Furka (Lat. furca) - a wooden crosshair used by Roman legionnaires to carry their belongings on long military campaigns. Probably, for greater strength of the structure, two sticks were made depressions in the place of their connection, and then tied together. Perhaps a pilum was also attached to the long part of the furka .
