After Isidore's death, Maria became a hermit, but she too performed miracles and merited after her death the name of "Santa Maria de la Cabeza", meaning Head, because her head (conserved in a reliquary and carried in procession) has often brought rain from heaven for an afflicted dry countryside [REF].
After being moved several times, the relics were eventually gathered in 1769 at the Real Colegiata de San Isidro in Madrid where they remain on display for veneration to this day.
