Abstract

美しき過ち, utsukushiki ayamachi, is not a set saying: none of the dictionaries opened carries it, and on this design it is a rendering made in February 2010 for an English phrase. The words were not new: an essay of 1907 calls a woman's error of feeling a beautiful mistake, verse had set the classical form down by 1915, and since 2013 it has twice been the Japanese title of a foreign work. English mistake runs from an error one learns from, through a wrong one owns, to a love one should not have had, and in slang to an unplanned child; the noun 過ち covers the first three in its dictionary senses, and the classical 美しき gives the phrase the distance of a title. In the Japanese print that could be read, the phrase is used of feeling, of love and of sin, and never of the happy accident the English often means.

Overview

The sense. Literary: a classical adjective form kept today for titles and poems, on a common noun. A mistake, a wrong or an affair that one holds as beautiful, which is the spread the English has too. 過ち, ayamachi, is the noun the phrase turns on. デジタル大辞泉 gives it four senses: 1 まちがい。失敗, a mistake, a failure, with the example 過ちを恐れず試みる, try without fearing mistakes; 2 犯してしまった罪。過失, a wrong one has committed; 3 男女間の不倫。不義, an affair; 4 an injury, classical [1]. デジタル大辞泉 also gives the Confucian line its own entry, 過ちては改むるに憚ること勿れ, 《「論語」学而から》過ちを犯したら、ためらわないで改めよ, when you err, do not hesitate to mend it [2]. So the one noun runs from the error one learns from, through the wrong one owns, to the affair, with the moral tinge that English mistake also carries when it is serious.

The words. 美しき, utsukushiki, is the classical attributive of 美しい, beautiful, the form a noun follows; modern Japanese keeps it for titles and poetry, and three film and drama titles of 1991 to 2005 use it, each the Japanese title of a foreign work [3][4][5]. In the 精選版日本国語大辞典's account of the word, 美し was first a love for one's own kin and for small things, and came to mean beauty in general only by the Meiji period; the 枕草子's list of うつくしきもの, lovely things, begins with a child's face drawn on a melon [6].

The text in English. The English phrase is old. In Mary Russell Mitford's verse tragedy Foscari (1826) Foscari tells his friend, Oh, how I love the beautiful mistakes / Of thy unbounded charity!, the errors of a man too generous to suspect anyone [7]. In E. E. Cummings's play Him (1927) a woman says to the man she has left, as they speak of the mistake of their lives, It may take two people to make a really beautiful mistake [8]. In 1960 Julius Nyerere, asked how his party had come so far so fast, says of the colonial government, They made some beautiful mistakes: mistakes that turned out well, for the other side [9]. In P!nk's song Crystal Ball (2008) the singer is learning to be brave in my beautiful mistakes [10]; and Wikipedia's page for the phrase lists a homewrecker first [11]. Mistake alone also means, in slang since 1957, an unplanned child [12]. Beautiful in front of it chooses none of these. The Japanese noun covers the error, the wrong and the affair in its dictionary senses; the child is not among them. The alternatives each narrow it: 失敗 to failure, 罪 to sin, 過失 to negligence, 誤り toward the correctable error; and 間違い, the one noun broader than 過ち, is plain speech under a classical adjective [13][14][15][16][17]. The first Japanese–English dictionary, Hepburn's of 1867, gives ayamachi as a mistake, error, fault, a wrong, with no affair, and its English index sets it under accident [18]; JMdict glosses 過ち as fault; error; indiscretion; faux pas and 美しい as beautiful; pretty; lovely; sweet; pure [19]. The phrase itself has no bilingual dictionary entry: JMdict has none, and the Japanese–English dictionaries read, from Hepburn (1867) to Kenkyūsha (1983), searched in their text layers for its romaji, its kanji and the English, do not carry it.

