It
was one of the characteristic peculiarities of this powerful sense of
citizenship, that it was, while not suppressed, yet compelled by the
rigid simplicity and equality that prevailed among the citizens to
remain locked up within the breast during life, and was only allowed
to find expression after death; but then it was displayed in the
funeral rites of the man of distinction so conspicuously and
intensely, that this ceremonial is better fitted than any other
phenomenon of Roman life to give to us who live in later times a
glimpse of that wonderful spirit of the Romans.
A Roman Funeral
It was a singular procession, at which the burgesses were invited to
be present by the summons of the public crier: "Yonder warrior is
dead; whoever can, let him come to escort Lucius Aemilius; he is borne
forth from his house." It was opened by bands of wailing women,
musicians, and dancers; one of the latter was dressed out and
furnished with a mask after the likeness of the deceased, and by
gesture doubtless and action recalled once more to the multitude the
appearance of the well-known man.
