The Dandy Who Learned Japanese: Juan Fernández and the Tongue of the Mission

The Handkerchief at Yamaguchi: How Fernández Won His First Convert, 1550 to 1551

The Uses of a Handkerchief

The most famous moment in Juan Fernández's life takes about four seconds.

It is late 1550 or, perhaps, very early 1551 — the sources are not entirely decided on the date. Fernández is standing on a crossroads in Yamaguchi, the prosperous western-Honshu capital of the Ōuchi clan, doing what he has been doing morning and afternoon every day for weeks: reading aloud from a Japanese translation of a basic Christian catechism to whichever crowd has gathered to hear a foreigner mangle their language. He is twenty-four years old. He is unwell — he is always unwell — and he is explaining, in accented but increasingly intelligible Japanese, who the God of Abraham is and why the listeners ought to be worried about their souls.

Someone in the crowd does not care for this theological program. He shoulders forward through the knot of onlookers, draws level with the young Spaniard, and spits full in his face.

This was, in the sixteenth-century Iberian universe from which Fernández had come, a gesture for which men were ordinarily killed. Spanish gentlemen of the period — and Fernández was a gentleman, a member of the Andalusian hidalgo class, the lower gentry whose touchy pride was proverbial — were, as one of the later Jesuit chroniclers put it, "known to kill for insults a thousand times less grave." The appropriate response was a drawn sword or, failing that, a formal summons to settle the matter with one.

Fernández drew his handkerchief out of his sleeve. The witnesses say only that: a handkerchief. In Japan in 1550 it was in all likelihood the thin, soft, disposable square of paper that the Japanese had been using for centuries, and that was one of the small daily wonders of the country, since Europe at this date was still blowing its nose into the back of its sleeve. He wiped the spittle from his face as though it were sweat. He put the handkerchief away. He resumed reading the catechism.

The man the Jesuits were lodging with, a certain Uchida, had been watching. He had expected a fight. What he got was a man who had, before his eyes, converted a public insult into a non-event by the simple application of a handkerchief. Something in the gesture undid him. Uchida walked home with the foreigners after the sermon ended, asked them a great deal about their doctrine, and in due course became the first Christian convert in Yamaguchi, taking the baptismal name Thomé.

The Jesuits told this story for the next four centuries. They told it because it was true and because it was useful, and because it condensed into a single domestic prop — a handkerchief — the whole of what Fernández was. A man who had surrendered the standard Iberian reflex toward honor-violence and replaced it with something quieter and, in context, more dangerous: the absolute refusal to give the crowd the reaction the crowd expected. He did not shout. He did not draw. He did not even pause. He simply wiped his face.

It was the first lesson in Japanese that Juan Fernández was, by that point, qualified to teach.

From Córdoba to Lisbon: The Silk Merchant Who Joined the Jesuits in 1547

The Silk Merchant of Lisbon

He had not begun as an ascetic. He had not, in fact, begun as anything much recognizable as the man he would become.

Juan Fernández — sometimes, in the records, Juan Fernández de Oviedo, sometimes Juan de Córdoba in deference to his hometown — was born in 1526 in the Andalusian city of Córdoba, that pink-tiled old Umayyad capital whose great mosque had been converted into a cathedral only a few years before he drew his first breath. His family was wealthy. His father was a merchant. His status was the lower rung of the Spanish gentry, the hidalguía — a class whose defining characteristic, in the sixteenth-century imagination, was an unbearable sensitivity to its own dignity combined with, often, a chronic shortage of cash. A young hidalgo was expected to live quietly off whatever income the family had and refrain from occupations considered beneath his birth. Commerce was such an occupation.

Fernández, who appears to have been practical where his class was proud, ignored all of this. Together with his elder brother he moved to Lisbon — the hot-breathing maritime capital at the mouth of the Tagus — and the two of them set themselves up as silk merchants. It is a detail worth pausing on, because the silk trade of Lisbon in the 1540s was the hinge of a commercial system that stretched from the mulberry groves of China to the dye-vats of Flanders. The silk that would soon flow from Macao to Nagasaki aboard the Portuguese Great Ships — the silk that would build the fortunes of the Nau do Trato, told in the dedicated article on the Black Ship trade — was the same fiber, from the same mulberries, that young Juan Fernández had been measuring out by the yard in a Lisbon warehouse.

