The Florentine Codex is a 16th-centuryethnographic research study inMesoamerica by the SpanishFranciscan friarBernardino de Sahagún. Sahagún originally titled itLa Historia General de las Cosas de Nueva España (in English:The General History of the Things of New Spain).[1] After a translation mistake, it was given the nameHistoria general de las Cosas de Nueva España. The best-preserved manuscript is commonly referred to as theFlorentine Codex, as thecodex is held in theLaurentian Library ofFlorence, Italy.
In partnership withNahua elders and authors who were formerly his students at theColegio de Santa Cruz de Tlatelolco, Sahagún conducted research, organized evidence, wrote and edited his findings. He worked on this project from 1545 up until his death in 1590. The work consists of 2,500 pages organized into twelve books; more than 2,000 illustrations drawn by native artists provide vivid images of this era.[2] It documents the culture,religious cosmology (worldview) and ritual practices, society, economics, andnatural history of theAztec people.[2] It has been described as "one of the most remarkable accounts of a non-Western culture ever composed."[3]
Charles E. Dibble andArthur J. O. Anderson were the first to translate the Codex fromNahuatl to English, in a project that took 30 years to complete.[4] In 2012, high-resolution scans of all volumes oftheFlorentine Codex, in Nahuatl and Spanish, with illustrations, were added to theWorld Digital Library.[5] In 2015, Sahagún's work was inscribed into theMemory of the World register byUNESCO.[6]In 2023, theGetty Research Institute released theDigitalFlorentine Codex which gives access to the complete manuscript.
In 1575 theCouncil of the Indies suggested to the Spanish Crown to educate theIndigenous peoples in Spanish instead of using theIndigenous languages. For this reason, the Spanish authorities required Fray Sahagún to hand over all of his documents about the Aztec culture and the results of his research in order to get further details about this matter.[7] In the meantime, the Bishop of Sigüenza,Diego de Espinosa, who was also theInquisitor General and President of the Royal Council of Castile, instructed the cleric Luis Sánchez to report about the situation of the native Americans.[7] The concerning findings of this report triggered a visit by Juan de Ovando to the Council of the Indies because it demonstrated a total ignorance of the Spanish authorities about the native cultures and, in Ovando's opinion, was not possible to make correct decisions without reliable information.[7] As a consequence, the Council of the Indies ordered to the Viceroyalty of Peru in 1568 that they needed to include ethnographic and geographic information regarding any new discovery within their limits. A similar disposition was given to the Vice-Royalty ofNew Spain in 1569, specifying that 37 chapters were to be reported; in 1570, the extent of the report was modified to required information for 200 chapters.[7] That same year,Phillip II of Spain created a new position as "Cosmógrafo y Cronista Mayor de Indias" to collect and organize this information. He appointed Don Juan López de Velasco, so that he could write "La Historia General de las Indias". His primary focus was a compilation about the history of the Indies.[7]
King Phillip II of Spain concluded that was not beneficial for the Spanish colonies in America and, hence, it never took place.[citation needed] That is the reason why the missionaries, including Fray Bernardino de Sahagún continued their missionary work and Fray Bernardino de Sahagun was able to make two more copies of hisHistoria general. The three bound volumes of theFlorentine Codex are found in theBiblioteca Medicea-Laurenziana, Palat. 218-220 inFlorence, Italy, with the titleFlorentine Codex chosen by its English translators, AmericansArthur J.O. Anderson andCharles Dibble, following in the tradition of nineteenth-century Mexican scholarsFrancisco del Paso y Troncoso andJoaquín García Icazbalceta.[8]
The manuscript became part of the collection of the library in Florence at some point after its creation in the late sixteenth century. It was not until the late eighteenth century that scholars became aware of it, when the bibliographerAngelo Maria Bandini published a description of it in Latin in 1793.[9] The work became more generally known in the nineteenth century, with a description published by P. Fr. Marcellino da Civezza in 1879.[9]
The Spanish Royal Academy of History learned of this work and, at the fifth meeting of theInternational Congress of Americanists, the find was announced to the larger scholarly community.[9] In 1888, German scholarEduard Seler presented a description of the illustrations at the 7th meeting of the International Congress of Americanists.[9] Mexican scholar Francisco del Paso y Troncoso received permission in 1893 from the Italian government to copy the alphabetic text and the illustrations.[10]
The three-volume manuscript of theFlorentine Codex has been intensely analyzed and compared to earlier drafts found in Madrid. The Tolosa Manuscript (Códice Castellano de Madrid) was known in the 1860s and studied by José Fernando Ramírez.[11] The Tolosa Manuscript has been the source for all published editions in Spanish of theHistoria General.[12]
The English translation of the complete Nahuatl text of all twelve volumes of theFlorentine Codex was a decades-long work of Arthur J.O. Anderson and Charles Dibble,[13] an important contribution to the scholarship on Mesoamerican ethno-history. In 1979, the Mexican government published a full-color, three-volume facsimile of theFlorentine Codex in a limited edition of 2,000, allowing scholars to have easier access to the manuscript. The Archivo General de la Nación (Dra. Alejandra Moreno Toscano, director) supervised the project that was published by theSecretariat of the Interior (Enrique Olivares Santana, Secretary). The 2012 World Digital Library high-resolution digital version of the manuscript makes it fully accessible online to all those interested in this source for Mexican and Aztec history.[14] In 2023, theGetty Research Institute released theDigitalFlorentine Codex which gives access to the complete manuscript and multiple translations.

