This article presents a study of rock art from the Chalinga valley in Chile focusing on a set of motifs similar to the famous masks of the Limari style. Moving from the suggestive concept of "mask" to that of "framed figures", we consider the rock art motifs as compositional spaces within which elements are combined according to specific rules of design. These combinations are studied both statistically and in terms of symmetry in order to propose a design sequence, which in conjunction with other independent archaeological data allow us to discuss the development of Chalinga's rock art vis-a-vis the Limari style and its relation with the populations from Early Ceramic and Diaguita Periods present in this area.
