According to historical records, Silla produced six Buddhist statues during a period of fifteen years when it was under the rule of King Gyeongmun (r. 861-875). The number is quite significant considering that the kingdom's Buddhist statues carrying clear production dates are very rare. Interestingly, five of these are of Vairocana Buddha while the identity of the remaining one, an sixteen feet iron buddha enshrined in Allaksa Temple, is yet to be known. Unfortunately, three of the statues are not known of their whereabouts. Apart from them, there are currently several tens of Vairocana Buddha images which are believed to have been made during the period when Silla was ruled by King Gyeongmun and his predecessor King Heonan (r. 857-861). This study is focused on the unanswered question why Silla people of the period were so eagerly attracted to Vairocana Buddha image. The dominant view of the Buddhist art during the late Silla Period has been that the emergence of powerful regional warlords of the period weakened the power of the central government and grew into a new patron for the development of Buddhist art, helping it freed from the influence of the Silla capital Gyeongju and more focus on the diversity of regional traditions. The view, however, cannot explain the fact that the Buddhist artists of Silla under the King Gyeongmun's rule were more closely related with the royal family than regional warlords and interested in worshipping Vairocana Buddha image regardless of the schools they belonged to.
