at City

But while neither an opulent urban middle class nor a strictly close
body of capitalists grew up in Rome, it was constantly acquiring more
and more the character of a great city. This is plainly indicated by
the increasing number of slaves crowded together in the capital (as
attested by the very serious slave conspiracy of 335), and still more
by the increasing multitude of freedmen, which was gradually becoming
inconvenient and dangerous, as we may safely infer from the
considerable tax imposed on manumissions in 397(37) and from the
limitation of the political rights of freedmen in 450.(38) For not
only was it implied in the circumstances that the great majority of
the persons manumitted had to devote themselves to trade or commerce,
but manumission itself among the Romans was, as we have already said,
less an act of liberality than an industrial speculation, the master
often finding it more for his interest to share the profits of the
trade or commerce of the freedman than to assert his title to
the whole proceeds of the labour of his slave. The increase of
manumissions must therefore have necessarily kept pace with the
increase of the commercial and industrial activity of the Romans.

Urban Police

A similar indication of the rising importance of urban life in Rome is
presented by the great development of the urban police. To this period
probably belong in great measure the enactments under which the
four aediles divided the city into four police districts, and made
provision for the discharge of their equally important and difficult
functions--for the efficient repair of the network of drains small and
large by which Rome was pervaded, as well as of the public buildings
and places; for the proper cleansing and paving of the streets; for
obviating the nuisances of ruinous buildings, dangerous animals, or
foul smells; for the removing of waggons from the highway except
during the hours of evening and night, and generally for the keeping
open of the communication; for the uninterrupted supply of the market
of the capital with good and cheap grain; for the destruction of
unwholesome articles, and the suppression of false weights and
measures; and for the special oversight of baths, taverns, and
houses of bad fame.

Building--
Impulse Given to It

In respect to buildings the regal period, particularly the epoch of
the great conquests, probably accomplished more than the first two
centuries of the re
