Medieval Islamic Views of the Cosmos: “Mediterranean Map” taken from “The Book of Curiosities of the Sciences and Marvels for the Eyes. The manuscript is a copy, probably made in Egypt in the late 12th or early 13th century, of an anonymous work compiled in Egypt during the first half of the 11th century. It is extraordinarily important for the history of science, especially for astronomy and cartography, and contains an unparalleled series of diagrams of the heavens and maps of the earth. No less importantly, both the illustrations and the text preserve material gathered from Muslim astronomers, historians, scholars, and travellers, of the 9th to 11th centuries, whose works are now either lost or preserved only in fragments.”

“The Cueva de las Manos, Río Pinturas, contains an exceptional assemblage of cave art, executed between 13,000 and 9,500 years ago. It takes its name (Cave of the Hands) from the stencilled outlines of human hands in the cave, but there are also many depictions of animals, such as guanacos (Lama guanicoe ), still commonly found in the region, as well as hunting scenes. The people responsible for the paintings may have been the ancestors of the historic hunter-gatherer communities of Patagonia found by European settlers in the 19th century.” (Unesco)
