The Reason for there being no Fixed Time for Human Beings to copulate

Anciently the Creator summoned all the birds and beasts, the gods and devils together, in order to instruct them on the subject of copulation. So the birds and all the others of every sort assembled, and learnt from the Creator when to copulate, and when to give birth to their young.

昔、造物主は、交わりのことを教えるために、あらゆる鳥や獣や神々や悪魔を呼び集めた。そこで鳥をはじめあらゆる種類のものが集まり、いつ交わり、いつ子を産むべきかを造物主から教わった。

Then the Creator said to the horse: "Oh! thou divine ancestor of horses! It will be well for thee to copulate one spring, and to give birth to thy young in the spring of the following year; and thou mayest eat any of the grass that may grow in any land." At these words, the horse was delighted, and forthwith trotted out. But, as he rose, he kicked God in the forehead. So God was very angry, and pressed his hand to his head, so much did it hurt him.

それから造物主は馬に言った。「おお、馬の神なる祖先よ。お前は春に交わり、次の年の春に子を産むのがよかろう。そして、どの国に生える草でも食べてよい」この言葉に馬は喜び、すぐさま駆け出していった。けれども立ち上がるとき、神の額を蹴ってしまった。そこで神はたいそう腹を立て、あまりの痛さに手を頭に押し当てた。

Meanwhile, the ancestor of men came in, and asked saying: "How about me? When shall I copulate?" To which God, being still angry, replied: "Whenever you like!" For this reason, that race of creatures which is called man copulate at all times.--(Translated literally. Told by Ishanashte, 12th July, 1886).

そのあいだに人間の祖先が入ってきて、尋ねて言った。「わたしはどうなのですか。いつ交わればよいのですか」まだ腹を立てていた神は答えた。「いつでも好きなときに!」そのために、人間と呼ばれるその種族は、いつでも交わるのである。——(逐語訳。語り手イシャナシテ、1886年7月12日)
