Azae Ḥawāse Khamsa Ẓāhira—the five external sensory organs—is the cornerstone of the historical development of medical and philosophical thought. This study offers a novel historical-comparative analysis. It elucidates the specific methodological differences between Greek philosophical reasoning and Arabic empiricism, and demonstrates how this shift drove concrete anatomical advancements through detailed historical tracing. Through the works of Aristotle, Hippocrates, and Galen, Greek tradition established the epistemological framework of the five senses, primarily within a philosophical context. However, these early interpretations often lack clinical and gross anatomical precision. During the Islamic Golden Age (8th–13th centuries Common Era [CE]), Arabic medicine rose as scholars like Hunayn ibn Isḥāq, Al-Rāzī, and Ibn Sīnā critically engaged with Greek texts, translating, revising, and expanding their scope. By integrating clinical observations and empirical methods, Greco-Arabic medicine significantly advanced the concept of Azae Ḥawāse Khamsa Ẓāhira, laying crucial groundwork that demonstrably foreshadowed developments in modern neuroanatomy and ophthalmology. Crucially, these findings underscore the enduring diagnostic and therapeutic principles that are directly traceable to Greco-Arabic refinements. This provides concrete evidence of their active role in shaping modern Unani medical curricula, thereby offering a more nuanced understanding of how Unani medicine has historically continued.
