Up to the midth of the 20th century in central europa single pigs were led by a rope, fixed on a hindleg. This technique can be proved back by pictures to antique. As shown by several illustrations this form was customary during Middle Ages and later.
直到20世纪中叶，在中欧，单头猪是用绳子拴在后腿上牵着的。这种技术通过图片可以追溯到古代。正如几幅插图所示，这种形式在中世纪及以后都很常见。
