“In riding a horse, we borrow freedom”
The use of worn horseshoes as lucky amulets originated in Europe. There is good reason to suppose the the crescent form of the horseshoe links the symbol to pagan moon goddesses and later to the Vigrin Mary, who is often depicted standing on a crescent moon.
Horseshoes are commonly nailed above or beside doors to “gather luck”. The potency of the horseshoe amulet is associated with San Martin Caballeros, or Saint Martin the horse-rider, who cut his cloak in half and gave it to a beggar. That night he dreamed that Jesus was wearing the half-cloak. Consequently, he was baptized and for the remainder of his life, he worked among the poor.
