The image of Our Lady of Guadalupe is often read as a coded image. Miguel Sanchez, the author of the 1648 tract Imagen de la Virgen María, described the Virgin's image as the Woman of the Apocalypse from the New Testament's Revelation 12:1: "arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars." Mateo de la Cruz, writing twelve years after Sánchez, argued that "the Guadalupe possessed all the iconographical attributes of Mary in her Immaculate Conception".<3> Likewise, a 1738 sermon preached by Miguel Picazo argued that the Guadalupe was the "best representation" of the Immaculate Conception.<3>
Many writers, including Patricia Harrington and Virgilio Elizondo, describe the image as containing coded messages for the indigenous people of Mexico.<4><5>
"The Aztecs...had an elaborate, coherent symbolic system for making sense of their lives. When this was destroyed by the Spaniards, something new was needed to fill the void and make sense of New Spain...the image of Guadalupe served that purpose."<6>
Her blue-green mantle was described as the color once reserved for the divine couple Ometecuhtli and Omecihuatl;<7> her belt is interpreted as a sign of pregnancy; and a cross-shaped image symbolizing the cosmos and called nahui-ollin is said to be inscribed beneath the image's sash.<8>
Yet another interpretation of the image is offered by the historian William B. Taylor, who recounted that Guadalupe has also been "acclaimed goddess of the maguey
" and pulque was drunk on her feast day. A 1772 report described the rays of light around Guadalupe as maguey spines.<9><10>
