During the Ming and Qing dynasties (1368-1911), the central government adopted the system of approving Tibetan chieftain to strengthen the control over Tibet. These methods made contribution to the development of the Tibetan society. So the Ming and Qing dynasties saw a great progress in the development of Thangka. Thangka of this period had three characteristics:
1. Thangka in larger number;
2. Different schools developed;
3. Appearance of many painting organizations.
Of the existing Thangkas, most were made during the Ming and Qing dynasties.
Content
The content of Thangka has various subjects such as historical events, personage biographies, religious doctrines, Tibetan natural conditions and social customs,folklores, mythical stories, images of great deities and Buddhas, and Jataka stories of the Buddha, etc., involving politics, economy, history, religion, literature and art, social life, Tibetan astrology, pharmacology, theology and many other respects. The structure of Tibet Thangka is precise, balanced, plumpy and changeful. The painting methods are mainly bright color and line drawing.
Thangka always has a theme of Buddhism, and the artists must follow the sacred laws for portraying gods and Buddhas. Passages from scriptures are written in vermilion on the back, and Thangka is always unsigned, so it is next to impossible to know the painter and the age of ancient Thangkas.
Process
Thangkas are usually placed upright in a rectangular shape while there are a few that deal with subjects of Mandala that are square. Cotton canvas and linen cloth are the common fabrics on which pictures are painted with mineral and organic pigments (important Thangkas use ground gold and gemstones as pigments). A typical Thangka has a printed or embroidered picture mounted on a piece of colorful silk. A wooden stick is attached on the side from the bottom to the top to make it easier to hang and roll up.
Painting a Thangka usually starts by stretching a piece of cotton cloth on a wooden frame along its sides. Then, a certain type of gesso is spread over both the front and back of the canvas to block the holes and then scraped off to produce smooth surfaces. Afterwards, some orienting lines are drawn to guide the sketching. By following a fixed proportion, images are then roughly drawn. The featured deity or saint occupies the center while other attendant deities or monks surround the central figure and along the border, and is comparatively smaller in size. Next is coloring. Painters apply pigments on the sketch. Black, green, red, yellow and white are the basic colors used in coloring. All the colors are mixed with animal glue and ox bile to keep them bright. Shading is then done to produce better pictorial effects. At the final stage, facial features and eyes are finished, which is sacredly done only after a ritual held on a fixed day. After detail finishes, the canvas is removed from the frame and mounted on a piece of brocaded silk. The wooden sticks are attached to the top and bottom of the silk. After a dust cover of gossamer silk is attached it is ready to be hung up.
