Outside of the Baths of Diocletian is a row of steles of Roman soldiers from different eras and corps. They typify the simple, rectangular headstones honoring those who died in service. Among the collection are members of Nero’s Imperial German Bodyguards (Germani Corporis Custodes). These foreigners were charged with protecting emperors starting in 30 BC. They were disbanded upon the death of Emperor Nero in 68 AD.
