The rosary
On most statues of Lourdes, the Virgin holds a rosary in her hands. The Virgin actually appeared to Bernadette holding a rosary. Bernadette had one. Bernadette says herself that at the time of the Apparitions, she only knew her rosary, that is the " I believe in God ", the " Our Father ", the " I salute you Mary " and the "Glory to the Father".