He prospered. Georg Schurhammer, the twentieth-century Jesuit biographer whose monumental Francis Xavier: His Life, His Times remains the indispensable source on the early Japan mission, has him running a silk-and-velvet business on the Rua Nova dos Mercadores. He had money. He had style. He had, by the standards of his milieu, arrived: a dandy in his day, a leader of fashion, wealthy and accomplished.

And then, with the abruptness that is the special signature of the mid-sixteenth-century religious life, he gave it all away.

In the spring of 1547, at the age of twenty-one, Juan Fernández presented himself at the Jesuit house in Lisbon and asked to be admitted to the Society of Jesus. What had broken the young man's life in two was a sermon. A friend had taken him to Santo Antão, the Jesuit church, to hear the excellent music; he got the Passion instead, and when the preaching ended the lights were put out and the men in the church began to scourge themselves. He went back to make a general confession, came in while Francisco de Estrada was preaching, and was carried away by that fiery eloquence. Simão Rodrigues received him in Lisbon and sent him on to the novitiate at Coimbra, where he entered on 19 June 1547 — as a lay brother, not a priest, a status he would insist on keeping for the rest of his life. Within a year his superiors had decided he was the right kind of convert to send very far away.

He boarded the ship São Pedro, which left Lisbon on 28 March 1548. In the same fleet, aboard the Galega, sailed a sixteen-year-old named Luís Fróis, who was himself making the same outbound voyage to Portuguese India and who would eventually become the greatest European chronicler Japan ever had. Fernández landed in Goa on 3 September 1548; Fróis's ship did not come in until 9 October. Francis Xavier was waiting there.

Why Francis Xavier Chose Fernández for Japan and Let Him Refuse Ordination

Xavier's Eye

Xavier, whose spectacular career as co-founder of the Society of Jesus and self-appointed evangelist of Asia is treated at length in his dedicated article, was at this point forty-two years old and planning an enterprise so ambitious it bordered on the reckless. He had met the Japanese fugitive Anjirō in Malacca the previous year, heard his reports of a "rational" and "honor-bound" kingdom at the far edge of Asia, and decided that Japan would be the next mission field. He needed companions who could survive a pirate junk, a typhoon, a winter in Kyushu, and the inevitable theological hazing by Buddhist clergy.

He watched Fernández for a few months at the College of Saint Paul. What he saw was a man of slight build, permanent ill health, and an almost conspicuous refusal of comfort. Fernández had been assigned to the laundry and the sick-room. He mended his brothers' shirts in the clothes-room with a Latin grammar propped open on his knee, sewing and reading simultaneously to save time. He prayed three or four hours a day on his knees, and if daylight labor prevented him he prayed at night. He chose deliberately, from the house's stock of worn possessions, the poorest and meanest things for his own use.

What was unusual was the contrast. The fine mind was still there. The social polish was still there. The taste and quickness of the silk merchant's son had not been lost, only redirected. Xavier, whose instinct for people was the best thing about him, saw that this intelligent former dandy was exactly what the Japan mission needed.

There was only one problem. Xavier wanted to ordain him before departure. Fernández wept and begged to remain a simple lay brother. Xavier — the formidable Basque commander who had bent kings and viceroys to his purposes — bent. "Out of pure compassion," the sources tell us, he gave way.

This refusal of orders would turn out to be one of the strangest and most consequential facts about the early Japan mission. For the next eighteen years, in the most delicate theological conversations that Europeans had ever conducted with Asians, the words that would actually reach Japanese ears would come out of the mouth of a man who was not, by the Society's own standards, ordained to speak them.

The three Europeans — Xavier, the senior priest Cosme de Torres (whose own story is told in his dedicated article), and Fernández — sailed from Goa in April 1549, boarded a Chinese pirate junk on 24 June, and landed at Kagoshima on 15 August 1549. On the way, Fernández had already started, patiently and without fuss, to learn Japanese from Anjirō.

