Dionysius' account.
Now after the death of Tarquinius and the collapse of unified [royal] rule, the Romans no longer had kings. Instead, they appointed consuls [starting with] Brutus; then [they appointed] tribunes of the plebs; then dictators, who were orators; and then consuls again. I think it would be superfluous to list the magistrates of each year here, because there would be a huge mass of names. Moreover, if I described their achievements in detail, my account would become greatly enlarged and stray from its intended purpose. Consequently I think it is appropriate [g395] to leave these magistrates, and everything connected with them, to another chronicle: that is, the consuls who followed Tarquinius, the tribunes of the plebs and the dictators who governed the city of Rome during the years preceding the advent of Caesar. After these remarks, we will return to the reign of the first emperor. From the death of Tarquinius until the time of Julius Caesar, 115 Olympiads--the equivalent of 460 years--elapsed.
[111] Tarquinius died at the end of the 67th Olympiad [509 B.C.]. Caesar became emperor at the start of the 183rd Olympiad [48 B.C.]. Between these [two termini] an interval of 460 years exists. From the 7th Olympiad [752 B.C.], when the city of Rome was founded, [until the death of Tarquinius] 244 years elapsed. Thus, a total of 704 years--which is the equivalent of 176 Olympiads--elapsed from the foundation of Rome until the time of Julius Caesar.
This [schema] is confirmed by the chronicler Castor who writes as follows in a passage summarizing the [relevant] dates [g396]:
Castor on the Kingdom of the Romans.
We have listed the kings of the Romans one by one, beginning with Aeneas son of Anchises, when he became king of the Latins, and concluding with Amulius Silvius, who was killed by Romulus, the son of his niece Rhea. Now we will add Romulus and the others who ruled Rome after him up until Tarquinius Superbus, for a period of 244 years. After these kings, we will give a separate list of the consuls, starting from Lucius Junius Brutus, and ending with Marcus Valerius Messalla and Marcus Piso, who were consuls when Theophemus was archon at Athens [61 B.C.]. Altogether [they ruled] for 460 years.
That is what Castor says. Now it is appropriate for us to append a list of the emperors of the Romans, starting from Julius Caesar. We shall mention the consuls for each year, equating [these dates] with the Olympiads.
