as pétroglyphe.

In scholarly texts, a petroglyph is a rock engraving, whereas a petrograph (or pictograph) is a rock painting. In common usage, the words are sometimes used interchangeably.

Petroglyphs and petrographs both belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by many large rocks and boulders over the ground, are quite different. Inuksuk
