uries formed the new National Assembly. They mustered as an army
in the Campus Martius, or the Field of Mars, on the banks of the Tiber,
outside the city. They voted by Centuries, and were hence called the
_Comitia Centuriata_. Each Century counted as one vote, but did not
consist of the same number of men. On the contrary, in order to give the
preponderance to wealth, the first or richest class contained a far
greater number of Centuries than any of the other classes (as will be
seen from the table below), although they must at the same time have
included a much smaller number of men. The Equites and First Class alone
amounted to 100 Centuries, or more than half of the total number; so
that, if they agreed to vote the same way, they possessed at once an
absolute majority. An advantage was also given to age; for the Seniores,
though possessing an equal number of votes, must of course have been
very inferior in number to the Juniores.

Servius made the Comitia Centuriata the sovereign assembly of the
nation; and he accordingly transferred to it from the Comitia Curiata
the right of electing kings and the higher magistrates, of enacting and
repealing laws, and of deciding in cases of appeal from the sentence of
a judge. But he did not dare to abolish the old Patrician assembly, and
was even obliged to enact that no vote of the Comitia Centuriata should
be valid till it had received the sanction of the Comitia Curiata.

Thus, in consequence of the legislation, we shall find that Rome
subsequently possessed three sovereign assemblies: 1. The _Comitia
Centuriata_, consisting of both Patricians and Plebeians, and voting
according to Centuries; 2. The _Comitia Curiata_, consisting exclusively
of Patricians, and voting according to Curiae; 3. The _Comitia Tributa_,
exclusively of Plebeians, and voting according to Tribes.

II. The second great work of Servius was the extension of the
Pomoerium, or hallowed boundary of the city, and the completion of the
city by incorporating with it the Quirinal, Viminal, and Esquiline
Hills.[9] He surrounded the whole with a stone wall, called after him
the wall of Servius Tullius; and from the Porta Collina to the Esquiline
Gate, where the hills sloped gently to the plain, he constructed a
gigantic mound nearly a mile in length, and a moat 100 feet in breadth
and 30 in depth, from which the earth of the mound was dug. Rome thus
acquired a circumference of five miles, and this continued to be
