For over four centuries, the deaths of two members of Renaissance Florence's most powerful dynasty were shadowed by whispers of poison and fratricidal ambition — a narrative that fit the era's reputation for ruthless intrigue. Now, genetic analysis of their preserved remains has quietly closed the case: malaria, not murder, ended their lives. The discovery is a humbling reminder that history's most dramatic stories are sometimes undone not by rival scholars, but by a mosquito and a strand of ancient DNA.
