1. Immediate Environs and the Campagna.
The vast Campagna di Roma, bounded on the N. by the Monte
Cimino, on the W. by the sea, on the S. by the Alban Mts., and on
the E. by the Apennine chain of the Sabina, affords an ample field
,for a number of the most interesting excursions. The mountains
with their picturesque outlines, and the wild and deserted plain,
covered in every direction with imposing ruins, chiefly of ancient
origin, present attractions of the highest order, to which years of
study might fitly be devoted.
