Quirinus is the deified Romulus, the founder of Rome. He was served by the Flamen Quirinalis, one of the three major flamines who served the oldest gods of Rome. His festival, the Quirinalis, was celebrated February 17.
Connections to Other Gods
Quirinus was originally a Sabine god of storms and thunder. He was assimilated into the state cult of Rome when Rome annexed the Quirinal, a fortified settlement for whom Quirinus was the eponymous. Under Greek influence, he lost his original attributes to Iuppiter, but continued, with Iuppiter and Mars, to form the triad of sky gods. By the time of the late Republic, he had become the deified form of Romulus. Prominent in early Rome, he faded into obscurity in later times.
Quirinus was depicted as a bearded man, wearing a combination of military and clerical clothing.
