Here you see two imposing Bodhisattvas* standing with a monk. Even if they were not elevated, the highly polished, dark limestone lends a formal, almost unapproachable, quality to the images. The smooth, thin eyebrows, lowered eyelids, and sharp nose line further enhance the austerity. There is no opportunity for eye contact with a worshipper. The heavy jewelry is more to be examined than the faces. The monk is a Pratyeka-Buddha*, a mortal who lives apart from others and focuses on his personal attainment of enlightenment. Images intended to be seen and admired, but present themselves as distant from the world of man, are rare among Chinese Buddhist sculpture, but they are characteristic of Northern Qi* sculpture. The Buddhist cave site named Xiangtangshan*, meaning Mountains of the Echoing Halls, located in the Drum Cliffs of northeastern China, several hundred kilometers south of Beijing, is one of the largest repositories of Northern Qi sculpture. The images in the Penn Museum are among the best known examples of Xiangtangshan sculpture.
