Maria Clara Eimmart began systematic lunar-phase drawings by 1693, laying foundations for selenography.
By the year 1693, Maria Clara Eimmart commenced a project of systematic lunar-phase drawings using her father's telescopes at the Nuremberg observatory. This undertaking was significant as it provided a rich visual record of the moon's phases through systematic observation, pioneering a method that was integral long before photography. These drawings are a testament to her observational skills and her ability to integrate art with scientific accuracy.
