The etymology of Visayas is unknown. The word "Bisaya" was first documented in Spanish sources in reference only to the non-Ati inhabitants of the island of Panay and possibly parts of Negros. They were described by the Spanish as being "white people" with no tattoos. In contrast, the Spaniards called the inhabitants of other Visayan islands as the "Pintados" ("the painted ones") in reference to their practice of tattooing their entire bodies. It is unlikely that "Bisaya" was used as a collective endonym by the closely related native Visayans prior to the Spanish arrival.
