ΤΕΤΑΡΤΑΙΟΣ
The quartan fever, one of the most recognizable and persistent forms of malaria in antiquity, was a central subject of study in Hippocratic medicine. Its name, meaning "that which appears on the fourth day," highlights the cyclical nature of the disease and the efforts of ancient physicians to understand and classify pathological phenomena based on time. Its lexarithmos (1287) reflects the complexity of numerical and temporal cycles in ancient thought.
REPORT ERRORDefinition
The term τεταρταῖος (quartan, specifically referring to fever) was a medical designation in ancient Greece for a type of fever that recurred every fourth day, i.e., with two full days of remission between paroxysms. This periodicity was characteristic of a form of malaria, likely Plasmodium malariae, which was widespread in the Mediterranean region.
The word derives from the adjective «τέταρτος» (the fourth) and denotes the precise temporal recurrence of symptoms. In contrast to «διταῖος» (quotidian, daily) and «τριταῖος» (tertian, recurring every third day), quartan fever was often considered more persistent and difficult to treat, though less acute in some cases.
Systematic observation and classification of fevers based on their periodicity formed a cornerstone of Hippocratic medicine. Quartan fever is extensively mentioned in the works of Hippocrates and other ancient physicians, not only for diagnosis but also for prognosis and therapeutic approach, as understanding the disease cycle was crucial for implementing appropriate interventions.
