Giovanni Ambrogio Migliavacca


Giovanni Ambrogio Migliavacca was an Italian poet and librettist. A student and protégé of Metastasio, he was primarily active in the court theaters of Dresden and Vienna. His most successful work was the libretto for the opera Solimano, first set by Johann Adolph Hasse in 1753 and subsequently set by 18 other composers in the course of the next 50 years.

Life and career

Migliavacca was born in Milan around 1718, but the exact date of his birth as well as his parentage and early life are unknown. Much of the information about his life has come from Metastasio's letters. Migliavacca's first appearance as a literary figure was in Milan in 1736, when at the age 18 he edited a collection of poetic tributes dedicated to the Duke of Noailles. Soon after, he became a member of the Accademia dei Filodossi and was active in the Milanese intellectual milieu of the Enlightenment. He initially opted for a career as a diplomat, working as the imperial secretary of the Italian legation to the court of Charles VII where he became a favourite of the emperor. After the death of Charles VII in 1745, Migliavacca saw little future in a diplomatic career and instead focused on his literary pursuits.
He moved to Vienna and between 1748 and 1752 worked for Metastasio as a secretary, copyist, and later a collaborator on some of his texts. At the time, Metastasio was the court poet to Holy Roman Empress Maria Theresa. One of his duties was to supervise opera rehearsals and give directions to the singers. When Jommelli's Merope was to be performed in 1749, Metastasio delegated his directorial duties to Migliavacca. Tensions arising from a feud between two of the opera's star singers, Migliavacca's close friend Vittoria Tesi, and the castrato Caffarelli, and from Caffarelli's refusal to attend rehearsals reached a climax when he and Migliavacca fought a duel at Vittoria Tesi's house. However, her entreaties to the combatants ended the incipient sword fight before anyone was hurt.
, Migliavacca's mentor
Migliavacca made his debut as a librettist in his own right in 1750 with Armida placata, composed by and performed in Madrid to celebrate the marriage of Maria Antonia Ferdinanda of Spain and Victor Amadeus III of Sardinia. It was performed again in Vienna later that year in a pastiche version with music by several composers including Luca Antonio Predieri and Johann Adolph Hasse. Through Metastasio, Migliavacca had also become acquainted with Duchess Maria Antonia of Bavaria. She was the wife of Frederick Christian, heir to the thrones of Saxony and Poland, and was a patron of the arts as well as gifted composer, singer, and harpsichordist. Two of her operas, Il trionfo della fedeltà and Talestri, have survived, but according to Bruno Brunelli, she had earlier composed a short opera to a libretto by Migliavacca entitled Giove fulminatore dei giganti.
In 1752, through the intervention of Metastasio, Migliavacca was appointed court poet and diplomatic counselor to Frederick Christian's father Frederick Augustus II. The following year, he produced what was to prove his most enduring work, the libretto for Hasse's opera Solimano. It premiered at the court theatre in Dresden in a spectacular production that included live elephants and camels and hundreds of extras in addition to the seven main singers. His libretto was subsequently set by 18 other composers and saw 36 separate productions over the next 50 years. In 1754 he produced the libretto for Hasse's next opera Artemisia and in 1755 adapted Metastasio's libretto for Hasse's Ezio. Like Solimano, Ezio was a lavish operatic spectacle which included a procession of 400 soldiers and over 100 horses from the royal stable. When the 1756 Prussian invasion of Dresden severely curtailed the musical life of the court, Migliavacca worked in Vienna and then returned to Milan in 1765. During his sojourn in Milan he was instrumental in negotiating the Biblioteca Ambrosiana's acquisition of two valuable book collections belonging to the Clerici and Lambertenghi families.
In 1780 Migliavacca was re-engaged as the poet of the court theatre in Dresden and was paid there regularly through 1795. The cessation of payments after that time without their conversion to a pension suggests that he died shortly after the end of that year. There are no records of the exact date or place of his death. His last known libretto from that period was La reggia d'Imeneo, a festa teatrale performed in Dresden in 1787 to celebrate the marriage of Anton of Saxony. The libretto printed for that performance still listed him as a diplomatic counselor to the Saxony court.
Migliavacca's libretti were long ignored by later literary critics who dismissed them as the work of a semi-dilettante and mediocre imitator of Metastasio. However, in the late 20th century, he came to be appreciated as one of a group of reforming Italian librettists which also included Ranieri de' Calzabigi, Mattia Verazi, Giovanni de Gamerra, and Gaetano Martinelli. They moved away from the traditional Metasasian plot structures, increased the number of ensembles relative to solo arias, and organized the ballets, arias, and ensembles into integrated dramatic scenes rather than the series of showy arias which had previously characterised opera seria.
