Carlo il Calvo – ‘Charles the Bald’ – was first performed in 1738 at Rome’s leading opera house, the Teatro delle Dame. The cast consisted entirely of men and castrati.

The score has been preserved at the Conservatory in Naples.

Its distinctive feature is that the titular hero is a child. In contrast to his colleagues, Porpora even gives him some verses to sing. Louis the German, Charles’ half-brother and Charlemagne’s grandson, abducts the legitimate heir to the throne in order to rob him of his sovereignty.

In the role of Louis, seduced into doing evil by treacherous advisers, Max Emanuel Cencic has the chance to launch into pathological hysteria. Only Franco Fagioli, as the noble knight Adalgiso, has what it takes to put a stop to the tyrant and re-establish the God-given order. But in doing so, Louis’s son comes into conflict with the fourth commandment…
