Asklepios (latin: Asclepius), the god of healing, was an important deity to our medicus Gaius Petreius Ruso (Medicus: A Novel of the Roman Empire, by Ruth Downie). A statue of the god was kept at the entrance of the base hospital, and Ruso paid his respect daily.
An excellent discourse can be found on Asklepois at theoi.com.
