For the copy of Raffaello Sanzio's fresco Theology, that takes part of the decoration of the vault of the Stanza della Segnatura in the Vatican Museums, Gabriela developed a 100 cm diameter mural painting using tempera on ceiling.
Gabriela recognized that the image of Our Lady of Guadalupe would be like a codex, where all the drawings have a meaning, representing a synthesis between Christian iconography and Mesoamerican culture.
