Another Saint Emeterius is associated with the legend of Saint Severus of Barcelona.

Saints Emeterius (Hemeterius) and Celedonius (; ; died 300 AD) are venerated as saints by the Catholic Church. Two Roman legionaries (and possibly also brothers), they were martyred for their faith around 300. They are patron saints of Calahorra (La Rioja), which is traditionally regarded as the place of their death.
