Tibetans "barbarians", and announced the marriage of one of his daughters to the king of Duyu, a Hun. This infuriated Gampo, who mounted attacks on tribal areas affiliated with the Tang dynasty and then attacked the Tang city of Songzhou. Telling the emperor that he would escalate his aggression unless the emperor agreed to his proposal, Gampo sent a conciliatory gift of a gold-studded "suit of armour" with another request for marriage. Taizong conceded, giving Princess Wencheng to the Tibetan king. When Wencheng went to Tibet in 640 as the Chinese wife of the king (known as Gyasa in Tibet), she brought an image of Sakyamuni Buddha as a young prince. The image was deified in a temple originally named Trulnang, which became the Jokhang. The temple became the holiest shrine in Tibet and the image, known as Jowo Rinpoche, has become the country's most-revered statue. The oldest part of the temple was built in 652 by Songtsen Gampo. To find a location for the temple, the king reportedly tossed his hat (a ring in another version) ahead of him with a promise to build a temple where the hat landed. It landed in a lake, where a white stupa (memorial monument) suddenly emerged over which the temple was built. In another version of the legend, Queen Bhrikuti founded the temple to install the statue she had brought and Queen Wencheng selected the site according to Chinese geomancy and feng shui. The lake was filled, leaving a small pond now visible as a well fed by the ancient lake, and a temple was built on the filled area. Over the next nine centuries, the temple was enlarged; its last renovation was carried out in 1610 by the Fifth Dalai Lama. The temple's design and construction are attributed to Nepalese craftsmen. After Songtsen Gampo's death, Queen Wencheng reportedly moved the statue of Jowo from the Ramoche temple to the Jokhang temple to secure it from Chinese attack. The part of the temple known as the Chapel was the hiding place of the Jowo Sakyamuni. During the reign of King Tresang Detsan from 755 to 797, Buddhists were persecuted because the king's minister, Marshang Zongbagyi (a devotee of Bon), was hostile to Buddhism. During this time the image of Akshobya Buddha in the Jokhang temple was hidden underground, reportedly 200 people failed to locate it. The images in the Jokhang and Ramoche
