The Memoirs of Jacques Casanova de Seingalt, 1725-1798. Volume 29: Florence to Trieste

The dreadful Nina Bergonci, who had made a madman of Count Ricla, and was the source of all my woes at Barcelona, had come to Bologna at the beginning of Lent, occupying a pleasant house which she had taken. She had carte blanche with a banker, and kept up a great state, affirming herself to be with child by the Viceroy of Catalonia, and demanding the honours which would be given to a queen who had graciously chosen Bologna as the place of her confinement. She had a special recommendation to the legate, who often visited her, but in the greatest secrecy.

The time of her confinement approached, and the insane Ricla sent over a confidential man, Don Martino, who was empowered to have the child baptized, and to recognize it as Ricla's natural offspring.

Nina made a show of her condition, appearing at the theatre and in the public places with an enormous belly. The greatest noble of Bologna paid court to her, and Nina told them that they might do so, but that she could not guarantee their safety from the jealous dagger of Ricla. She was impudent enough to tell them what happened to me at Barcelona, not knowing that I was at Bologna.
