Fac-similé d’une ancienne composition représentant les constellations du ciel septentrional – after Andreas Cellarius – c.1900 Beautiful early 20th-century offset lithograph reproducing one of the celestial maps from Andreas Cellarius’s Harmonia Macrocosmica (1660), showing the constellations of the northern sky (ciel septentrional). The richly coloured plate depicts the mythological figures and zodiac signs of the northern celestial hemisphere — including Orion, Persée, Hercule, Lion, and Vierge — surrounded by decorative clouds and cherubs. It is accompanied by its original thin translucent tissue overlay, printed in blue ink, which identifies the constellations, zodiac signs, and principal stars (La voûte étoilée septentrionale, d’après une ancienne composition). This overlay serves as a guide to the intricate imagery beneath — an uncommon feature that enhances both its educational and decorative value. Issued as a supplement to the encyclopedic publication L’Univers et l’Humanité, printed by Maison d’Édition Bong & Cie, Paris, around 1900.
