to a great
distance, and though more rudely excavated than most of those nearer the
city, as if intended for the burial-places of a poorer population, they
are of peculiar interest because many of their graves remain in their
original state, and here and there, in the mortar that fastens their
tiled fronts, portions of the vessel of glass or pottery that held the
collected blood of the martyr laid within are still undisturbed. No
pictures of any size or beauty adorn the uneven walls, and no chapels
are hollowed out within them. Most of the few inscriptions are scratched
upon the mortar,--_Spiritus tuus in bono quiescat_,--but now and then a bit
of marble, once used for a heathen inscription, bears on its other side some
Christian words. None of the inscriptions within the church which bear
a date are later than the end of the fifth century, and it seems likely
that shortly after this time this church of the Campagna was deserted,
and its roof falling in, it was soon concealed under a mass of rubbish
and of earth, and the grass closed it with its soft and growing
protection.

During two years, the uncovered church, with its broken pillars, its
cracked altar, its imperfect mosaics, its worn pavement, remained open
to the sky, in the midst of solitude. But how could anything with such
simple and solemn associations long escape desecration at Rome? How
could such an opportunity for _restoration_ be passed over? How could so
sacred and venerable a locality be protected from modern superstition
and ecclesiastical zeal? In the spring of 1837, preparations were being
made for building upon the ground, and a Carthusian convent, it was
said, was to be erected, which would enclose within its lifeless walls
the remains of the ancient church. Once more, then, it is to be shut
out of the sky; and now it is not Nature that asserts her predominance,
protecting while she conceals, and throwing her mantle over the martyrs'
graves to keep them from sacrilege,--but she is driven away by the
builders of the papal court, and all precious old associations are
incongruous with those of modern Roman architecture and Roman conventual
discipline.

One morning, in the spring of 1855, shortly after the discovery had been
made, the Pope went out to visit the Church of St. Alexander. On his
return, he stopped to rest in the unoccupied convent adjoining the
Church of St. Agnes. Here there was a considerable assemblage of those
who had accompanied h
