Which opera has more acts, Le prophète or La scala di seta?
La scala di seta La scala di seta (The Silken Ladder or Die seidene Leiter) is an operatic "farsa comica" in one act by Gioachino Rossini to a libretto by Giuseppe Maria Foppa. It was first performed in Venice, Italy, at the Teatro San Moisè on 9 May 1812. The overture has been frequently recorded and continues to be featured in the modern concert repertoire.
Aida Aida (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in Egypt, it was commissioned by and first performed at Cairo's Khedivial Opera House on 24 December 1871; Giovanni Bottesini conducted after Verdi himself withdrew. Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, "Aida" has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.
