This pattern was generated by putting several passive stains on a target and dragging the four
fingers of the right hand through the stains before they were dried.
Bloodletting scenes can be quite dynamic and wipe patterns are common. It may be possible to
determine the direction of travel of an object that created the wipe pattern.