The missionary Sahagún had the goal of evangelizing the indigenous Mesoamerican peoples, and his writings were devoted to this end. He described this work as an explanation of the "divine, or rather idolatrous, human, and natural things of New Spain".[15] He compared its body of knowledge to that needed by a physician to cure the "patient" suffering from idolatry.
He had three overarching goals for his research:
Sahagún conducted research for several decades, edited and revised his work over several decades, created several versions of a 2,400-page manuscript, and addressed a cluster of religious, cultural and nature themes.[17] Copies of the work were sent by ship to the royal court of Spain and to theVatican in the late-sixteenth century to explain Aztec culture. The copies of the work were essentially lost for about two centuries, until a scholar rediscovered it in theLaurentian Library (Biblioteca Medicea Laurenziana) an archive library in Florence, Italy. The Spanish also had earlier drafts in their archives. A scholarly community of historians, anthropologists, art historians, and linguists has since been investigating Sahagún's work, its subtleties and mysteries, for more than 200 years.[18]

TheFlorentine Codex is a complex document, assembled, edited, and appended over decades. Essentially it is three integral texts: (1) in Nahuatl; (2) a Spanish text; (3) pictorials. The final version of the Florentine Codex was completed in 1569.[19] Sahagún's goals of orienting fellow missionaries to Aztec culture, providing a rich Nahuatl vocabulary, and recording the indigenous cultural heritage are at times in competition within the work. The manuscript pages are generally arranged in two columns, with Nahuatl, written first, on the right and a Spanish gloss or translation on the left. Diverse voices, views, and opinions are expressed in these 2,400 pages, and the result is a document that is sometimes contradictory.[18]
Scholars have proposed several classical and medieval worldbook authors who inspired Sahagún, such asAristotle,Pliny the Elder,Isidore of Seville, andBartholomeus Anglicus. These shaped the late medieval approach to the organization of knowledge.[20]
The twelve books of the Florentine Codex are organized in the following way:
Book 12, the account of theconquest of the Aztec Empire from the point of view of the conquered ofTenochtitlan-Tlatelolco, is the only strictly historical book of theHistoria General.
This work follows the organizational logic found in medieval encyclopedias, in particular the 19-volumeDe proprietatibus rerum of Sahagún's fellow Franciscan FriarBartholomew the Englishman. One scholar has argued that Bartholomew's work served as a conceptual model for Sahagún, although evidence is circumstantial.[21] Both men present descriptions of the cosmos, society and nature of the late medieval paradigm.[20] Additionally, in one of the prologues, Sahagún assumes full responsibility for dividing the Nahuatl text into books and chapters, quite late into the evolution of the Codex (approximately 1566–1568).[22] "Very likely," historianJames Lockhart notes, "Sahagún himself devised the chapter titles, in Spanish, and the Nahuatl chapter titles may well be a translation of them, reversing the usual process."[23]
After the facsimile edition became available generally in 1979, the illustrations of theFlorentine Codex could be analyzed in detail. Previously, the images were known mainly through the black-and-white drawings found in various earlier publications, which were separated from the alphabetic text.[24] The images in theFlorentine Codex were created as an integral element of the larger work. Although many of the images show evidence of European influence, a careful analysis by one scholar posits that they were created by "members of the hereditary profession oftlacuilo or native scribe-painter".[25]
The images were inserted in places in the text left open for them, and in some cases the blank space has not been filled. This strongly suggests that when the manuscripts were sent to Spain, they were as yet unfinished.[26] The images are of two types, what can be called "primary figures" that amplify the meaning of the alphabetic texts, and "ornamentals" that were decorative.[27] The majority of the nearly 2,500 images are "primary figures" (approximately 2000), with the remainder ornamental.[28] The figures were drawn in black outline first, with color added later.[28] Scholars have concluded that several artists, of varying skill, created the images.[29] It was deduced that twenty-two artists worked on the images in the Codex. This was done by analyzing the different ways that forms of body were drawn, such as the eyes, profile, and proportions of the body.
It is not clear what artistic sources the scribes drew from, but the library of theColegio de Santa Cruz de Tlatelolco had European books with illustrations and books of engravings.[30] European elements appear in the imagery, as well as pre-Conquest images done in the "native style".[31][32] A number of the images have Christian elements, which Peterson has described as "Christian editorializing".[33] The entirety of the Codex is characterized by the Nahua belief that the use of color activates the image and causes it to embody the true nature, orixiptla, of the object or person depicted. For the Aztecs, the true self or identity of a person or object was shown via the external layer, or skin. Imparting color onto an image would change it so that it was given the identity of what it was portraying. Color was also used as a vehicle to impart knowledge that worked in tandem with the image itself.[34]

