Aegidius is a Medieval Latin given name, the original form of Giles. It derives from the Late Latin name Aegidius, which in turn comes from Greek aigidion meaning "young goat." The name entered the vernacular via Saint Giles (Saint Egidio in Italian, Gilles in French), an 8th-century miracle worker from Greece who eventually settled in southern France. He became the patron saint of the crippled, and his cult contributed to the name's widespread use in medieval Europe. Etymology and Historical Usage In Old French, the Latin Aegidius evolved into Gidie and then Gilles. The form Giles was later imported to England through Norman influence. Other medieval Latin bearers include Giles of Rome (c. 1243–1316), a noted philosopher and theologian. The name remained popular among ecclesiastical and scholarly figures, appearing in contexts from hagiography to political history with the Roman general Aegidius. Notable Figure – Aegidius the General The most historically significant bearer from the given brief is Aegidius (died 464/465), a Roman magister militum per Gallias who governed the short-lived Kingdom of Soissons after the murder of Emperor Majorian by the general Ricimer. Aegidius refused to recognize the usurper Emperor Libius Severus and maintained independent rule in northern Gaul. He campaigned successfully against the Visigoths and Burgundians. There has been debate over whether he formally recognized Eastern Roman Emperor Leo I instead. Aegidius considered invading Italy but never did — possibly due to external pressure from the Aquitanian Goths or to safeguard Gaul's defenses. His kingdom would later pass to his son Syagrius. Despite the historical importance of this namesake, in modern European naming, Aegidius has fallen into disuse, largely overshadowed by its descendant forms like Giles and Egidio.
