jurisdiction of the Praefectus Urbi extended as far as the east coast and for in every direction. This might suggest that his subordinate, the Praefectus Vigilum, had a commensurate responsibility.) In popular culture The Vigiles often play a prominent role in the Marcus Didius Falco novels of Lindsey Davis, providing assistance in Falco's investigations. In particular, Falco's old army friend Lucius Petronius Longus is a 'Watch Captain' in Regio XIII. In Death in Vesunna by Harry Turtledove, the vigiles of Vesunna, Roman Gaul (now modern Périgueux, France) are tasked to hunt down two murderers from the future, whose victim was a prominent citizen in the city whom they murdered with a pistol. Despite initial bafflement, the head of the vigiles is able to solve the case with help from his Greek doctor friend and arrest the murderers despite their previously unknown weapon.
