A genio lumen. En siddende kvinde skriver, til højre for denne gyder en anden kvinde olie på en lampe 1743 - 1809

"A genio lumen" is a pen and ink drawing created by Danish artist Nicolai Abildgaard between 1743 and 1809, currently held at the SMK - Statens Museum for Kunst. The artwork features two figures - one seated, meticulously working on a piece of fabric, and the other standing, pouring oil into a lamp. The drawing's title, meaning "A Genius for Light", highlights the theme of inspiration and knowledge illuminated by art, represented by the figures and the act of oiling the lamp. This intimate scene demonstrates Abildgaard's mastery of linework, creating a sense of movement and depth through the figures' drapery and the surrounding foliage. The drawing is a testament to the enduring themes of artistic inspiration and creative process found in Abildgaard's work.
