Luminous Projections and The Teaching of Cosmography
imaginary, Ideal and Mechanical Figures at The CNBA
Keywords:
glass plates, photography, luminous projections, high school education, astronomyAbstract
The article analyzes some glass plates used in the cosmography classes at the Colegio Nacional de Buenos Aires between 1912 and 1949. These plates reproduced drawings, paintings, and photographs related to astronomy that circulated in important scientific institutions of the time. Some plates, labeled imaginary, depicted objects inaccessible to direct observation, such as the interior of the Sun or the craters of the Moon. Others, offering photographs of the lunar landscape, were consigned as ideal. The article historically explores the use of imagination in the creation of these astronomical images, highlighting the combination of observation with disciplined imagination, and emphasizing the complementarity between photographic practices and the artistic techniques of drawing and painting.Downloads
