Editing Our Lady of Guadalupe (section)

====Sol Rosales====
In 1982, [[Guillermo Schulenburg]], abbot of the basilica, hired José Sol Rosales of the [[Instituto Nacional de Bellas Artes y Literatura]] to study the image. Sol Rosales thought that the ''tilma'' was made of linen and hemp, and not either agave or cotton. Contrary to previous claims, he said that the fabric had been prepared with white paint before the image had been painted. He saw several different styles of [[tempera]] throughout the image. He held that the paints were made from various natural pigments, and further noted that all of these pigments were commonly available in 16th-century Mexico. Like Flores Gómez, Sol Rosales saw various touch-ups and repainting throughout the image.<ref name="Rosales study">{{cite magazine |last1=Vera |first1=Rodrigo |title=El análisis que ocultó el Vaticano |trans-title=The analysis that the Vatican hid |magazine=Proceso |issue=1333 |date=May 18, 2002 |url=https://www.proceso.com.mx/187569 |url-status=dead |archive-url=https://web.archive.org/web/20190401145956/https://www.proceso.com.mx/187569 |archive-date=April 1, 2019 |language=es}}</ref>

Sol Rosales concluded that the image was of human origin. He claimed that others, like Cabrera, had had similar findings, but concluded that the image was divine due to social pressures.<ref name="Rosales study"/> Sol Rosales and his team were supervised during the investigation by Schulenburg and others. Schulenburg sent the results of this study to the Vatican, cautioning against the canonization of Juan Diego.<ref name="Gomez interview"/>
