same circular form, erected by Numa Pompilius; the present edifice is far
too elegant for that age, but there is no record of its erection, but it
is known to have been repaired by Vespasian or Domitian after being
injured by Nero's fire. Its situation, near the Tiber, exposed it to
floods, from which we find it suffered, from Horace's lines--

Templaque Vestae."--Ode, lib. i. 2. 15.

This beautiful temple is still in good preservation. It is surrounded by
twenty columns of white marble, and the wall of the cell, or interior

columns), is also built of blocks of the same material, so nicely joined,
that it seems to be formed of one solid mass.
