The aguacate, called palta in Peru and "perales" in Tierra Firme
A royal chronicler files the avocado among the wild trees the Christians called "pear trees" — then reports the same trees planted by hand in Nicaraguan town squares and cultivated by the Indians, and concludes that everything was wild before human industry took it in hand. A Jesuit in Peru describes it under its Andean name, tells the hard-skinned Peruvian fruit from the thin-skinned Mexican one, and would still rather eat a European pear. Archaeobotany has dated the industry Oviedo guessed at.
Why this wins its question: English-language accounts of the avocado's history run on etymology — the Nahuatl ahuacatl and its anatomical joke — and on a vague "the Aztecs ate it", with no document under either. This object gives the two sixteenth- century texts as printed: the chapter Oviedo filed under wild pear trees, the sentence in which he revises that judgement after seeing the trees planted in Nicaraguan plazas, his note that the fruit ripens off the tree and goes well with cheese, Acosta's Peru-versus-Mexico distinction of 1590, and Acosta's refusal to prefer it to a European pear. Then it puts the 2025 El Gigante chronology beside them, so that the chronicler's guess about human industry can be read against a dated eleven-thousand-year record of it — and it marks the avocado identification as the nineteenth-century editor's, which the popular accounts never do because they have not opened the page.
Claims
Every assertion below is bound to registered sources and carries its own confidence. Weight them; do not treat the page as uniformly authoritative.
Gonzalo Fernández de Oviedo gives the fruit a chapter of its own in the ninth book of his Historia general y natural de las Indias, headed "CAPITULO XXIII. De los perales salvajes de la Tierra-Firme". He places them in the governorship of Castilla del Oro, "en las sierras de Capira é en tierra del caçique de Juanaga, é en otras partes de la lengua de Cueva", where there are "unos árboles hermosos é grandes que los chripstianos llaman perales; y de hecho la fructa que llevan, son peras en el talle y en la color, é no en mas". The name is the settlers' analogy; Oviedo records no name for the tree in the language of Cueva he places it in.
His description is a working one. The skin is "tan gordo como de un borçeguí de cordoban"; the stone inside is not a stone but "una pepita, cubierta de una telica delgada, que proveyó natura, porque lo que se come desta fructa no tocasse á la pepita, que es amarguíssima"; many of the fruits weigh a pound; the leaf is like a laurel's but larger and greener; and cut with a knife the kernel "paresçe castaña inxerta mondada".
He also records the handling practice that the fruit requires, which is the practice still used. They never ripen on the tree; the largest are taken and put "en un rincon de casa sobre un poco de hierva ó de paja seca, é alli se maduran, como haçen las servas en España"; once ripe the rind cuts away easily and the kernel comes free of itself, "é lo que queda de comer paresçe manteca é es un gentil manjar, é yo le tengo por mejor que las peras de Castilla". He adds that they are very good with cheese, and that if the moment is let pass they sour and rot and are worth nothing.
The most valuable sentence in the chapter is Oviedo correcting himself. Having filed the tree among the wild ones — he had said in the reportorio he wrote at Toledo for the Emperor in 1526 that in such woods "solamente el hortolano es Dios" — he writes that some years later, in the province of Nicaragua, he saw many of these trees "puestos á mano en las heredades é plaças ó assientos de los indios, é por ellos cultivados", some as large as walnut trees, their fruit smaller than those of Cueva. On the next page he draws the conclusion: the tree could equally have gone in the preceding book among the fruit-bearers, "pero no es inconviniente: que primero fueron todos salvajes que la industria de los hombres en curar dellos se ocupasse".
That the chapter is about the avocado is stated by the edition's nineteenth-century editor and not by Oviedo. A footnote keyed to the chapter title in the Real Academia de la Historia printing reads "Este árbol es el aguacate, que los hay de tres generaciones. En algunas provinçias del Nuevo Reyno llámasse cura." The identification is recorded here as an editorial one, at the confidence that carries, though the description above matches nothing else.
José de Acosta describes the same fruit fifty-five years later under its Andean name, in the chapter of the Historia natural y moral de las Indias headed "De los Mameyes, y Guayauos, y Paltos": "Las Paltas al reues son caliêtes y delicadas. Es el Palto arbol grande, y bien hecho, y de buena copa, y su fruta de la figura de peras grandes: tiene dentro vn huesso grandezillo: lo demas es carne blanda, y quando estan bien maduras, es como mãteca, y el gusto delicado y mãtecoso." The two men, writing from opposite ends of the Spanish Indies and without either naming the other's word, reach the same comparison independently: it tastes like butter.
Acosta then records a regional difference that no later observer had to rediscover: "En el Piru son grandes las paltas, y tienen cascara dura, que toda entera se quita. En Mexico por la mayor parte son pequeñas, y la cascara delgada que se monda como de mançanas: tienenla por comida sana, y que algo declina a calida". Two kinds of avocado, distinguished by size and by whether the skin peels whole or like an apple, are on the record in Spanish in 1590.
The counterpoint is printed by the Jesuit himself, on the next page. Having listed the peaches, apples and pears of the Indies — "Mameyes, y Guayauas, y Paltas" — he adds "aunque yo antes escogeria las de Europa: otros por el vso, o aficion quiça ternan por buena o mejor aquella fruta de Indias", and closes the chapter admitting that readers who have never tasted these fruits will make little of the passage, "y aun les cansarà el oyllo, y a mi tambien me va cansando". The corpus of European praise for American fruit is smaller than it is usually made to look, and one of its standard witnesses is here declining to give it.
What Oviedo inferred from a Nicaraguan town square, archaeology has dated. A 2025 report on directly radiocarbon-dated desiccated and carbonised avocado remains from El Gigante rockshelter in western Honduras covers "the last 11,000 y" and finds that measurements of seeds and rinds "show evidence for long-term management resulting in selection for larger, more robust fruits through time that culminated by 2,250 to 2,080 calendar B.P.", with "human-directed selection for larger fruits with thicker rinds … evident as early as 7,565 to 7,265 cal. B.P." The trees the Spaniards met were the product of a breeding programme some seven millennia old.
The same report attributes the El Gigante material to a named variety: "Seed morphology is similar to P. americana var. guatemalensis and is congruent with genetic data for the development of this variety in both the highlands of Guatemala and Honduras", and its opening position is that avocados "were domesticated multiple times in the Americas", with seed exchange, hybridisation and cloning essential across a wild range running from Mexico to South America.
What this object does not claim. It does not identify Acosta's large hard-skinned Peruvian paltas and small thin-skinned Mexican ones with the horticultural races of modern pomology: Acosta names no varieties, the 2025 report says nothing about the sixteenth century, and the resemblance between the two statements is left as a resemblance. Nor is Oviedo's chapter treated as the earliest European notice of the fruit; he himself refers back to an earlier book of his own of 1526, which was not read for this object.
