Discipline: Ethnography
IIoco ethnography has preoccupied others before Dr. Jocano. The earliest references to aspects of Iloco ethnography may be attributed to the Spanish missionaries. As early as the second half of the sixteenth century, the Spanish chronicler-missionary, Fr. Juan Gonzalez de Mendoza, had written about certain Ilocano socio-religious practices, like what he called devil-worship, for instance.
