KYOTO–Byodo-in temple in Uji, Kyoto Prefecture, has used computer graphics to recreate the colorful interior of the Hoo-do (Phoenix Hall) as it was believed to look at the time of the temple’s founding in 1053.
The temple is part of a cluster of old temples and shrines in Kyoto and Shiga prefectures collectively designated a UNESCO World Heritage Site. An exterior view of the Hoo-do appears on Japan’s 10 yen coin.
The CG images, which show colorful patterns on pillars, beams and a shumidan altar for enshrining Buddhist statues, are on display at the Hoshokan museum on the temple grounds. The original colors of the hall interior have faded over the centuries.
“[The CG images] evoke a peaceful sea bottom,” said Monsho Kamii, 47, chief priest of the temple.
According to the temple, particles of lapis lazuli, a blue mineral that was precious when the temple was built, were discovered around the altar. Therefore, the altar platform is colored in vivid blue in the 3-D images. Its sides are decorated with elegant mother-of-pearl work in the reproduced images.
Experts determined the types of paints originally applied to the pillars and beams and reproduced color sketches of the interior.
The wall color was determined to be blue based on the color coordination of the interior, according to the temple.
Two CG images and selections from a group of 13 color sketches will be displayed alternately until Aug. 6.

Interesting stuff. I was just at the replica Byôdô-in here in Hawaii a few weeks ago, and thinking about how the replica may differ from the real one (in brighter, fresher paint, etc.), and how the real one may differ from how it looked in the past. Perfect timing, really, for me, for this to come out, given that I was thinking about it.
These images are on display at the temple?
Yes, they are on display at the Hoshokan Museum on the temple grounds (the news article says).
Thanks for writing in. Looking forward to future stuff you’ll be writing, I’d sure love to be doing a course on art history like yourself. Right now, I’m looking at art of the Silk Route and from the Kofun era to Nara era. Maybe in my former life, I was a curator or chronicler…
