Cielo de Salamanca (Sky Over Salamanca), Salamanca
Within the courtyard of the Minor Schools at the University of Salamanca, the Sky Over Salamanca is a stunning 15th‑century fresco originally painted by Fernando Gallego in the 1480s. It once adorned the vault of the old university library—now transformed into the Chapel of Saint Jerome—but most of the original structure collapsed during later alterations. Only one-third of the celestial ceiling survived, hidden behind a false ceiling until its rediscovery in 1901.
The surviving fragment—roughly 8.7 meters in diameter—is a richly detailed astrological diagram, painted on a quarter‑sphere vault. It portrays zodiac signs such as Leo, Virgo, Libra, Scorpio, and Sagittarius, alongside constellations like Hydra, Boötes, and Hercules. The Sun and Mercury are represented dramatically—one riding a chariot and the other atop an eagle‑drawn vehicle—reflecting the iconography of the Poeticon Astronomicon, referred in English as “The Poetical Astronomy”.
Far more than decorative art, the fresco is a remarkable artifact of medieval science and education. Influenced by the university's recently established chair of astrology, the fresco likely served as a planetarium for teaching astronomy and medicine—offering students a visual guide to the cosmos and astrological houses. Despite popular belief, it does not represent the actual sky above Salamanca on a specific date—constellations from both hemispheres are depicted together—underscoring its symbolic, not literal, purpose.
Today, visitors can view this preserved fragment in the University Museum housed within the Minor Schools. The fresco, carefully transferred to canvas in the early 1950s, stands as a quiet yet mesmerizing reminder of the Golden Age of intellectual and artistic endeavor in Salamanca.
