The feast of All Saints is very ancient in the Oriental
churches, and is assigned to the Octave of Pentecost, the
Anglican Trinity Sunday. See Neale, Eastern Church, vol. ii. pp.
734, 753. In the West it was instituted when Boniface III. (who
accepted from the Emperor Phocas the title of "Universal
Bishop," a.d. 607) turned the Pantheon into a church, and with a
sort of practical epigram called it the church of" All the
Saints." It was a local festival until the ninth century, when
the Emperor Louis the Pious introduced it into France and
Germany. Thence it came to England. It falls on the 1st of
November. The gates of the church at Rome are the same which
once opened for the worship of "all the gods." They are of
massive bronze, and are among the most interesting of the
antiquities of the city. The modern gates of St. Peter's, at
Rome, are offensive copies of heathen mythology; and among the
subjects there represented, is the shameful tale of Leda,-a
symbol of the taste of Leo X.