How Well Did Juan Fernández Speak Japanese? The Voice of the Mission from 1549

The Tongue

The claim that Juan Fernández was the greatest European speaker of Japanese of the sixteenth century is not, strictly, what his contemporaries said. What they said was stronger.

Father Balthasar Gago, writing home in 1555, recorded that Fernández "spoke Japanese better than his mother tongue" — that after six years in the country the Andalusian had become, linguistically, more Japanese than Spanish. Luís Fróis, personally tutored in the language by Fernández in the early 1560s, described him as possessing a very sharp mind and great prudence, and noted with exasperated affection that Fernández had by the end become so stubbornly committed to the language that he refused to speak anything but Japanese even to newly arrived Portuguese priests and merchants, continuing while his interlocutors grew visibly angry at being unable to understand him.

This was not a scholarly eccentricity. It was an occupational necessity. Fernández had been, from the first week of the Kagoshima landing, the public voice of the mission. Xavier himself struggled badly with Japanese throughout his two-year residency, memorizing Anjirō's phonetic catechism by rote and reciting it in a broad-vowelled approximation that the chroniclers politely describe as having amused small children. Fernández made the most rapid progress of the three Europeans, and by the late autumn of 1549 he was the one Xavier turned to whenever an actual conversation needed to happen with an actual Japanese person.

This matters because the political architecture of the early mission depended on conversations. When Shimazu Takahisa, the daimyō of Satsuma, received the Jesuits in his hall at Ijūin, eleven miles from Kagoshima, on 29 September 1549 and agreed to permit their preaching, the words that passed between the warlord and the priests passed through Fernández's mouth. When Takahisa changed his mind the following year — having observed that the Portuguese trading ships had bypassed Kagoshima in favor of Hirado and having drawn the obvious conclusion about the cost of hosting missionaries who could not deliver commerce — it was Fernández who had to translate the prohibition, a prohibition that carried the death penalty. When Xavier walked into the catastrophic first audience with Ōuchi Yoshitaka at Yamaguchi and began reading aloud, for over an hour, from a Japanese text that turned out to contain a scathing condemnation of sodomy — a form of erotic life at which the Ōuchi court notoriously excelled — it was Fernández who read the thing, watching the daimyō's face harden, unable to stop because the catechism was what they had. Yoshitaka terminated the meeting without a word.

The disaster of that audience, and the subsequent fruitless winter trek through knee-deep snow to an emperor in Kyoto who had no political power to give them, is told in the Xavier article. When the Jesuits returned to Yamaguchi in silk vestments bearing gifts of a mechanical clock and a music box and crystal goblets, it was Fernández again who performed the second embassy, and Fernández whose Japanese carried off the renegotiation that delivered them the abandoned Buddhist temple of Daidō-ji and permission to preach freely.

About five hundred Japanese Christians were baptized at Yamaguchi in the following months. One of them was a near-blind twenty-five-year-old itinerant lute-player named Ryōsai, who took the baptismal name Lourenço and whose extraordinary subsequent career as the first Japanese Jesuit lay brother is told in his own article. The conversations that produced that congregation happened in Japanese, and the Japanese was Fernández's.

The Yamaguchi Disputations of 1551: Interpreting Jesuit Theology for Buddhist Monks

The Disputations and the Burning City

In September 1551 Xavier received word that a Portuguese ship had made landfall in Bungo and that the twenty-two-year-old daimyō of that province, Ōtomo Sōrin (Yoshishige), desired an audience. Xavier departed for Funai, leaving the Yamaguchi mission in Cosme de Torres's hands — and, practically speaking, in Fernández's. Torres was a grammarian, not a linguist; he could think about Japanese, but he could not yet speak it. Fernández was the tongue the two of them shared.

