The epithet Ambulios was an ancient Greek religious invocation, specifically a designation of the Dioscuri in ancient Sparta. As Pausanias writes in his work “Description of Greece,” within the city of Sparta there were altars of the Ambulii Dioscuri in honor of these twin brothers near the temple of the god Apollo. It is very likely that this invocation was attributed to the abilities that the ancient Lacedaemonians ascribed to the Dioscuri to shorten or extend the lives of people. On the other hand, the word “ambulia” meant “delay in execution,” and, although it referred to the execution of a death sentence, it implied the prolongation of life and the postponement of death. With the same invocation, Zeus and the goddess Athena were also worshipped in Lacedaemon and elsewhere, as Ambulios Zeus and Ambulia Athena, respectively.
