weathering from sand blown by the wind. The earliest works often portray animals that have since died out in the region due to climate change, including elephants, rhinoceros, hippopotamus and giraffes. More recent art includes ostriches, antelopes, gazelles, baboons and sheep. Later works, dated less than 2000 years old, portray domesticated animals, such as oxen and camels. Other engravings portray warriors dressed in feathers or spiked ornaments and armed with bows, shields, assegai, or traditional knives. Still others portray celebrations and scenes from everyday life. The walls of a canyon near Bardaï have engravings that measure over in height, including that of the "man of Gonoa", Gonoa being the name of the enneri that runs through the valley. These primarily show hunting scenes. The Tibesti art is unique in the Sahara because of the absence of inscriptions, the relative lack of chariots, and the low representation of camels and horses until comparatively recently. Other works The Tibesti Mountains have inspired several contemporary works of art and literature. The volcanic spires of the Tibesti, along with a stylized sheep's head, were displayed on a 20 CFA franc postage stamp issued by Republic of Chad in 1962. In 1989, French painter and sculptor Jean Vérame used the natural surroundings of the Tibesti to create multidimensional land art works by painting rocks. The Tibesti range was featured in the 1958 short story "Le Mura di Anagoor" ("The Walls of Anagoor") by the Italian novelist Dino Buzzati. In the story, a local guide offers to show a traveler the walls of a great city that is absent from the maps. The city is exceedingly opulent, yet exists in total autarky and does not submit to local authority. The traveler waits many years, in vain, to enter the Tibesti city.
