"Porphyria" as a Byzantine Phenomenon: Medicine, Dynasty, and Sacred Power Introduction: A Genetic Mystery in "Purple Swaddling Clothes" "Porphyria" (Greek: porphyra) — a precious purple dye extracted from rare mollusks and serving as an exclusive attribute of imperial power in Byzantium. Being born "in porphyria" (Porphyrogennetos) meant being born in a special chamber of the Constantinople palace, lined with purple porphyry, which emphasized the legitimacy and divine election of the heir. The phenomenon of "porphyria disease" is usually considered from the perspective of the instability of imperial power in Byzantium. Power was not always passed down by inheritance, especially in the early period of the state's existence. Unexpected individuals ascended to the throne: Justin I, his nephew Justinian, Empress Theodora, and others. In this case, "porphyria disease" refers to not a political metaphor, but a hypothetical genetic disorder, presumably affecting Byzantine dynasties, linking a physical ailment with the sacred status of the ruler. This phenomenon lies at the intersection of medical history, dynastic politics, and cultural anthropology. 1. The Hypothesis of Porphyria: A Medical Retrospective In the 1960s, British psychiatrist and biochemist Idris McAlpine put forward a sensational hypothesis that the famous British king George III, suffering from fits of madness, was afflicted with acute intermittent porphyria — a rare genetic disorder disrupting the synthesis of hemoglobin. Later, he and other researchers suggested that similar symptoms could have plagued Byzantine emperors as well. Porphyria is a group of diseases in which porphyrins, toxic precursors of hemoglobin, accumulate in the body. The acute intermittent form (AIP) can cause: Severe abdominal pain not related to food poisoning. Nervous and psychiatric disorders: hallucinations, anxiety, aggression, paranoia (interpreted as "madness"). Sun sensitivity (in some forms), leading to skin erosion. Reddis ... Read more