The historical record

1907, 1915, and after. The words in Japanese before the rendering. The modern form is in 生田長江's 『文学入門』 of 1907, of a woman who errs by following her feelings: それは實に女らしい過ちである。美しい過ちである, it is truly a womanly mistake; it is a beautiful mistake, and better, the sentence goes on, that a woman give her feelings rein and make a large mistake, and a womanly one, than a small one by leaning on intellect and will [20]. The classical form, with あやまち in kana, is in verse by April 1915, in the women's magazine 處女: わが美しきあやまちに似て晝の月, the moon by day, like my beautiful mistake, a line the index's excerpt runs on into かなしかりけ…, was sad; the excerpt does not name the poet [21]. A poem that ends 悔いやあるもと美しき過ちを美しと見てなせるわれらに, regret? — to us, who saw the beautiful mistake as beautiful and made it, is quoted by two critics in 1994 and 1999, and the National Diet Library's full-text index finds its words in the collected tanka of 三ヶ島葭子 (1886–1927), published in 1993, which is the footing for calling it hers; the excerpts begin partway into the poem, and when she wrote it is not established here [22][23][24]. In 1958 a critic writes 「美しきアヤマチ」 in quotation marks, for something he sets against 醜悪なる小利口さ, ugly petty cleverness; what it names is not clear from the excerpt [25]. A sentence printed in 美術手帖 in 1969, and in 加藤郁乎's 『遊牧空間』 in 1970, speaks of 自分のピエタとの美しきあやまち, a beautiful mistake with one's own Pietà [26]. In 1988 a book of advice for young women calls a youthful love affair a so-called beautiful mistake, 美しきあやまち……とかいう [27], and in a book of tanka of 1999 美しき過ちよ罪よ, beautiful mistakes, sins, are called foolish to lament [28]. The index finds five more uses, in 1939, 1983, 1984 and twice in 1985, without an excerpt [29]. Of the uses that can be read, the clearest are of feeling (1907), of something two people made (三ヶ島葭子), and of a youthful love affair (1988); none is a happy accident.

2010. The phrase on this design is a rendering made in February 2010 by Master Takase, for a customer who asked for the English phrase as a design and cited P!nk's Crystal Ball (2008) [30][10].

2013 and 2015. Two titles. A Taiwanese drama of 2012, 罪美麗, An Innocent Mistake, in which a man of forty-five, remarried after his first wife's death, falls for a young woman, was broadcast in Japan in 2013 as 台北ラブストーリー〜美しき過ち [31]. The Japanese title of Beautiful Mistake, a 2015 episode of the American series The Originals, is 美しき過ち [32].

Today. In Japanese, 過ち alone is the serious word: a usage guide calls it the somewhat formal cousin of 間違い, used for the fault that is judged by social or moral norms [33], and in 一夜の過ち, one night's mistake, it names an affair [34]. 美しき in front of it gives the phrase the poetic distance of a title, and lets the reader bring their own case to it. Whether a Japanese reader meeting the phrase cold hears a beautiful sin or the poem first, no dictionary settles. The Japanese idioms for the happy accident by itself are other phrases, 怪我の功名, a lucky break from a blunder, and 失敗は成功のもと, failure is the seed of success [35][36].

What is not a source. This is not a Japanese saying: none of the dictionaries opened gives it as an idiom. The two titles above are the only ones found, and both belong to foreign works; no Japanese song, novel or film with the phrase as its title was found in what could be searched. The verse and prose above are in the National Diet Library's full-text index, which reaches the Japanese books and magazines the library has digitized, mostly from before 2000; the Japanese lyric databases refused an automated search, and no catalogue of later Japanese novels, films or songs was searched.

A reading

The characters are sound, the register is right, and the phrase does the one thing a translation of this English has to do: it holds the mistake, the wrong and the affair the reader brings to it, and beautiful mistakes, plural and unspecified, is the English that keeps it. The two ranges overlap; the weights do not. The Japanese print that could be read uses the words for feeling, for love and for sin, so the wrong and the affair come forward in Japanese, and the happy accident, which the English often means, is reached only through 過ち's first sense. That is the cost of the rendering, and it is a small one: no other noun carries the English's range in this register.

Sources not seen

The 1915 number of 處女 and the three later books that print the poem given to 三ヶ島葭子: her collected tanka of 1993, and the critics' books of 1994 and 1999. Each is quoted from the excerpt the National Diet Library's full-text index returns; the pages are served only to registered readers in Japan or inside the library. The pages would show who wrote the 1915 verse, and where and when 三ヶ島葭子 first printed hers. The books of 1958, 1969, 1970, 1988 and 1999 are quoted the same way.

The five uses the index finds without an excerpt: 青虹 (1939), 短歌 (1983), 水甕 (1984), 覇王樹 (1985) and 短歌人 (1985), the last written 美しき誤ち.

The Japanese lyric databases. They refuse an automated search, so no Japanese song lyric was searched for the phrase.
