Bella, mother of the protagonist, emerges as a tragic figure forged through years of abuse by her husband, Alighiero. Defined by despair and resignation, she escapes her torment through suicide, an act that fixes her death in 1272—mere years before Alighiero’s swift remarriage, leaving her son motherless by age five or six.

Her suicide condemns her soul to the Wood of the Suicides within Dante’s infernal circle of Violence, where she transforms into a gnarled, tree-like figure suspended by a wooden noose. Her essence intertwines with the twisted flora, bleeding cursed sap and bearing blighted fruit. When her son encounters her during his journey, her arboreal form lashes out violently until subdued, revealing her fractured voice. Through creaking branches, she confesses anguish and regret, pleading for absolution. She surrenders a mystical artifact tied to her torment and implores him to rescue Beatrice, a plea that steers his path forward.

A flashback sequence unveils the harrowing abuse she endured: Alighiero strikes her over misplaced coins, then drags her by the hair in a fit of rage when she fails to account for them. These moments contrast sharply with glimpses of her gentler past as a devout, nurturing figure, her psychological unraveling laid bare. Visually, her hair shifts from dark to stark blonde, mirroring her transition from suffering mortal to spectral memory.

Adaptations diverge in her portrayal: one renders her tree static, communicating only when her bark is torn away; another grants her limbs autonomous, grasping motion. Her dialogue fluctuates between declaring her soul bound to a divine entity and insisting it belongs solely to her son.

Beyond plot function, she forces her son to confront inherited guilt and fractured legacy. Her plea for forgiveness becomes pivotal to his quest for redemption, their fraught reunion underscored by a haunting score that amplifies the gravity of her revelation.
