9. TRIUMVIRI NOCTURNI were magistrates elected annually, whose chief
duty it was to prevent fires by night, and for this purpose they had
to go round the city during the night (_vigilias circumire_). If they
neglected their duty they appear to have been accused before the
people by the tribunes of the plebs. The time at which this office
was instituted is unknown, but it must have been previously to the
year B.C. 304. Augustus transferred their duties to the Praefectus
Vigilum. [PRAEFECTUS VIGILUM.]
10. TRIUMVIRI REFICIENDIS AEDIBUS, extraordinary officers elected
in the Comitia Tributa in the time of the second Punic war, were
appointed for the purpose of repairing and rebuilding certain temples.
11. TRIUMVIRI REIPUBLICAE CONSTITUENDAE. When the supreme power
was shared between Caesar (Octavianus), Antony, and Lepidus, they
administered the affairs of the state under the title of _Triumviri
Reipublicae Constituendae_. This office was conferred upon them in
B.C. 43, for five years; and on the expiration of the term, in B.C.
38, was conferred upon them again, in B.C. 37, for five years more.
The coalition between Julius Caesar, Pompey, and Crassus, in B.C. 60,
is usually called the first triumvirate, and that between Octavianus,
Antony, and Lepidus, the second; but it must be borne in mind that
the former never bore the title of triumviri, nor were invested with
any office under that name, whereas the latter were recognised as
regular magistrates under the above-mentioned title.
12. TRIUMVIRI SACRIS CONQUIRENDIS DONISQUE PERSIGNANDIS,
extraordinary officers elected in the Comitia Tributa in the time of
the second Punic war, seem to have had to take care that all property
given or consecrated to the gods was applied to that purpose.
13. TRIUMVIRI SENATUS LEGENDI were magistrates appointed by Augustus
to admit persons into the senate. This was previously the duty of the
censors.
TRŎCHUS (τροχός), a hoop. The Greek hoop was a bronze ring, and had
sometimes bells attached to it. It was impelled by means of a hook
with a wooden handle, called _clavis_, and ἐλατήρ. From the Greeks
this custom passed to the Romans, who consequently adopted the Greek
term. The following woodcuts from gems exhibit naked youths trundling
the hoop by means of the hook or key. They are accompanied by the jar
of oil and the laurel branch, the signs of effort and of victory.
