The words
比翼 hiyoku is paired wings: 比 to set side by side, 翼 a wing. 連理 renri is joined grain: 連 to join, 理 the grain of wood, so two trunks whose grain has grown into one. Neither half names a bird or a tree; each is the short form of a longer phrase, 比翼の鳥 the wing-paired bird and 連理の枝 the branch of joined grain, and the four characters are the two short forms set together, sky first and earth second, in the order the poem gives them. The bird is a Chinese legend older than the poem: 南方有比翼鳥焉，不比不飛, in the south there is a wing-paired bird; unless paired, it does not fly, says the 爾雅, the oldest Chinese glossary, and a commentator added that each has one eye and one wing. The tree is an omen before it is a love word: Chinese histories record trees whose two trunks had grown together as signs of a virtuous reign, and the Japanese court did the same, 阿波国献木連理, the province of Awa presented a tree of joined grain, in 704. The love story under the tree is in the 搜神記, a fourth-century book of marvels: a king takes a man's wife, both die, the king buries them apart, and overnight two catalpas grow from the graves, 屈体相就，根交于下，枝錯于上, bending toward each other, roots crossing below, branches interlaced above, with a pair of mandarin ducks in them crying; the people called it 相思樹, the tree of longing.
A history, from the earliest witness
806, 白居易, 長恨歌, The Song of Everlasting Sorrow, a narrative poem. The emperor 玄宗 has lost 楊貴妃, strangled by his own soldiers on the flight from the capital; a Taoist finds her spirit on an island of the immortals, and she sends back the one thing only the two of them knew: 七月七日長生殿，夜半無人私語時。在天願作比翼鳥，在地願為連理枝。天長地久有時盡，此恨緜緜無絶期, on the seventh day of the seventh month, in the Hall of Long Life, at midnight with no one near, we whispered: in heaven let us be the wing-paired birds, on earth let us be branches of one grain. Heaven is long and earth is old, but they will end; this sorrow goes on and has no end. The vow is remembered by a dead woman about a love that broke a dynasty. [zh.wikisource 長恨歌, text; the variants 作/為 and 絶/盡 are marked there.]
927, 延喜式, the court's book of procedures, book 21. Among the auspicious signs a province must report to the Ministry of Ceremonies: 比翼鳥。狀如鳧。一翼一目。不比不飛, the wing-paired bird: shaped like a duck, one wing, one eye; unless paired, it does not fly. The bird enters Japanese as a legal category of good omen. [6]
About 1008, 紫式部, 源氏物語, the chapter 桐壺. The emperor grieves for Genji's mother: 朝夕の言種に、「翼をならべ、枝を交はさむ」と契らせたまひしに、かなはざりける命のほどぞ、尽きせず恨めしき, morning and evening it had been his word to her, "we shall set our wings side by side, we shall cross our branches"; that her life had not allowed it was a grief without end. The whole chapter is built on the 長恨歌, and the 1673 commentary 呉竹集 glosses this line in four characters: はねをならべ枝をかはすとは比翼連理なり。深きちぎりを云也, to pair wings and cross branches is hiyoku renri; it means a deep pledge. [7][15]
Mid-eleventh century, 浜松中納言物語, a court romance set partly in China. A Chinese emperor, missing a dead empress, recites the line over and over on a moonlit evening: 「天にあらば比翼の鳥となり、地にあらば連理の枝とならむ」とおし返しつゝずんじ給へる, "in heaven a wing-paired bird, on earth a branch of one grain," he chanted again and again. The first Japanese witness for 連理の枝 in kana. [8]
1202, 吾妻鏡, the Kamakura shogunate's chronicle, the fifteenth day of the eighth month. A dancer at the shogun's court takes the tonsure: 此女。日來古郡左衛門尉保忠密通。成比翼連理契之處。保忠下向甲斐國。不待歸來。有此儀。不堪悲歎之故也, this woman had lately been in a secret affair with 古郡保忠 and had made with him the pledge of wing-paired birds and joined branches; 保忠 went down to Kai, and unable to wait for his return she did this, because she could not bear her grief. The first time the four characters stand together in a Japanese text, and they name an adultery. [10]
About 1296, 宴曲集, banquet songs. In a song of the court's year: 玄宗皇帝の楊妃が肩にかゝりて比翼連理と契りし, the emperor 玄宗, leaning on 楊貴妃's shoulder, pledged wing to wing, branch to branch. The phrase sung in Japanese with its Chinese lovers named. [11]
Fourteenth century, 太平記 and 義経記, war tales. The 太平記 retells the Taoist's journey and quotes the line in Chinese, 在天願作比翼鳥、在地願為連理枝。と誓き. The 義経記 uses the halves of a woman who changes her mind: 昨日までは連理の契り、比翼の語らひ浅からず … 夜の程に女心変りをぞしたりける, until yesterday the pledge of one grain, the talk of paired wings, were not shallow; in the space of a night the woman's heart changed. [ja.wikisource 太平記/巻第三十七 and 義経記, text.]
