The tilma of Juan Diego, where the image of the Virgin of Guadalupe is located, has survived almost five centuries without the Catholic Church ordering a total repainting of the image. Unlike most of the religious works of the 16th century -which require periodic restorations to remain in good condition-, the Guadalupe image does not show significant deterioration in its main elements, something that has surprised researchers, scientists, restorers and scholars of sacred art.
Most notably, according to analyses carried out by physicist and biologist Phillip Callahan in the 1970s, as well as by restorers from the Basilica of Guadalupe, most of the image does not show the typical layers of paint, primer or varnish typical of 16th century art. Under infrared light, no brush strokes can be detected on the tunic, mantle or face, indicating that the technique used -whatever it may be- does not correspond to the known artistic practices of the time.

1. The image does not show prior preparation on the fabric. Sixteenth century paintings required a base to adhere properly to the material. The tilma does not.
2. The maguey fiber must have disintegrated centuries ago. An average ayate lasts between 20 and 30 years. However, the tilma has withstood humidity, temperature variations, handling and millions of pilgrims, especially before the 20th century, when it had no environmental protection.
3. There is no complete repainting. Restorers point out that there are only minor retouches made centuries later, especially on the hands, the angel and some borders, but the main image remains intact.
Survived an attack
Another important fact is that the tilma has survived incidents that would have destroyed any conventional painting.
The most documented case is the 1921 attack, when a bomb exploded in front of the altar and caused severe damage to the surroundings: broken windows, a twisted bronze crucifix and a fractured floor.
The image did not suffer any visible damage, something that continues to be the subject of study.
Today the tilma is kept under controlled conditions: shielded glass, stable temperature and regulated humidity, but these systems were installed in the 1980s.
By then, the image had already survived more than 400 years without specialized care.

For Hispanics in the United States – many of them living far from their roots and facing immigration, cultural and economic challenges – this mystery carries deep emotional weight.
The image that is venerated in churches in Chicago, Los Angeles, Houston or New York is the same one seen by Indians and Spaniards in the 16th century.
The absence of repainting contributes to that sense of historical closeness: they look at the same tilma, with the same colors and the same shapes that have accompanied generations.
The Catholic Church has never officially proclaimed a supernatural origin for the technique of imaging.
Nor does it officially attribute its preservation to a miracle.
What he does recognize is that the tilma does not fit in with the usual artistic processes and that its preservation is extraordinary from a historical point of view.
Almost five centuries after her apparition, the Virgin of Guadalupe continues to be a living symbol, not only because of her spiritual significance, but also because her image continues to defy the passage of time without having been repainted.
For millions of devotees, especially in the U.S. Latino community, that simple fact reinforces a certainty: the Blessed Mother remains present, intact, in every corner where she is invoked.
