Lyssa: Goddess, Drug, Illness and Shield in Hellenic Antiquity.

Abstract

The aim of this historical review is to present the beliefs of the ancient Greeks related to lyssa and how the mythology surrounding this disease was created. In Greek antiquity Lyssa was a secondary goddess, a personification of a zoonotic disease which could be transmitted after an animal bite. Also named hydrophobia, the illness lyssa presented with an acute loss of mental stability, offensive frenzy and madness, and fear of water in the patient, who was seen to be possessed by a daemon as a divine punishment. In the Trojan War, lyssa was seen as a drug to Greek warriors, to demonstrate unreal power during battle. Homer was the first to refer to the hound of Orion, who was the greatest ancient Greek hunter. The hound, named Sirius, as a carrier of lyssa, was used as a bio-weapon to inflict death among the Trojans. Soranus of Ephesus and Galen gave descriptions of the disease, and proposed a sponge soaked with various herbal drugs as a therapeutic measure. The Greco-Roman physician Caelius Aurelianus noted that ancient Greeks knew about lyssa, and was the first to suggest that this was a neuro-disease. Lyssa was a figure in Greek Tragedy, depicted as a young female with a dog-like crown, related to Erinyes and Maniae. CONCLUSION: Lyssa was noted as a disease in Hellenic literature more than 2500 years ago. It was used as a bio-weapon to inflict madness. This vignette reveals Lyssa within a historical framework for the reader to understand the disease's origins.