1702 to 1813, the Edo stage and fiction. 比翼連理とちかひにし, they had sworn hiyoku renri (東海道敵討, 1702); 牽牛織女の絶ぬ契を羨て比翼連理と誓ひし, envying the unbroken pledge of the Herdsman and the Weaver, they swore hiyoku renri (双蝶記, 1813). In 1797 the first origami book names a crane design 比翼 and gives it a comic verse on the vow: 天にあらばひよくのちぎりたのしまん かすミの蒲團 雲どりの夜着, in heaven we would enjoy the wing-paired pledge, a quilt of mist and bedclothes of cloud. The phrase is by now every lovers' word, high and low. [16][18]
1918 and 1940, two wedding manuals. A handbook for Shinto priests, in its chapter on marriage rites: 其の間に於いて始めて比翼連理の契りを結び, in that moment they first tie the pledge of hiyoku renri. A manual for the newly married, under the heading husband and wife are one body: 又比翼連理と云ふ言葉がありますが、鳥がむつまじく翼を比べてゐる樣に、連理は他の木の枝と枝とが連なつて一しよになり、同じ木輪になる樣に、夫婦ももとは他人と他人とであるが一つになつて了ふと云ふ意味で, there is also the phrase hiyoku renri: as birds lovingly set wing beside wing, and as renri means one tree's branch joining another's and growing to the same rings, so husband and wife, who began as strangers, become one. By 1940 the phrase is explained to brides as what marriage plainly means. [19][20]
The sense across time
One sense, held steady for twelve centuries: two who are so joined they are one creature. What moves is who it is said of. In the poem and the romances it is the pledge of lovers, remembered in grief; in the Kamakura chronicle it is an adultery; on the Edo stage it is any oath between a man and a woman; in the Diet Library's books it climbs through the Meiji and Taishō novels to a peak in the 1920s and by then it is in the priests' handbooks and the brides' manuals as the ordinary picture of marriage. The dictionaries split on the word: 大辞泉 says 夫婦, husband and wife; the 日国 says 男女, a man and a woman, and its two first citations, an affair and an imperial concubine, are why. Beside it stands 比翼塚, the shared grave of lovers who died together, which keeps the poem's shade.
What is not a source
The 搜神記's tree of longing is the picture behind 連理 but not its name; the word is an omen in the Han histories and the Japanese court before it is a love word. The Herdsman and the Weaver of 七夕 are the setting of the vow, the seventh night of the seventh month, not its source, though the 1813 novel joins them. 偕老同穴, grow old together, share one grave, is the phrase's older partner from the 詩経 and is often said in the same breath; it is a different phrase with its own history, and the priests' handbook and the brides' manual give the two together.
The text in English
1901, Herbert A. Giles, A History of Chinese Literature, London: Heinemann, pp. 174–175. In his version of the poem, titled The Everlasting Wrong: How on the seventh day of the seventh moon, in the Hall of Immortality, / At midnight, when none were near, he had whispered in her ear, / "I swear that we will ever fly like the one-winged birds, / Or grow united like the tree with branches which twine together." Two footnotes: Each bird having only one wing, must always fly with a mate, and Such a tree was believed to exist, and has often been figured by the Chinese. The first full English poem found, and it carries the legends in its notes. [archive.org, historyofchinese0000herb_v0s8, text; the OCR reads T swear.]
1929, Witter Bynner with Kiang Kang-hu, The Jade Mountain, New York: Knopf, p. 124. Under the title A Song of Unending Sorrow: "On the seventh day of the Seventh-month, in the Palace of Long Life, / We told each other secretly in the quiet midnight world / That we wished to fly in heaven, two birds with the wings of one, / And to grow together on the earth, two branches of one tree." The rendering most quoted since, and the one that gives the images without the footnotes. [archive.org, jademountain0000witt, text.]
Searched and not found. Fletcher's Gems of Chinese Verse (1919) has 楊貴妃 poems by other hands but not this one; Waley's More Translations from the Chinese (1919) and Giles's Chinese Poetry in English Verse (1898) have nothing. [archive.org texts, searched.]
Today. JMdict gives marital vows, which names the use and not the picture. The shopping agent that recommended the phrase glossed it two birds that fly only together, two trees with one root; that is the legend under each half, and it is fair. A rendering must keep both images and their order, sky then earth: wing to wing, branch to branch, or Bynner's two birds with the wings of one, two branches of one tree. The house has no English for it yet.
A reading
This is the best-sourced wedding wish within the shop's reach, and its source is a tragedy. The characters say paired wings, joined grain; the legends under them are a bird that cannot fly alone and two trees that grew into one over a grave; the poem that joined them is a dead woman's memory of a whispered promise; and the first Japanese to write the four characters together was a Kamakura clerk explaining why a dancer had cut off her hair over a man who did not come back. None of that is a reason not to brush it. For seven hundred years the tradition has used it for any two people who mean to be one, and by 1940 it was being taught to brides as the plain meaning of marriage. The sky-then-earth pair is as good a picture of two lives as the language holds, and it reads without ambiguity in four characters. A page that sells it should tell the poem, the emperor and the consort and the vow at midnight, and let the buyer take the tragedy with it or not. If Eri makes a design, the one thing I would ask her is whether the phrase reads to her today as a wedding word or keeps its shade; the account signs it as a wedding word.
Notes
The order 比翼連理 outnumbers 連理比翼 eighteen to one in the Diet Library's books. The 1626 and 1661 Edo prints of the 吾妻鏡 show the passage in the index but the page API did not find the four characters on them, so the 1905 typeset is the witness. The 1797 origami book's design 比翼 is the same book that gives 千羽鶴 its early history. Bynner's page number is from the running head of the 1929 printing.
