PORTICUS MILIARIA
built by Nero within the precincts of the domus Aurea
(Suet. Nero 31:
tanta laxitas ut porticus triplices miliarias haberet).
This reading seems to oblige us to suppose that the porticus was triple
and a mile long, or that there were three porticoes, in each of which a walk
of a mile could be taken (see
PORTICUS TRIUMPHI).
