Isabel, Catalina’s Sister

Isabel, Catalina’s Sister, is a central example in Catalina’s reflections on how marriage and bereavement can transform a person. Remembered first as a worldly young woman who fell in love on her wedding day, she later returned home after her husband’s death, grieving and longing for convent life; when obliged to marry again, she did so unwillingly. Her story also belongs to the family’s wider experience of loss, including the death of her young son Miguel.

Identity and Family

Isabel was Catalina’s older sister and the mother of Miguel, who died at two years old. Catalina describes her mother as having kept Catalina close for comfort after the deaths of her son Prince Juan and her grandson Miguel, and as facing the departure of her last child from home. Isabel’s experience is therefore part of a family history in which political succession and personal bereavement repeatedly meet.

Isabel’s life also unfolded across kingdoms. She went to Portugal to marry, and Catalina recalls that the marriage took her far from her family. The account distinguishes Isabel’s return after her husband’s death from the separate loss of María of Aragon, who died in Portugal after going there to marry; it does not describe the circumstances of Isabel’s own return beyond her husband’s death.

Marriage, Bereavement, and Change

Before her first marriage, Isabel seemed to Catalina vain and worldly. After her husband died and she came home, her priorities changed: she wanted to enter a convent, and Catalina describes her heart as broken. The contrast matters because it shows not a fixed character portrait but a life altered by loss.

Catalina also remembers that Isabel fell in love with her husband on their wedding day and said that she would never love again. She nevertheless had to marry a second time, and did so unwillingly. The account gives no further details about that marriage, but makes clear the difference between Isabel’s personal wishes and the obligations placed upon her.

Influence on Catalina

Isabel’s history enters a conversation between Catalina and Arthur about Harry’s character and capacity for love. Arthur insists that Harry will remain selfish and that nobody will break his heart. Catalina answers by recalling Isabel: someone who once seemed worldly could be changed profoundly by love and bereavement. When Arthur dismisses the possibility that Harry has a heart, Isabel’s experience supplies Catalina with a direct rebuttal to his certainty.

The example carries a second, more difficult implication. Isabel’s first love did not protect her from bereavement, while her later marriage was undertaken unwillingly. Catalina’s recollection thus holds affection and dynastic obligation together without treating them as the same thing. In a family where marriages also served political purposes, Isabel’s changing fortunes make the human costs of those arrangements visible through the sisters’ own history.

Loss and Narrative Significance

Isabel is characterized through what Catalina remembers of her: a youthful reputation, a love formed at marriage, grief after her husband’s death, and reluctance toward a subsequent marriage. The narrative offers no independent account of Isabel’s thoughts or later life, so her importance lies chiefly in the way her experience is preserved and interpreted by her sister.

Her story also stands within a chain of family losses. Catalina links the deaths of Prince Juan and Miguel to the futures that vanished with them, while Isabel’s own bereavement and separation from home give that dynastic history a personal dimension. For Catalina, Isabel is not merely a cautionary tale about marriage; she is evidence that people can change, love deeply, and suffer consequences that political arrangements cannot undo.
