According to Letaille, the official painter of the Rue du Bac visions (1841), St. Catherine saw Our Lady crowned with 12 stars with the moon under her feet. Our Lady of Guadalupe also appeared standing on the moon. This image encompasses the apocalyptic moment of the fulfillment of Our Lady of Guadalupe and Revelation. Our Lady of America also revealed herself in this way. This apparition received canonical approval and Sr. Mary Ephrem describes, in remarkable detail, the vision of November 1957 as follows,

“Our Lady appeared, standing on a globe, her right foot resting on a crescent moon, the left on a snout of a small fire-breathing dragon.”

In Catholic thought, the moon is symbolic of Mary. Just as the moon reflects the light of the sun, so too, Mary reflects the grace and mercy of Christ for souls. The crescent moon, together with the 12 stars, is symbolic of the book of Revelation. The moon of mercy eclipses the sun of justice.

“As [Mary] is the dawn which precedes and reveals the Sun of Justice, who is Jesus Christ, she must be seen and recognized in order that Jesus Christ may also be.”

The crescent moon has another meaning: It has two points that appear like two horns; and just as Mary crushes the head of the serpent, fulfilling Genesis 3:15, so too, she will play a vital role in crushing the head of the two-horned dragon, foretold in Revelation.