The codex is composed of the following twelve books:[35]


Sahagún was among the first people to develop an array of strategies for gathering and validating knowledge of indigenous New World cultures. Much later, the discipline of anthropology would later formalize these asethnography. This is the scientific research strategy to document the beliefs, behavior, social roles and relationships, and worldview of another culture, and to explain these within the logic of that culture. Ethnography requires scholars to practice empathy with persons very different from them, and to try to suspend their own cultural beliefs in order to enter into, understand, and explain the worldview of those living in another culture.
Sahagún systematically gathered knowledge from a range of diverse persons (now known as informants in anthropology), who were recognized as having expert knowledge of Aztec culture. He did so in the native language of Nahuatl, while comparing the answers from different sources of information. According to James Lockhart, Sahagún collected statements from indigenous people of "relatively advanced age and high status, having what was said written down in Nahuatl by the aids he had trained."[36]
Some passages appear to be the transcription of spontaneous narration of religious beliefs, society or nature. Other parts clearly reflect a consistent set of questions presented to different people designed to elicit specific information. Some sections of text report Sahagún's own narration of events or commentary.
He developed amethodology with the following elements:
These methodological innovations substantiate historians' claim that Sahagún was the first anthropologist.
Most of theFlorentine Codex is alphabetic text in Nahuatl and Spanish, but its 2,000 pictures provide vivid images of sixteenth-century New Spain. Some of these images directly support the alphabetic text; others are thematically related; others are for seemingly decorative purposes. Some are colorful and large, taking up most of a page; others are black and white sketches. The pictorial images offer remarkable detail about life in New Spain, but they do not bear titles, and the relationship of some to the adjoining text is not always self-evident. They can be considered a "third column of language" in the manuscript. Several different artists' hands have been identified, and many questions about their accuracy have been raised. The drawings convey a blend of Indigenous and European artistic elements and cultural influences.[37]
Many passages of the texts in the Florentine Codex present descriptions of like items (e.g., gods, classes of people, animals) according to consistent patterns. Because of this, scholars have concluded that Sahagún used a series of questionnaires to structure his interviews and collect data.[20]
For instance, the following questions appear to have been used to gather information about the gods for Book One:
For Book Ten, "The People", a questionnaire may have been used to gather information about the social organization of labor and workers, with questions such as:
This book also described some other indigenous groups in Mesoamerica.
Sahagún was particularly interested in Nahua medicine. The information he collected is a major contribution to thehistory of medicine generally. His interest was likely related to the high death rate at the time from plagues and diseases. Many thousands of people died, including friars and students at the school. Sections of Books Ten and Eleven describe human anatomy, disease, and medicinal plant remedies.[38] Sahagún named more than a dozen Aztec doctors who dictated and edited these sections. A questionnaire such as the following may have been used in this section:
The text in this section provides very detailed information about location, cultivation, and medical uses of plants and plant parts, as well as information about the uses of animal products as medicine. The drawings in this section provide important visual information to amplify the alphabetic text. The information is useful for a wider understanding of thehistory of botany and thehistory of zoology. Scholars have speculated that Sahagún was involved in the creation of theBadianus Manuscript, an herbal created in 1552 that has pictorials of medicinal plants and their uses. Although this was originally written in Nahuatl, only the Latin translation has survived.

Book Eleven, "Earthly Things", has the most text and approximately half of the drawings in the codex. The text describes it as a "forest, garden, orchard of the Mexican language".[39] It describes the Aztec cultural understanding of the animals, birds, insects, fish and trees in Mesoamerica.
Sahagún appeared to have asked questions about animals such as the following:
Plants and animals are described in association with their behavior and natural conditions or habitat. The Nahua presented their information in a way consistent with their worldview. For modern readers, this combination of ways of presenting materials is sometimes contradictory and confusing. Other sections include data on minerals, mining, bridges, roads, types of terrain, and food crops.
TheFlorentine Codex is one of the most remarkable social science research projects ever conducted. It is not unique as a chronicle of encountering theNew World and its peoples, for there were others in this era.[citation needed] Sahagún's methods for gathering information from the perspective within a foreign culture were highly unusual for this time. He reported the worldview of people of Central Mexico as they understood it, rather than describing the society exclusively from the European perspective. "The scope of theHistoria's coverage of contact-period Central Mexico indigenous culture is remarkable, unmatched by any other sixteenth-century works that attempted to describe the native way of life."[40] Foremost in his own mind, Sahagún was a Franciscan missionary, but he may also rightfully be given the title as Father of American Ethnography.[41]
