Copy of Stone of Tizoc (1481-1486 CE)

This small-scale model in the collections of the Museum of World Culture in Gothenburg is a faithful miniature of the monumental Stone of Tizoc (Piedra de Tízoc). Known also as the Sacrificial Stone, the original is one of the most striking surviving monuments of the Aztec empire. Carved in the late 15th century in Tenochtitlan, it combines imperial propaganda, cosmological symbolism, and a contested role in human sacrifice. The model lets visitors examine, up close, the intricate reliefs and the puzzling central depression that has sparked centuries of debate.

Created Under Tizoc’s Rule

The original Stone of Tizoc was created between 1481 and 1486 CE during the short reign of the Aztec emperor (tlatoani) Tizoc. It is a massive cylindrical monolith of basalt or andesite, roughly 2.65 meters (about 104 inches) in diameter and 93–94 cm (approximately 36.6–37 inches) high, weighing around 9.5 tons. Fifteen repeated scenes circle its side: a victorious Mexica warrior—often identified as Tizoc himself, wearing the regalia of Huitzilopochtli and Tezcatlipoca—seizes a captive by the hair, the classic Mesoamerican gesture of defeat. Each captive is labeled with a place glyph naming a conquered town or province. The top surface shows a sun disk; bands of stars and earth monsters frame the whole composition, turning the cylinder into a cosmogram of the Aztec world.

Rediscovered on 17 December 1791 during the repaving of Mexico City’s Zócalo (the heart of the former sacred precinct of Tenochtitlan), the stone was nearly broken up for building material. A passing cleric named Gamboa intervened and saved it. It later stood vertically against the cathedral, moved to the university, and today occupies a place of honor in the National Museum of Anthropology in Mexico City.

The Carved “Bowl” That Was Never Meant to Be There

The most debated feature is the shallow circular depression in the center of the top face, together with a rough channel that runs from the center to the edge and down one side, cutting through the solar disk and one of the conquest scenes. The cut is crude, asymmetrical, and clearly later than the original reliefs. Richard Townsend argued that the depression was made in the 16th century for unknown reasons. Spanish-language scholarship and other studies often place the channel in the 17th century. It does not appear in Bernardino de Sahagún’s detailed 16th-century description. Several specialists, including Eduardo Matos Moctezuma, interpret the damage as deliberate post-conquest alteration—possibly by early Spaniards—to reinforce sensational colonial stories of Aztec “barbarism” or simply to reuse the stone.

A comparable monument, the Stone of Moctezuma, lacks this channel. The anecdote therefore captures a real historical intervention: the “bowl” visitors notice was almost certainly hollowed out long after the Aztecs carved the stone, most likely in the 16th or 17th century.

Blood, Stars, and the Theater of Empire

Within Aztec culture the stone served as both political statement and ritual instrument. Its reliefs advertise Tizoc’s (and the empire’s) military successes and frame them as part of the cosmic order: sky above, earth below, solar power at the center. Scholars debate its precise function. It may have been a vessel that received the hearts of sacrificial victims—or the round platform used in gladiatorial-style sacrifices in which a bound captive fought fully armed warriors. Many researchers place it among the paired ritual cylinders associated with the Yopico temple of Xipe Totec, the flayed-skin god. In either reading, the monument linked the emperor’s victories to the ongoing need for blood to keep the sun moving and the world in balance.

Basalt, Scale, and the Craft of the Model

The original is carved from dense volcanic stone (basalt or andesite). Its dimensions—diameter approximately 265 cm / 104 inches, height 93–94 cm / 36.6–37 inches—make the human figures and glyphs impressively large yet still finely detailed. The miniature model reproduces these proportions and the principal reliefs, including the later central depression and channel. While the exact size of the Gothenburg model is not listed, it is small enough to be handled or closely inspected. Such models were common in 19th- and early 20th-century ethnographic and archaeological collections, allowing scholars and the public to study monuments that remained in Mexico.

From a Mexican Seller to a Swedish Museum

The miniature entered the collections of what was then the ethnographic department of Gothenburg Museum in 1936, acquired from the seller M. Frankell. It is recorded in the 1936 annual report. The object has since been exhibited in temporary shows and is currently part of the permanent holdings of the Museum of World Culture.
