Reappraisal of the etymology of tendo Achillis: Achilles, the aggressor or the sufferer?

This study critically reassesses the etymology of the tendo Achillis, examining its connection to Achilles as depicted in classic epics. It challenges the interpretation by Joseph Hyrtl, first presented in the 19th century and still widely accepted, which credits Philippus Verheyen with the introduction of Achilles-related terminology in the late 17th century. Through an extensive review of anatomical publications from the 16th to the early 18th century across Western Europe, categorized into four distinct periods, this study investigates the origins of the nomenclature for the distal tendon of the triceps surae (DTTS = tendo calcaneus), including both the terminology and the narrative contexts beyond its anatomical functions. The findings reveal that names associated with Achilles predate Verheyen, contradicting Hyrtl's timeline, and suggesting a more intricate association with the figure of Achilles. This not only illuminates the development of one of the most recognized anatomical eponyms but also enhances our understanding of the interplay between medical terminology and cultural narratives.
