In more or less plausible relationship with the pintaderas cited in the first part of this post, ethnohistorical sources mention the use of badges or emblems among Gran Canaria indigenes. Let us quote some relevant texts.
From Antonio Sedeño‘s account:MORALES (1978, pp. 367, 369). Translated from old Castilian by PROYECTO TARHA.
[…] they brought bucklers taller as a man, made of rough light wood from a tree called dragon. The sword they called Majido and the shield tarja; swords were thin and pointed; they brought their badges painted their way in white and ochre red over the bucklers, played the sword with great skill.
