The Rosary (Latin: rosarium, "rose garden", Spanish:Rosario), is a traditional devotion in the Catholic Church.
To pray the rosary you should use a Rosary. A Rosary is a string of beads with a crucifix. A short string of five beads is attached to the crucifix which leads to a large circular strip of beads made of five sets of one large bead and ten smaller beads, called decades. You begin on the crucifix with a Sign of the Cross and an Apostles' Creed. Say an Our Father on the large bead and one Hail Mary for each of the next three smaller beads. On the next large bead, say a Glory Be to the Father, announce and meditate on the first mystery and say an Our Father. Say a Hail Mary for each of the following smaller beads, and end the decade with the Glory Be. Begin the cycle again with an Our Father, meditate the second mystery according to the same schema and so on for the third, fourth and fifth mysteries. You end with the Prayer after the Rosary and a Sign of the Cross.

By tradition, the Catholic laity began the practice of saying the rosary in honor of the Blessed Virgin and as an easier imitation of the monastic practice of praying the 150 Psalms. The first historical evidence of the rosary is from Saint Dominic (A.D. 1221), who founded Order of Preachers or Dominicans. A disciple of Saint Dominic, Alain de Roche, instituted the modern form of the rosary. Many Popes, and particularly the Dominicans, have urged the regular recitation of the rosary, which means a crown of roses as a spiritual bouquet given to the Blessed Mother.
Rosary in Latin
In nomine Patris, et Filii, et Spiritus Sancti. Amen
(the Apostles' Creed):
Credo in Deum Patrem omnipotentem, Creatorem caeli et terrae. Et in Iesum Christum, Filium eius unicum, Dominum nostrum, qui conceptus est de Spiritu Sancto, natus ex Maria Virgine, passus sub Pontio Pilato, crucifixus, mortuus, et sepultus, descendit ad inferos, tertia die resurrexit a mortuis, ascendit ad caelos, sedet ad dexteram Dei Patris omnipotentis, inde venturus est iudicare vivos et mortuos. Credo in Spiritum Sanctum, sanctam Ecclesiam catholicam, sanctorum communionem, remissionem peccatorum, carnis resurrectionem, vitam aeternam. Amen.
(the Our Father):
PATER NOSTER, qui es in caelis, sanctificetur nomen tuum. Adveniat regnum tuum. Fiat voluntas tua, sicut in caelo et in terra. Panem nostrum quotidianum da nobis hodie, et dimitte nobis debita nostra sicut et nos dimittimus debitoribus nostris. Et ne nos inducas in tentationem, sed libera nos a malo. Amen.
(the Hail Mary):
AVE MARIA, gratia plena, Dominus tecum. Benedicta tu in mulieribus, et benedictus fructus ventris tui, Iesus. Sancta Maria, Mater Dei, ora pro nobis peccatoribus, nunc, et in hora mortis nostrae. Amen.
(the Glory Be):
GLORIA PATRI, et Filio, et Spiritui Sancto. Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen.
