in 1897, a novena booklet titled "novena o pagsisiam sa nuestra señora de guia" ("novena to our lady of guidance") was published by the pontifical and royal university of santo tomas in manila. the book recounts the image’s origin story, where natives found it sitting on a trunk, and built a roof above it and the surrounding pandan plants. the text goes on to condemn them for their polytheism, and mentions murder. the image initially received a feast day on 18 december, but the date was transferred to 19 may when a rainstorm hit manila cathedral in february 1771.
