- Star Tales - Triangulum Australe (ianridpath.com)
One of the 12 constellations introduced at the end of the 16th century by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman, and the smallest of them according to modern boundaries. A southern triangle had previously been shown in a completely different position, south of Argo Navis, on a globe of 1589 by the Dutchman Petrus Plancius, along with a southern cross, but they were not the constellations we know today. The modern Triangulum Australe was first depicted in 1598 on a globe by Petrus Plancius and first appeared in print in 1603 on the Uranometria atlas of Johann Bayer.
- Marcel Duchamp (Wikipedia)
Henri-Robert-Marcel Duchamp (UK: /ˈdjuːʃɒ̃/, US: /djuːˈʃɒ̃, djuːˈʃɑːmp/, French: [maʁsɛl dyʃɑ̃]; 28 July 1887 – 2 October 1968) was a French painter, sculptor, chess player, and writer whose work is associated with Cubism, Dada, and conceptual art. He is commonly regarded, along with Pablo Picasso and Henri Matisse, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting and sculpture. He has had an immense impact on 20th- and 21st-century art, and a seminal influence on the development of conceptual art. By the time of World War I, he had rejected the work of many of his fellow artists (such as Henri Matisse) as “retinal”, intended only to please the eye. Instead, he wanted to use art to serve the mind.
