『扶桑略記』推古天皇四年（596）条：

冬十一月､法興寺を造り終わった｡天皇は无遮会を設け､これを供養された〔今の元興寺がこれである〕｡
その時､花蓋のような形の一つの紫雲があって､上天から降りてくると､塔上を円く覆った｡
また仏堂を覆い､変じて五色となり､あるいは龍鳳となり､あるいは人畜のようであったが､
やや久しくして西方に向かって去ったので､合掌して見送った｡
（太子は）左右の者に語って､
｢この寺に天が感応されたので､この祥瑞があったのです｡
ただし三百年後には霜露が訪れた者の衣を濡らし､五百年後には塔殿は廃亡しているでしょう｣
と仰せになった｡

左右の者：｢･･･このような素晴らしい堂塔が廃亡してしまうというのですか！？｣
太子：｢世間虚仮｡この世のすべてはかりそめごとです｡いくら寺とはいえ､その理からは逃れられません｣
左右の者：｢そんな〜･･･｣
太子：（そんなことはどうでも良いのです｡あの者の衣裳､無袖腋見せ･･･なんという新しさ！これは流行る･･･！）

※神霊廟とどいたｰ
※そして浮かんだ妄想を絵にしてみた
※ぬえちゃんが腋なのはなんとなくです
※そこから発展して神子さまはまだ袖つき､となりました
※『日本書紀』の推古天皇二十七年（619）にみえる人魚？記事もこのﾊﾟﾀｰﾝでいけるかも
※この絵とは関係ないけど妖夢かわいい

From the "Fourth year of the reign of Empress Suiko (596 A.D.)" section of "Fusou-Ryakuki":http://ja.wikipedia.org/wiki/%E6%89%B6%E6%A1%91%E7%95%A5%E8%A8%98 [a history written by the monk Kouen in the Heian period]

In November that winter, the construction of "Houkou-ji Temple":http://en.wikipedia.org/wiki/Asuka-dera was completed. The empress held a religious ceremony for the occasion called mushae (literally, "Unlimited Alms Assembly"). [This is the current "Gangou-ji Temple]":http://en.wikipedia.org/wiki/Gang%C5%8D-ji

At that time there were purple clouds in the shape of flower petals(tepals), which came down from the heavens and surrounded the pagoda in a ring.
They then covered the temple, became multi-colored, taking a shape like a dragon or phoenix, then a shape like a man or a beast, and after some time passed, they headed to the west and departed, while everyone clasped their hands in prayer and watched them go.
(Prince Shotoku) [Note: the subject is omitted from this part of the text.] spoke and declared to the people around him,
"Heaven has given a response to this temple, and it is a good omen. However, three hundred years from now, frost and dew [Note: that expression is used as a metaphor for the transience of human life.] will wet the clothes of those who visit, and five hundred years from now, the pagoda and temple buildings will be abandoned in ruins."

Prince's attendants: "...I've never seen such a majestic tower and temple... and the buildings will be ABANDONED IN RUINS!?"
Prince: "‘The things of this world are all transient illusions’, it is an inevitable fate. Even Buddhist temples are no exception.
Attendants: "Oh that's terrible!"
Prince: (That's not the point... Her sleeveless clothing, showing armpits... How outrageous! It will certainly become popular...!)

• The game I ordered, Ten Desires, arrived today.
• And I made my imagination into a piece of art.
• I made Nue wear sleeveless for no particular reason. And it leads to Miko wearing old sleeved clothes.
• Probably I can use the same method on a "merman" (?) in the 27th year of the reign of Empress Suiko (619 A.D.) section of "Nihon Shoki.":https://en.wikipedia.org/wiki/Nihon_Shoki [Note: See post #1000168]