What unfolded in Yamaguchi in the days that followed would become known as the Yamaguchi Disputations, and they are the first sustained theological debate ever conducted, anywhere, between European Christians and Japanese Buddhists. The Cosme de Torres article tells the broader story of how the Jesuits arrived at this confrontation — how the initial catastrophic decision to translate "God" with the Shingon Buddhist term Dainichi had been reversed, and how the missionaries had switched to the Latin Deus. What that account cannot describe, because it belongs to this article, is what it was actually like to sit, hour after hour, in the Daidō-ji temple and render into Japanese the Aristotelian arguments of Cosme de Torres as they arrived at him in Spanish.

Fernández did this for nine days, from 15 to 23 September 1551. He sat between Torres and a succession of the most highly educated Buddhist clergy in the Ōuchi domain — Zen scholars, Shingon masters, Tendai doctors — and carried, back and forth, across the gulf between two philosophical languages that had no shared vocabulary, the entire intellectual apparatus of sixteenth-century Jesuit theology. He rendered the existence of a single Creator. He rendered the immortality of the soul. He rendered — most offensive of all to the Buddhist ideal of the universal compassion of the Bodhisattva — the doctrine of eternal damnation.

He took notes as he translated. On 20 October 1551 he compiled those notes into a written report and sent it to Xavier in Bungo. The autograph is lost, but the text survives in a copy made the following year, and Schurhammer printed it in 1929. It was the first systematic European study of Japanese Buddhist philosophy, and for the next half-century — through the era of Valignano, through the Azuchi Debate of 1579, through the long afternoon of the Christian Century — it provided the Society of Jesus with the theological intelligence on which its whole Japan mission rested. Every argument that Vilela would later deploy in Kyoto, every refutation that Valignano would commission for publication at the Jesuit press, traced back through Fernández's notebook to a specific autumn week in a Yamaguchi temple where a former silk merchant was listening, very carefully, to what the monks were saying.

He was doing this in the middle of a civil war.

On 23 September 1551 — the last day of the disputations — word ran through the city that the senior Ōuchi retainer Sue Harukata had risen in revolt against the patron who had granted the Jesuits their temple. A week later, on the 30th, Ōuchi Yoshitaka was forced into seppuku at the Tainei-ji temple. The city went up. The sources describe Yamaguchi overflowing with blood for the space of eight days. Torres and Fernández, foreigners in a blazing city, were forced to flee and go into hiding. It is Fernández's own report that records how they survived: the wife of the Ōuchi retainer Naitō-dono sent word that they were to come to her house at once, and sheltered them there — a detail remarkable enough that he sets it down in his own first person, because European foreigners rarely enjoyed the direct protection of samurai women. They came out of the burning city alive. Fernández's notebook survived the fire with them.

Fernández's Grammar of Japanese, 1564, and the Takushima Fire of 1563

The Grammar and the Lost Library

What nobody quite understood, in the years they watched Fernández translate for Torres, was that he was also, on his own time, going to produce something the mission had never had.

The Jesuit Japan mission had arrived without a grammar. It had arrived without a dictionary. It had arrived, linguistically speaking, with Anjirō's phonetic catechism and the sheer determination of its members to make themselves understood. This was not sustainable. The mission would shortly be receiving new arrivals from Goa, young men who would need to learn Japanese themselves, and they could not all apprentice directly under Fernández the way Fróis eventually would. What was needed was a book.

In 1564 — Fróis, writing that year, places the labor at six or seven months of intensive work — Fernández produced one. It was called the Arte, after the standard term for a grammar, and it contained conjugations, syntax, and the basic rules of the language. Accompanying it were two alphabetical vocabularies: one Portuguese-to-Japanese, the other Japanese-to-Portuguese. The dictionary and grammar of Japanese had entered European literature. Boxer records an earlier pair compiled by Padre Duarte da Silva, so Fernández's were not quite the first of their kind; they are the ones the sources actually describe. The man who wrote them was a lay brother from Córdoba.

The work was not published in his lifetime. It was copied, by hand, and passed from missionary to missionary as they arrived in Japan over the following decades. Beside it lay the labor of his earlier years: his own translations of the Gospels for the Sundays of the liturgical year, the Passion narratives read on Good Friday, and Japanese commentaries on the Our Father, the Hail Mary, the Apostles' Creed and the Decalogue. These manuscripts were the living library of the early Japan mission — the texts from which sermons were preached and from which the first generation of Japanese Christians learned what their new religion actually said.

