平安宮仁寿殿の建築についてその 2 : 平安時代初期の仁寿殿と里内裏における仁寿殿代 ON THE ARCHITECTURE OF JIJU-DEN IN THE HEIAN-DAIRI Part 2 : Jiju-den in the early Heian period
The architecture of Jiju-den in the Heian-Dairi rebuilt in the middle and late Heian period has been examined in Part 1. Part 2 examines Jiju-den in the early Heian period. 1) The plan of Jiju-den before the first destruction by the fire in 960 is supposed to have been well followed by those rebuilt in 961, 1100 and 1157. It may be said that from these we can know much about the original form of Jiju-den used as a building for the Emperor's private life, for Jiju-den in the late Heian period had extremely residential type of constructions in its interior space. 2) In Part 1 the present writer has shown the inferred plan of Jiju-den in the Heian-Dairi in the late Heian period. In that plan it is supposed that the central large room, 3 ken in keta-yuki and 4 ken in hari-yuki, in the main building followed the form of Yoru-no-otodo (a bed room for the emperor), contained by Jiju-den in the early Heian period, and that Hi-no-omashi (the emperor's seat in the daytime) would be placed in the next room on the east side to the central room, 2 ken in keta-yuki and 4 ken in hari-yuki, at that time. Of the three small rooms in the west part next to the central large room, the south one, 2 ken in keta-yuki and 1 ken in hari-yuki is presumed to have been Nenju-no-ma in which Sei-kannon, the principal image of Kannon-ku, was enshrined. The 2 ken square room on the north of it might probably have been used as Emperor's private room, or Tsune-no-gosho, like Fujitsubo-no-ue of Seiryo-den in the Heian-Dairi. Probably the Emperor would have come into this room when he was served with Kannon-ku. 3) It is supposed that at the beginning of the Heian period the Kita-magobisashi of Jiju-den would have been divided into a few small rooms which were used as Yu-dono (bathroom), Kawaya-dono (rest room), etc, but the Minami-magobisashi, the Higashi-bisashi and Nishi-bisashi would not have been divided into any small rooms.
