Erasistratus Discovering the Cause of Antiochus’ Disease is a 1774 painting by French Neoclassical artist Jacques-Louis David. This work is located in the Beaux-Arts de Paris in Paris, France.
The story of Erasistratus discovering the cause of Antiochus’ disease is a compelling tale from ancient medical history, highlighting the astuteness of the Greek physician Erasistratus. This narrative involves Antiochus I Soter, a Seleucid king, and his lovesick condition, which was diagnosed by Erasistratus through keen observation and understanding of human emotions.
Antiochus, the son of Seleucus I Nicator, was suffering from a mysterious illness that baffled his court physicians. His symptoms included severe physical weakness, rapid weight loss, and a general decline in health. Despite their best efforts, the physicians could not identify the cause of his ailment.
Erasistratus, a renowned physician of the Hellenistic period, was summoned to diagnose and treat Antiochus. He carefully observed the young prince and noted that his condition worsened significantly whenever his stepmother, Stratonice, entered the room. Erasistratus hypothesized that Antiochus’s disease was not physical but rather emotional.
To confirm his theory, Erasistratus monitored Antiochus’s pulse and other physiological responses in the presence of different individuals. He observed that Antiochus’s heart rate and physical symptoms spiked dramatically when Stratonice was near. Erasistratus then concluded that the young prince was suffering from lovesickness, a condition caused by his unrequited love for his stepmother, Stratonice.
Upon revealing his diagnosis to Seleucus, the king faced a moral dilemma. Moved by his son’s suffering, Seleucus decided to abdicate his wife, Stratonice, to Antiochus. This selfless act not only cured Antiochus but also strengthened the bond between father and son.
