Do both Simon Boccanegra and Le roi d'Ys have the same number of acts?
Simon Boccanegra Simon Boccanegra (] ) is an opera with a prologue and three acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the play "Simón Bocanegra" (1843) by Antonio García Gutiérrez, whose play "El trovador" had been the basis for Verdi's 1853 opera, "Il trovatore".
Acta Sanctorum Acta Sanctorum ("Acts of the Saints") is an encyclopedic text in 68 folio volumes of documents examining the lives of Christian saints, in essence a critical hagiography, which is organised according to each saint's feast day. The project was conceived and begun by Jesuit Heribert Rosweyde. After his death in 1629, the Jesuit scholar Jean Bolland ('Bollandus', 1596–1665) continued the work, which was gradually finished over the centuries by the Bollandists, who continue to edit and publish the "Acta Sanctorum".
