"The Shrinking Heart": The Pathologies of Sadness in Medieval and Early Modern Culture

From the time of Classical Greek medicine through Early Modernity, sadness was considered both a mood and a diagnosable disease. Sadness was closely related to the physiological condition of melancholia, as both sadness and melancholia stemmed from a common etiology (excess of black bile), and both conditions could result in death. Sadness and melancholia had a symbiotic relationship; either one of the two could trigger the other. Because sadness was melancholia's foremost symptom and catalyst, medieval physicians often referred to melancholia and sadness as interchangeable notions and sometimes as synonyms. Influenced by Hippocratic-Galenic systems of thought that dominated the discipline of medicine well after the Renaissance, premodern doctors and natural philosophers conceived the idea that excessive sorrow greatly harmed the human body. They believed that sadness was more than a mood. This paper probes the physiological dimensions of sadness, arguing that from ancient Greek medicine to the Early Modern period, some physicians and natural philosophers believed that because of its inherent relationship with the caustic and cold substance of black bile, sadness had the power to physically shrink the heart. To support my argument, I analyze the medical traditions that developed from the Hippocratic-Galenic system of humorism, zeroing in on the humor of black bile as the main agent of corrosion and contraction. Because the shrinking-heart theory transcended the discipline of medicine, I also investigate this principle in the disciplines of theology, philosophy, and amatory literature in order to demonstrate the impact that the theory of the shrinking heart had on the European imaginary from the Middle Ages to Early Modernity.
