The Virgin Mary located in the center of the composition with her arms in an attitude of prayer, surrounded by eleven apostles who contemplate the dove of the Holy Spirit, located at the top of an architectural space. The set, which narrates the fifteen mysteries of the Virgin of the Rosary, is one of the most significant works by Joan Grau, the most representative author of the Baroque sculpture school in Manresa. In this altarpiece, the sculptor demonstrates a great mastery of high relief and figures.