Most of them were destroyed in a fire.

Around 1563, on the small island of Takushima where Fernández had been stationed with the newly arrived Luís Fróis specifically to teach Fróis the language, a fire broke out. A substantial portion of the manuscripts and fascicules went up with the building. The missionaries wrote home about the loss with the grief of men who had watched years of labor burn. Fernández, as far as the sources record, did not complain. He got up and started rebuilding — the Arte and its two vocabularies are the work of the twelve months that followed — though by this point he had less than four years to live.

What survived — in copies, in extracts, in the intellectual DNA of the mission — would outlast him by centuries. When João Rodrigues, the great Portuguese Jesuit grammarian, published the Arte da Lingoa de Iapam in Nagasaki between 1604 and 1608, the book usually credited as the first European grammar of Japanese, he was building on foundations Fernández had laid forty years earlier in a room on the Kyushu coast. Rodrigues's work is larger, more systematic, and properly printed on the Jesuits' own press. Fernández's was the seedbed.

Fernández's Reminiscences: How We Know What Francis Xavier Was Like

Xavier, in the Voice of His Interpreter

There is another reason Juan Fernández matters to the historical record, and it has nothing to do with grammars.

Francis Xavier is one of the most important figures in the history of Asian Christianity, and by far the most difficult to see as a person. His hagiographers made him a saint; his critics made him a fanatic. Almost everything we think we know about Xavier the human being, as opposed to Xavier the figure, comes through one particular conduit: the reminiscences that Fernández dictated to Fróis in the early 1560s, in the quiet years after Xavier was dead, when the lay brother was tutoring the younger man in Japanese.

It is from Fernández that we get the picture of Xavier on the winter trek to Kyoto, half-starved and barefoot in the Sanyō snow, amusing himself by wearing a borrowed Siamese cap or turban and skipping along the road singing — "never at any time did I see him display more gaiety than on this occasion." It is from Fernández that we learn about the scoffing merchant on the boat who treated Xavier "now as a fool, now as a brute beast," and about Xavier responding to the abuse only with what Fernández called a sweet sadness. It is from Fernández that we know Xavier could be both formidable and boyish, a man whose vocation had not entirely suppressed the Basque aristocrat's sense of humor.

These are the details that make Xavier a human being rather than a statue. They survived because Fernández was the man in the room, and because — thirteen years later, teaching a younger Jesuit to conjugate Japanese verbs — he thought to mention them. Xavier was the saint. Fernández was the memory.

The two of them had loved each other. Xavier wrote home to Goa, challenging the brilliant preacher Gaspar Barzaeus with a standard: What do you say of João Fernández? He is so virtuous and works so much that in order to become his equal you will have to work much. Xavier selected Fernández for the Japan mission because, as Schurhammer puts it, he could not have found a better companion. The pirate-junk crossing, the Kagoshima landing, the winter road to Kyoto, the burning city of Yamaguchi — they had done all of it together.

Xavier left Japan in November 1551 and died on Shangchuan Island off the Chinese coast in December 1552, waiting for a junk to the mainland that would never come. Fernández stayed.

How Juan Fernández Died at Hirado on 26 June 1567

Hirado, 1567

He stayed for sixteen more years. He worked under Torres in the ruin of the Yamaguchi mission, and then in the relocation to Bungo under the protection of Ōtomo Sōrin, and then in the scattering of the mission across the small Kyushu stations of the 1560s. He taught Fróis Japanese at Takushima. He translated, and preached, and mended his own clothes, and prayed on his knees three or four hours a day in the manner he had adopted at Goa and never once relaxed. In his late thirties, evidently deciding he was not yet fully stretched, he began studying Chinese — the Jesuits were already dreaming of a Chinese mission, and Fernández was, characteristically, preparing himself for the door that had not yet opened.

