Cao Ba was a legendary artist who lived during the Tang Dynasty.

He began studying Chinese calligraphy and painting at a young age and later became renowned for his extraordinary paintings of people and horses.

In 718 AD, Emperor Xuanzong invited Cao Ba to paint at the imperial court.

The emperor was deeply impressed by Cao's exceptional skills and, after watching him work, appointed him as the official court painter.

Near the imperial palace stood a magnificent pavilion famous for its beautiful frescoes depicting the twenty-four heroes who had helped establish the Tang Dynasty.

However, after decades of exposure to the elements, the plaster had begun to crack and peel, and the once-brilliant colors had faded.

One day, Emperor Xuanzong ordered Cao Ba to restore the murals in the pavilion.

With thorough preparation, Cao Ba finally began the important royal commission.

When the work was completed, the newly restored paintings caused a sensation throughout the court.

Several years later, Du Fu, one of the greatest poets of the Tang Dynasty, wrote a poem praising Cao's artistic achievements.
