Cariocecus was the god of war in Lusitanian mythology. It is the equivalent of the Roman god Mars and Greek Ares.

The Lusitanians practiced human sacrifices and when a priest wounded a prisioner in the womb they made predictions just by the way the victim fells down and by their insides. They sacrified to him not just prisioners but also horses and goats. The Lusitanians cutted the right hand of the prisioners and consacrated it to Cariocecus.
