A False Twin Diagnosis

Hope Against Evidence
A miscarriage and reassurance
Katherine loses a daughter, but an English physician claims another twin remains. The court’s hope for an heir makes uncertainty difficult to challenge.
An anxious queen
Katherine continues the supposed pregnancy despite bleeding and the absence of movement. Her private doubts become a dangerous conflict between evidence and expectation.
Yusuf’s First Counsel

An Unwelcome Truth
A secret consultation
Katherine allows María de Salinas to bring Yusuf, a Muslim physician trained in the learning of al-Andalus. Her inherited hostility makes the meeting difficult from the start.
The likely diagnosis
Yusuf tells her that the signs point to an empty womb or illness, not a surviving child. His compassion contrasts with the agreeable certainty offered by the court physician.
An Unborn Child Lost

Reality Replaces Consolation
No delivery comes
Katherine’s body returns to its usual cycle, revealing that the promised surviving twin never existed. The court’s confidence cannot make the pregnancy real.
A private reckoning
She resents the medical ignorance around her and recognizes Yusuf’s honesty. The loss creates an opening for doubt about the knowledge her upbringing condemned.
A Second Secret Visit

Knowledge Sought Again
A renewed need
Katherine secretly asks Yusuf for advice about conceiving and carrying another child. She still fears that consulting him contradicts her mother’s teaching.
Practical counsel
He recommends exercise before conception, rest at the right time, boiled water, and fresh food. His advice treats her as a person with a body, not merely a royal vessel.
A Changed Judgment

From Enemy to Human Being
Compassion remembered
Katherine recalls Yusuf’s honesty and care when she faces grief and medical uncertainty. His conduct becomes harder to dismiss as the behavior of an enemy.
A broader conclusion
She questions the expulsion of scholars and the equation of learning with heresy. The encounter contributes to her rejection of persecution as a path to Christian virtue.
