Casanova was cared for by his grandmother Marzia Baldissera while his mother toured about Europe in the theater. His father died when he was eight. As a child, Casanova suffered nosebleeds, and his grandmother sought help from a witch: "Leaving the gondola, we enter a hovel, where we find an old woman sitting on a pallet, with a black cat in her arms and five or six others around her."[7] Though the unguent applied was ineffective, Casanova was fascinated by the incantation.[8] Perhaps to remedy the nosebleeds (a physician blamed the density of Venice's air), Casanova, on his ninth birthday, was sent to a boarding house on the mainland in Padua. For Casanova, the neglect by his parents was a bitter memory. "So they got rid of me," he proclaimed.[9]
Conditions at the boarding house were appalling so he appealed to be placed under the care of Abbé Gozzi, his primary instructor, who tutored him in academic subjects as well as the violin. Casanova moved in with the priest and his family and lived there through most of his teenage years.[10] It was also in the Gozzi household that Casanova first came into contact with the opposite sex, when Gozzi's younger sister Bettina fondled him at the age of eleven. Bettina was "pretty, lighthearted, and a great reader of romances. ... The girl pleased me at once, though I had no idea why. It was she who little by little kindled in my heart the first sparks of a feeling which later became my ruling passion."[11] Although she subsequently married, Casanova maintained a lifelong attachment to Bettina and the Gozzi family.[12]
