Abstract
In this paper will be added other proofs to support the former conclusion that the lean-to-roofs of the extant east pagoda at Yabushiji are made from the old materials of the original pagoda in the Fujiwara capital. The main proofs are as follows : 1. The carpenter's rule as calculated from the bays of the first story lean-to-roof of the extant east pagoda, is different from that obtained from the inner core of the building, but is the same as that discovered from the foundation stones at the site of the original east pagoda in the old Fujiwara capital. 2. It should be considered that it was when the pagoda was built that the outer pillars of the core building of the extant east pagoda were placed 1 SUN (about 1/10 foot) beyond the first planned position. We can conclude it was necessary to adjust the new core building to the old lean-to-roofs moved from the original Yakushiji. First, the outer pillars of the core building at the original Yakushiji leaned inward at the top, but it becomes obvious that the outer pillars at the Heijo Yakushiji had no inward slope from its first planning. Secondly, the carpenter's rule of the original pagoda was a little longer than that of the core building of the extant east pagoda at the Heijo Yakushiji. 3. The rafters of the first story lean-to-roof bear marks which are considered to suggest they had been used in the original pagoda in the Fujiwara capital. In reference to 1, that is, that the carpenter's rule of the core building of the extant east pagoda is different from that obtained from the foundation stones at the east pagoda site in the old Fujiwara capital, is at the same time another proof for the former conclusion that the inner core of the extant east pagoda was constructed newly in the Heijo capital. Those old materials probably came from the original east pagoda at Fujiwara, which had been dismantled and its core building was set up as the west pagoda at the new site in the Heijo capital. Consequently, it can be presumed that in this west pagoda the core building was formed of the old materials but attached to it was lean-to-roofs made of new materials. This paper also clarifies much regarding the technique of the leaning-inward of walls and pillars.
