I'm sure many here are already familiar with these 17th century apparitions of the Blessed Mother but I only recently learned of them and the small but wonderful image which remained afterwards. Analysis and restoration work on the image in recent times has brought to light some hidden and interesting details which have similarities to the larger image at Guadalupe. It doesn't seem to be a drawing or painting and the ink has not been absorbed by the material. Also, as at Guadalupe, the eyes of the image reveal hidden details when looked at under a microscope. This article has some more information about the intriguing image. https://aleteia.org/2018/09/11/has-our-lady-left-us-another-image-of-herself-besides-guadalupe/
A friend who lives in Venezuela shared this Fb post from Sr. Julia Mary Daggenkamp Fsp: "There were only two times when Our Lady left behind an image of herself. One was the well-known image in Guadalupe, Mexico. The other was from her apparition to Coromoto, the chief of the Cospes tribe in Venezuela! In case you’ve never heard the story… Mary appeared by a river in Venezuela in 1651 to the Cospes chief Cacique Coromoto and his wife as he was escaping the Spaniards who had settled in the area. In their native language she told them to go to the Spaniards and ask to have water poured on their heads (Baptism) so they could go to heaven. Surprisingly, he encouraged his tribe and as a result, many natives were baptized. However, Coromoto himself refused Baptism and returned to the jungle. Mary then appeared to him while he was at home with his wife and family. Frustrated, he pointed an arrow at her, demanding, “How long are you going to persecute me?” He tried to grab her arm, and she vanished, leaving him holding a small piece of parchment with the image of Mary and Jesus dressed as members of the Cospes tribe. Although Coromoto was stubborn and rude, he soon gave in and was baptized. After all, the Mother of God had come to visit him personally. Pray to Our Lady of Coromoto for her people in Venezuela!
