Tang Ka (Scroll Paintings) (唐卡)
Tang Ka are Tibetan Buddhist scroll paintings. Usually mounted on colorful silks, Tang Ka vary in styles and cover subjects in religion, medicine, astronomy, arts and architecture. They have become important historical materials for the study and research of Tibetan cultures. Potala Palace has more than 10,000 Tang Ka, which are housed in a 340-square-meter warehouse. On the 30th day of the second month of the Tibetan calendar, two tang ka are exhibited for millions of disciples to worship, a rather spectacular scene to witness.
