IMPALE, v.t. In popular usage to pierce with any weapon which remains
fixed in the wound. This, however, is inaccurate; to imaple is,
properly, to put to death by thrusting an upright sharp stake into the
body, the victim being left in a sitting position. This was a common
mode of punishment among many of the nations of antiquity, and is
still in high favor in China and other parts of Asia. Down to the
beginning of the fifteenth century it was widely employed in
"churching" heretics and schismatics. Wolecraft calls it the "stoole
of repentynge," and among the common people it was jocularly known as
"riding the one legged horse." Ludwig Salzmann informs us that in
Thibet impalement is considered the most appropriate punishment for
crimes against religion; and although in China it is sometimes awarded
for secular offences, it is most frequently adjudged in cases of
sacrilege. To the person in actual experience of impalement it must
be a matter of minor importance by what kind of civil or religious
dissent he was made acquainted with its discomforts; but doubtless he
would feel a certain satisfaction if able to contemplate himself in
the character of a weather-cock on the spire of the True Church.
