兎の餅つき

月の表面には、海と呼ばれる暗い部分が広がっている。溶岩が冷えて固まった平原で、模様そのものに意味はない。だが人はそこに、必ず何かの姿を見てしまう。

日本と韓国では、この模様は餅をつく兎として語られてきた。仏教説話に由来する話で、老人に身を捧げた兎を神が哀れみ、月に甦らせたのだという。中国では同じ兎が、臼で薬草を挽いているとされる。同じ兎という主題でも、何をしているかは土地によって変わる。

モンゴルでは犬に見立てられる。インドネシアでは編み物をする女性、ベトナムでは木の下で休む男性だという。インドではワニ、南アメリカ、とりわけアマゾン川流域のブラジルでもワニに見立てられる。力を持ち、恐れられる存在としての川の生き物が、月にもそのまま投影されている。

ヨーロッパに目を移すと、北ヨーロッパでは本を読む老婆、南ヨーロッパと中国の一部では大きな鋏を持つ蟹、東ヨーロッパでは女性の横顔、ドイツでは薪を担ぐ男とされる。アラビアでは吠える獅子、カナダの先住民の伝承ではバケツを運ぶ少女が語られる。ニュージーランドのマオリの間では、月の神を怒らせて月に連れ去られたロナという女性の姿だとされ、ポリネシアやメラネシアの多くの地域では、三つの石の上で火を使って料理をする人の姿として語り継がれている。

地球から見える月の面は常に同じである。したがって、これらはすべて同一の模様に対する解釈にすぎない。兎も、蟹も、老婆も、ワニも、網膜に届く光の配置としては同じものを指している。違うのは、見る側がどのような物語の型をあらかじめ持っているかということだけだ。兎のいない土地では兎は見えず、ワニの棲む川のそばでは月にもワニが棲みつく。土地の生態系、伝承、生活の記憶が、そのまま参照枠となって像を規定している。

これは、対象そのものの物理的な差異がどれほど小さくても、見る側の参照枠が異なれば立ち上がる像はまったく別のものになるという事態の、もっとも日常に定着した例だと言える。月の模様という一つの不変の実体に対して、無数の像が並列に存在し、しかもそのどれもが、それぞれの土地では自明なものとして受け取られている。像の複数性は誤認の結果ではなく、参照枠の複数性がそのまま反映されたものである。

満月を見上げるとき、そこに映るのは月の地形ではなく、見る者が属する文化の型そのものだと言ってもよい。

 

The Rabbit Making Mochi

The Moon's surface is covered with vast dark areas known as maria. They are plains formed by ancient lava that cooled and hardened, and the patterns themselves have no inherent meaning. Yet human beings inevitably see something in them.

In Japan and Korea, these patterns have traditionally been seen as a rabbit pounding mochi, Japanese rice cakes. The image comes from a Buddhist tale in which a rabbit sacrifices itself to an old man, and a god, moved by its selflessness, restores the rabbit to life on the Moon. In China, the same rabbit is said to be pounding medicinal herbs in a mortar. Even when the subject is the same rabbit, what it is doing changes from one place to another.

In Mongolia, the pattern is seen as a dog. In Indonesia, it is said to resemble a woman knitting, while in Vietnam it is seen as a man resting beneath a tree. In India, as well as in South America—particularly in the Amazon region of Brazil—it is interpreted as a crocodile. The river creature, powerful and feared, seems to have been projected onto the Moon itself.

Turning to Europe, Northern Europeans have seen an old woman reading a book, while in Southern Europe and parts of China the shape has been interpreted as a crab holding large pincers. In Eastern Europe, it is said to be the profile of a woman, while in Germany it has been seen as a man carrying firewood. In Arabia, it has been described as a roaring lion. Among some Indigenous traditions of Canada, it is said to be a girl carrying a bucket. In New Zealand, among the Māori, the markings are associated with a woman named Rona, who was taken to the Moon after angering the Moon god. In many parts of Polynesia and Melanesia, they have been told as the figure of a person cooking over a fire supported by three stones.

The face of the Moon visible from Earth is always essentially the same. Therefore, all of these are interpretations of one and the same pattern. The rabbit, the crab, the old woman, and the crocodile all refer, in terms of the arrangement of light reaching the retina, to the same thing. What differs is the kind of narrative pattern that the observer already carries within them. Where rabbits are absent from the local cultural imagination, no rabbit is seen. Near rivers where crocodiles are familiar, a crocodile may take up residence on the Moon. The ecology of a place, its traditions, and the memories of everyday life become a frame of reference that shapes the image itself.

This may be one of the most familiar examples of a situation in which, even when the physical difference in the object itself is virtually nonexistent, a completely different image can emerge depending on the observer's frame of reference. Against one unchanging physical reality—the pattern on the Moon—countless images can exist in parallel, and each may be perceived as self-evident within its own cultural context. The multiplicity of images is not simply the result of misperception; it is a direct reflection of the multiplicity of frames of reference.

When we look up at a full Moon, it might be said that what appears there is not the Moon's topography itself, but the cultural pattern to which the observer belongs.

This, however, suggests something further in relation to what I call the Theory of Micro-Phase Differences.

The Moon's surface is one fixed composition, while the observer's cultural memory constitutes a second composition superimposed upon it. This is an asymmetric pairing: one composition exists externally as a physical object, while the other exists internally as accumulated memory, experience, and cultural knowledge. Their relationship reveals a source of phase difference distinct from the external-to-external contrasts the theory had previously assumed.

In other words, the second composition does not necessarily have to be another photograph or another physical object. It may exist within the observer.

The image of the rabbit, therefore, is not simply contained in the Moon's surface. It emerges through the encounter between the fixed composition of the Moon and the accumulated composition within the observer. Change the second composition, and the image changes—even though the Moon itself remains exactly the same.

What appears to us as the present is thus not produced by the present object alone. It is formed through the superimposition of what is before us and what we have already carried with us.

The Moon is one, but the images that emerge from it are multiple.

And perhaps this is one of the simplest ways to see what the Theory of Micro-Phase Differences is trying to describe: a difference need not exist between two external objects. A phase difference can arise between the world before us and the accumulated world within us.
