The Sudden Death of Cardinal Decio Azzolino Junior (1623-1689), the Universal Heir of Queen Christina of Sweden: A Dropsy Case?

Cardinal Decio Azzolino Jr. (1623-1689), a leading figure at the Roman curia in the 17th century met in 1655 queen Christina of Sweden, arrived in Rome after her conversion to Roman Catholicism. The queen appointed the cardinal as her universal testamentary heir before her death on April 16th, 1689. Azzolino died of a sudden death shortly after, on June 8th. The article aims to question Azzolino's sudden death through the analysis of the cardinal's illnesses from which he was afflicted in the last decades of his life, examining the most likely causes of his demise. Various unpublished epistolary letters were analysed, according to the chronological order of production between 1660 and 1689. A philological approach coupled with clinical-medical hypothesis inferable by the examined sources. The cause of death is identified as an unexpected dropsy in some letters and the death certificate. The analysis of the letters allows the reconstruction of Azzolino' state of health and illnesses in the last two decades of life: bilious excesses, inflammations, podagra and gout, which appeared with the inflammation of the knee and walking difficulties, and, finally, asthenia, dyspnea and a probable stroke. The dropsy is a symptom underlying various possible pathologies. The cardinal's state of health had been precarious and already marked by various symptoms, which were progressively worsening over the last decades of his life. The hypothesis of a stroke is also plausible. His death was not sudden as the Roman curial environments lead us to believe.
