Abstract Hand representations are scarce in the rock art from northern Baja California. They have been identified at only five archaeological sites located in the territory that was inhabited by Kumeyaay groups during the late prehistoric period. The analyzed hand designs are associated with geometric elements, mainly concentric circles, diamonds, zigzags, triangles, and schematic anthropomorphic designs with or without fingers and toes; these elements are characteristic of the graphic style known as La Rumorosa. The designs can be classified into two categories, drawn hands and positive imprints. Some of the latter may be decorated or stylized. In all cases, the designs are monochromatic and were made with red, white, or black pigments. The lack of uniformity in the representation, style, colors, and placement of the designs on the panels seems to indicate that hand impression was not a common practice and that the analyzed cases are related to special events in the ritual activity that involved a diverse population.

来自墨西哥北下加利福尼亚州的岩画手工设计

摘要 在北下加利福尼亚州的岩画中，手部描绘很少见。仅在史前晚期 Kumeyaay 群体居住的领土内的五个考古遗址中发现了它们。分析的手部设计与几何元素相关，主要是同心圆、菱形、锯齿形、三角形以及有或没有手指和脚趾的示意拟人设计；这些元素是被称为 La Rumorosa 的图形风格的特征。设计可以分为两类，手绘和正面印记。后者中的一些可能被装饰或风格化。在所有情况下，设计都是单色的，由红色、白色或黑色颜料制成。表现形式、风格、颜色缺乏统一性，
