This pictograph depicts an unusual ancient Bon monument. Although it might generally be classed with the stupa it has no known modern counterpart. A narrow extension connects the wide base of the object with a half circular midsection. The top of the object is crowned by a prominent three-pronged structure reminiscent of the Bon charu chatri, the symbolic representation of the horns of the khyung flanking an upright sword. To the left of this enigmatic composition there is a counterclockwise yungdrung and what appears to be a five pointed star created using the same red ochre pigment. At the bottom of the image the vowel sign (kigu) of a Buddhist mantra painted in a darker ochre pigment is visible. This pictograph was probably executed during the early Buddhist period but we cannot rule out the possibility that it is older.
