A landmark scholarly edition presenting the Codex Xolotl — the great graphic literature of Texcoco — in its own terms. Fifty years of direct engagement by Jerome Offner, now offered to scholars, students, and the public through high-resolution IIIF imaging.
The Codex Xolotl is the exemplar of a localized, vital flowering of Indigenous literature in early postcontact Texcoco. A graphic expression generated by a besieged community, it recorded the rich content of Indigenous culture from the perspectives of the tlacuiloque and patrons who produced it — presenting two centuries of history in the Basin of Mexico from the arrival of Xolotl and the Chichimeca in 1224 CE to the Tepanec War of 1427.
At the heart of the manuscript is the youthful persona of Texcoco's greatest ruler, Nezahualcoyotl — not an all-powerful despot, but a foresightful adventurer, a receiver of wise counsel, a bringer of order, and a promoter of unity. His counterpart, Maxtla, presents the failure of unchecked personal power. Together they articulate a Nahua theory of governance — cooperative, accountable, and resilient — that the tlacuiloque communicated with extraordinary sophistication across ten painted pages.
This digital archive presents Jerome Offner's landmark multi-volume edition of the Codex Xolotl, the product of more than fifty years of sustained, direct engagement with the manuscript. The edition deliberately minimises dependence on alphabetic sources to establish an understanding of the Codex intrinsically and in its own terms — the necessary starting point for accurate comprehension.
"In icuīlōtl in Xolotl" — The painting of Xolotl. Presented here in its emerging role as an agent of acculturation: welcoming, educating, and validating the people of Texcoco — and any modern audience confronting profound upheaval.

Created by anonymous Indigenous tlacuiloque — experts in recording information in graphic form — with limited alphabetic Nahuatl annotations by more than one hand. The manuscript records two centuries of Chichimec and Acolhua history in the Basin of Mexico.
The manuscript was acquired by Indigenous nobleman and scholar don Fernando de Alva Ixtlilxochitl (c. 1568–1648), a descendant of the ruler (tlatoani) Ixtlilxochitl. At his death, his son Juan de Alva Cortés conveyed the archive to the celebrated Mexican-born scholar don Carlos de Sigüenza y Góngora (1645–1700), who willed the Codex to the Jesuit Colegio de San Pedro y San Pablo.
Likely remaining with the Jesuits, the Codex was acquired by Italian scholar Lorenzo Boturini Benaduci (c. 1701–c. 1753). Accused of entering New Spain without a license, Boturini had his entire manuscript collection seized around 1742 and sequestered in the viceregal palace. While there, Antonio León y Gama (1735–1802) made a partial copy.
Following Mexican independence in 1821, French collector Joseph Marius Alexis Aubin (1802–1891) — after twenty years of research and sacrifice — acquired all but Pages 2 and 3, which went to fellow collector Jean-Frédéric Waldeck (c. 1766–1875). Aubin purchased those two pages from Waldeck in France in 1842–1843, branded with Waldeck's name using a hot iron. The collection arrived in Europe around 1840.
French collector and philanthropist Eugène Goupil (1831–1896) purchased Aubin's entire collection in 1889, considering himself only its depositary — intending to bequeath it to France. Upon his death, his widow Augustine Élie Goupil gifted the collection to the Bibliothèque nationale de France in 1898, formalised by decree of President Félix Faure on June 18, 1898.
The Codex Xolotl entered the BnF's Mexican Collection (Fonds Mexicain) as part of the Aubin-Goupil donation, registered under No. 3560. Now held in the World Manuscripts Department (formerly Oriental Manuscripts), the collection constitutes one of the richest collections of Mexican pictographic manuscripts kept by a scientific institution outside Mexico, with 429 catalogue items. A new color digitisation at 600 dpi makes the collection accessible worldwide through Gallica and, for the Codex Xolotl, through this IIIF viewer.

Launch viewer →The Chichimec ruler Xolotl leads his people into the Basin of Mexico. He establishes Chichimec dominion and begins the dynastic genealogy that the Codex traces across generations — its opening act and the foundation of all that follows.
Chichimec rulers intermarry with Toltec nobility and adopt sedentary ways. The codex maps the gradual settlement of the eastern Valley and the coalescence of the Acolhua city-states, with Texcoco emerging at their centre.
Texcoco becomes the intellectual centre of the Aztec world. The art of tlacuilolli flourishes at the Texcocan court, forging the visual language the Codex Xolotl would deploy with such sophistication.
The Codex reaches its dramatic climax: the young Nezahualcoyotl allies with Tenochtitlan and Tlacopan to overthrow the despotic Maxtla. The Triple Alliance is born. Cooperative, accountable governance prevails.
In the wake of the Spanish conquest — plague, looting of the royal archives, the burning of Don Carlos Ometochtzin at the stake in 1539 — besieged Texcocan tlacuiloque compiled and adapted their ancient pictorial tradition in bold reassertion of identity.
J.M.A. Aubin brings the Codex to Europe c. 1840 after twenty years of research. Eugène Goupil purchases the collection in 1889; his widow gifts it to the BnF in 1898. Charles Dibble's 1951 critical edition establishes the methodological commitment to direct engagement that Offner's edition carries forward.
Jerome Offner's first encounter with the Codex Xolotl in 1973 produced an impression of its immense complexity and wisdom. More than five decades of sustained, direct engagement produced the landmark multi-volume edition now presented through the Houston Museum of Natural Science.
Through IIIF-compliant high-resolution imaging and the Mirador 4 viewer, the Codex Xolotl is now accessible to scholars, students, indigenous communities, and the general public worldwide — fulfilling the BnF's commitment to wide dissemination of this exceptional heritage.
