With the Spanish colonization of the Americas, Christian priests used the name "Supay" to refer to the Christian Devil. However, unlike Europeans in relation to the Christian Devil, "the indigenous people did not repudiate Supay but, being scared of him, they invoked him and begged him not to harm them".
Supay acquired a syncretic symbolism, becoming a main character of the diabladas of Bolivia (seen in the Carnaval de Oruro), Peru and other Andean countries. The name Supay is now roughly translated into diablo (Spanish for devil) in most Southern American countries. In some of them, for example the northern region of Argentina, the underworld where Supay rules, is called "Salamanca".
In some areas of Peru, the Quechua people continue the tradition of the Supay dance at Mamacha Candicha which roughly translates as "flame virgin" and is a festival with dancing lasting up to two weeks. However, the dance of the Supay may be performed for tourists on other occasions not necessarily related to Mamacha Candicha.
