Jerome Barberin toils in Paris while his wife nurtures their adopted son in a rural French village. A crippling injury forces his return home, transforming him into a man marked by physical scars and a harsher temperament. Mounting debts and festering resentment over raising another’s child push him to expose the protagonist’s origins as a Parisian foundling.

Confronted by poverty, he coldly negotiates the child’s sale to Vitalis, a wandering entertainer, dissolving kinship for pragmatic gain. The transaction reflects his view of the boy as a burden rather than a son. This mercenary choice irrevocably severs ties and sets the protagonist’s odyssey in motion, though Barberin himself fades from the tale thereafter.

Later reinterpretations, including gender-swapped iterations, preserve his essence: a pragmatic and unsentimental figure prioritizing survival over sentiment. His narrative influence remains rooted in early plot developments, confined to the narrative’s opening acts without elaboration on his subsequent life or latent motivations beyond instigating the child’s exile.
