The Horse/Bitriangular style comprises mostly paintings and some petroglyphs. It features the bitriangular geometric representation of human figures in flat color and records the first domesticated horses’ appearance. Humans are represented as engaged in different activities. Pastoral, domestic, and convivial scenes – often represented in an oasis – alternate with depictions of hunting, scenes with flying galloping chariots or fights with humans wielding spears or lances. These artworks are mainly located on the walls of rock shelters. They are widespread over the whole massif, with significant clusterings along the central and southern wadis, especially along the course of the Wadi Senaddar. The represented scenes reflect the final phases of the Pastoral period and the early Garamantian culture, approximately dating between the middle of the third and the first millennium BCE.
