and striking ceremony on the Campus Martius after the census had been
finished. It was called the Lustration or _Suovetaurilia_. The first
name originated from the fact that the ceremony was a purification of
the people by water, and the second because the sacrifice on the
occasion consisted of a pig, a sheep, and an ox, the Latin names of
which were _sus_, _ovis_, and _taurus_, these being run together in a

celebration. Three times were the pig, the sheep, and the bull carried

the burning of incense, and the sounding of trumpets, the libation was
poured forth, and the inoffensive beasts were sacrificed for the
purification of the people. Once every five years the inhabitants were
thus counted, and once in five years were they also purified, and in
this way it came to pass that that period was known as a _lustrum_.

Uneasy lies the head that wears a crown, says the proverb, and it was
true in the case of Servius, for he could never forget that the people
had not voted in his favor. For this reason he divided among them the
lands that he had taken from the enemies he had defeated, and then,
supposing that he had obtained their good-will, he called upon them to
vote whether they chose and ordered that he should be king. When the
votes came to be counted, Servius found that he had been chosen with a
unanimity that had not been manifested before in the selection of a
