Bouvier's Law Dictionary, Revised 6th Ed (1856):

RAPINE, crim. law. This is almost indistinguishable from robbery. (q.v.) It
is the felonious taking of another man's personal property, openly and by
violence, against his will. The civilians define rapine to be the taking
with violence, the movable property of another, with the fraudulent intent
to appropriate it to one's own USC. Lec. El. Dr. Rom. Sec. 1071.
