were shown, which may have been due to intensified fighting due to distinguished hierarchies. A changing climate, due to decreased water and pasture, may have been indicated with these types of weapons. Animals Domesticated animals made up nearly 69% of the artwork depicted at Ennedi Plateau. However, the rock art had the greatest emphasis on domesticated cattle. In fact, at one site, Murdi, researchers graphed the frequency of humans and animals found among the rock art. Cattle consisted of over 50% of the total pictures, caprids around 10%, and dogs around 5%. The first rock picture ever discovered included the "Apollon Garamante," which showed two masked persons on the side of cattle. Cattle were perceived as having unique horns, especially among longhorn cattle which occupied a large population. For instance, some cattle were given lyre-shaped horns. Cattle were known to have a large financial, cultural, and environmental impact on the people of the Ennedi highlands. They were also given distinct coats to individualize these animals, and rock art at some sites, including the Chiguéou II site, includes cattle figures in extravagant geometric designs. Cattle were found all among the highlands, while other animals, such as horses, were not. Other types of domesticated animals found included sheep and dogs. During the Iron Age, people survived on a more nomadic lifestyle, choosing to display camels and specifically horses in their pictures. However, these animals were not individualized with different coats as the cows were. Also, while paintings of cattle portray the animals as static, horses are shown as galloping animals, creating an artistic quality to the art. Some more recent paintings included horses with chariots. Horses are believed to not be exhibited in the artwork as much as other animals, such as cattle, due to a lesser influence on the pastoralists. Camels were also portrayed, as having more movement than the other animals. Wild animals were also portrayed in the artwork for their religious and mythical meanings. Giraffes were the most common wild animals demonstrated, and they were most often expressed during hunter-gatherer times. Also, numerous rhinos were crafted alongside round-headed humans, unusual for the typical behavior of rhinos as they usually live as couples or loners. People Depictions of people are fairly common in Ennedi rock art, and among the human figures found, only 4% were engraved. There were numerous handprints from both men and women found among the rock art.
