This fountain is
situated on the Janicule Hill, from which you have perhaps the best view of
Rome; as it re-unites more than any other position, at one coup d'oeil,
both the modern and debris of the ancient city, without the view of the one
interfering with or being intercepted by the other. From here you can
distinguish rums of triumphal arches, broken columns, aqueducts, etc., as
far as the eye can reach. It demonstrates what an immense extent of ground
ancient Rome must have covered. Near the fountain is the church where St
Peter is said to have suffered martyrdom with his head downwards.
The Column of Trajan is near the fountain Trevi, and it stands in an
inclosure, the pavement of which is seven feet lower than the piazza on
which it stands. The inclosure is walled round. Had not this excavation
been made, one third of the column (lower part) would not be seen. The
Piazza, on which this column stands is called Il foro Trajano. The
column represents Trajan's triumphs over the Daci, Quadi and Marcomanni,
and is the model from whence Napoleon's column of the Grand Army in the
Place Vendome at Paris is taken. A statue of St Peter stands on this
column.
The Column of Antoninus stands on the Piazza Colonna; on it are
sculptured the victories gained by that Emperor.
