Astrologers Calculating a Genethlialogy

Two men wearing early 17th-century doublets and caps sit at a table inside an indoor space, which opens onto a landscape through two large stone pillars. The man on the left points his finger toward the night sky, while the man on the right, also gesturing, looks toward the celestial globe resting on the table. The room features a tile floor, a bookshelf, and a separate side table with an open manuscript. Through the open archway, a landscape is visible featuring a rising sun on one side and a starry sky with a large sun or moon on the other.

This image is an illustration from Robert Fludd's 'Utriusque Cosmi Maioris scilicet et Minoris metaphysica, physica atque technica historia' (1617–1621), a foundational text for 17th-century Hermeticism and Neoplatonic natural philosophy. It illustrates the 'Genethlialogia' or the science of calculating horoscopes to determine the influence of celestial bodies on the soul and human life.
