Milagros (also known as an ex-voto or dijes or promesas) are religious folk charms that are traditionally used for healing purposes and as votive offerings in Mexico, the southern United States, other areas of Latin America, and parts of the Iberian Peninsula.
They are frequently attached to altars, shrines, and sacred objects found in places of worship, and they are often purchased in churches and cathedrals, or from street vendors.
The use of milagros is a folk custom in parts of North, Central, and South America traceable to ancient Iberians who inhabited the coastal regions of Spain.
Although the custom is not as prevalent as it once was, the use of milagros or ex-votos continues to be a part of folk culture throughout rural areas of Spain—particularly Andalusia, Catalonia, and Majorca.
As part of a religious ritual or an act of devotion, milagros can be offered to a symbol of a saint as a reminder of a petitioner's particular need, or in gratitude for a prayer answered.
