This "Crown of Prayers" is a Rosary of the Seven Joys of the Blessed Virgin Mary.  It has its roots in an ancient Franciscan sacramental that began in A.D. 1422.   

Novena, meaning nine in Latin, is a specific prayer or set of prayers that are prayed for nine days straight.  

Litany is from the Latin litania, letania, or Greek lite, meaning prayer or supplication.  It is a responsive petition of praise, mercy, or intercession.
