Juvenal speaks of it.

Overthrown by earthquake, erected again at once, twice burned and
immediately rebuilt, five times the seat of Councils of the Church,
enlarged even in our day at enormous cost, it seems destined to stand on
the same spot for ages, and to perpetuate the memory of the Laterans to
all time, playing monument to an obscure family of rich citizens, whose
name should have been almost lost, but can never be forgotten now.

Constantine, sentimental before he was great, and great before he was a
Christian, gave the house of the Roman gentleman to Pope Sylvester. He
bought it, or it fell to the crown at the extinction of the family, for
he was not the man to confiscate property for a whim; and within the
palace he made a church, which was called by more than one name, till

era, the whole Roman people, without sanction of the Emperor and without
precedent, chose John the Thirteenth to be their Pope. The Regions with

their acclamation. Then came their disappointment, then their anger.
Pope John, strong, high-handed, a man of order in days of chaos, ruled
from the Lateran for one short year, with such wisdom as he possessed,
such law as he chanced to have learnt, and all the strength he had.
Neither Barons nor people wanted justice, much less learning. The Latin
chronicle is brief: 'At that time, Count Roffredo and Peter the
Prefect,'--he was the Prior of the Regions' Captains,--'with certain
other Romans, seized Pope John, and first threw him into the Castle of
Sant' Angelo, but at las
