Abstract

This thesis classified the stylobate part of stone pagoda of Unified Silla, separated the period and identified evolution, and reviewed the stone pagoda which became subject to controversy of chronology. Stone pagoda of typical form of Unified Silla can be classified into about 5 stages by grouping the classification depending on features. The 1st stage (unification of three nations ~end of the 7th century) is the period when the stone pagoda of typical form appeared. The 2nd stage(end of the 7th century~ early 8th century) is the period when initial stone pagoda had settled down as the most structurally stable stone pagoda through change in connection structure of the upper layer stylobate from them of the 1st stage. The 3rd stage(middle of the 8th century~ early 9th century) is the period when there were 2 types such as existing type of stone pagoda and totally new type of stone pagoda. Accordingly, 3rd stage can be regarded as the most important period in terms of evolution process of stone pagoda of typical form of Unified Silla when there coexisted change to new type and establishment of old type. What most attracts our attention as change of new form was the change in connection structure of the lower stylobate and along with this, new type of flat stone appeared and change of strut post was identified. The 4th stage (early 9 ~ late 9th century) is the period when only some structures were standardized and prevailed throughout the country out of several new types of connection structure that appeared in the 3rd stage. In terms of trimming stone on the lower layer stylobate, new types appeared which didn’t appear in the 1st stage~3rd stage. 5th stage(end of 9th century~935) is the period when the type and form showed retrogressive change and modeling of stone pagoda of Unified Silla was stuck in a rut. Connection structure of the 4th stage was used as it was or showed the aspect of schematization into the irregular form. and It means everything that some of the type of the stone pagoda in this term lead to them of Goryeo Dynasty. This study examined 5 story stone pagoda at Nawonrisa temple site, 5 story stone pagoda at Janghangrisa temple site and 3 story stone pagoda at Changlimsa temple site, which subject to controversy of chronology, and the stone pagodas were built in 8th century in through separation of period and type of stone pagoda through such Stylobate part structure. As a result of this examination, 5 story stone pagoda at Nawonri temple site was built in the middle of the 8th Century(740~760), not in the early 8th century. 5 story stone pagoda at Janghangri temple site was built the late 8th Century, not in the early 8th century. 3 story stone pagoda at Changlim temple site was built form the late 8th Century to the end of 8th Century, later than Janghangri' stone pagoda and the stone pagodas were built in 8th Centrury were chronicled the order of the stone pagodas, Guwhang-dong's 3 story stone pagoda(692~706), Cheongun-dong's 3 story stone pagoda(about 740), Nawonri's 5 story stone pagoda(about 740~760), Wonwon temple site's 3 story stone pagoda(about 760)․Galhang temple site's 3 story stone pagoda(758), west stone pagoda at Bulguk temple(about 760), Janghangri temple site's stone pagoda(about 760~780), Changlim temple site's 3 story stone pagoda(about 780).