He ministered, at the end, in Hirado. The port had been one of the earliest of the Portuguese anchorages in Japan — the daimyō Matsuura Takanobu had welcomed Xavier there in 1550, because the Satsuma route had failed and because, as always, favor tracked the Black Ship. A small Christian community had survived in Hirado through the subsequent years of turbulence. Fernández translated for the local congregation, preached indefatigable sermons, practiced the severe mortifications that had defined his spiritual life from Goa onward, and refused, to the last, any suggestion that his health might require him to ease back.

On 23 June 1567, the vigil of the Nativity of John the Baptist, a fever took him. He was forty-one. He had been in Japan for just under eighteen years.

Brother Jacobe Gonçalves, who was with him at the end, wrote the letter that records the deathbed. Fernández, delirious with the fever, continued to preach in Japanese — the language had sunk so deep into him that the dying body still produced it automatically, one last catechism for an audience he could not see. Around the bed stood the Japanese Christians he had baptized and instructed: Dom Antonio, Dom João, Dona Isabel, the whole local congregation that had come to regard the Córdoban lay brother as something closer than a priest. He died on 26 June 1567.

The wailing from the Hirado congregation, Gonçalves wrote, was so loud that one could no longer hear the other. The Japanese Christians considered him their father. They kissed his feet. They buried him in the church square, under the cross, and then — in a gesture for which the sources can find almost no parallel in the early mission — they surrounded the grave with an iron grille, as one might shield a saint's tomb from ordinary hands.

His old superior, Cosme de Torres, delivered the only verdict that mattered. "If Japan has to thank Father Xavier for having brought her the faith," Torres said, "she has to thank Brother Fernández for its conservation after the departure of the saint."

Torres was saying what Fernández himself would never have admitted. The Japan mission had been held together by the language skills of a lay brother who had, eighteen years earlier, been a silk merchant on the Tagus.

Juan Fernández's Legacy: Conversation, Ordination and the Jesuit Silk Trade

The Silk Merchant's Legacy

Three things deserve saying, at the end, about the life of Juan Fernández.

The first is that the mission he served was a mission of conversation. The Jesuit program in Japan did not operate by military conquest or by mass baptism under duress. It operated by argument — by sitting down with a Zen abbot and trying to convince him, in his own language, that the universe had a Creator. This whole program rested on the simple technical requirement that someone on the European side be able to speak Japanese fluently enough to handle philosophical vocabulary. For the mission's first eighteen years, that someone was almost exclusively Fernández.

The second is that the status of the man was a theological puzzle. The Society of Jesus is an order built around the priest. Fernández was a lay brother by his own insistence for the whole of his career. He administered no sacraments and heard no confessions. And yet the theological authority of the early Japan mission — the actual doctrinal content that arrived in Japanese ears — was in practice his voice and his wording, because the priests who held the orders could not speak the language in which the doctrine had to arrive. Fernández simply refused to be ordained, and the Society simply had to do its theology through him.

The third is the matter of the silk. The whole improbable enterprise of the Nanban century rested on a structural marriage between evangelization and commerce. The Jesuits articulated it with disarming frankness — the preachers take the Gospel and the trade takes the preachers — and in the decades after Fernández's death they would formalize it in the Jesuit silk quota and the cession of Nagasaki to the Society of Jesus in 1580. Fernández himself, formed as a Lisbon silk merchant before he was ever a Jesuit, was the perfect early-mission hybrid.

Juan Fernández died young, in a provincial Japanese port, far from the Córdoban gentry he had left behind. The hidalgo who had gone to Lisbon to sell silk, and had renounced both the silk and the gentry to enter the Society of Jesus, and had crossed half the world to translate catechisms for street crowds who sometimes spat at him, was buried under an iron grille in Hirado by people who kissed his feet and called him father. There are a great many ways to end a life. Very few of them are quite so far from where they started.

The silk-merchant's son had become, in the vocabulary of the chronicler who memorialized him, a faithful and true servant of God. The memory of such a man, Fróis wrote, would always remain alive to coming generations.

And so, after a fashion, it has.
