Gaffurio’s 1518 woodcut depicts a planetary ladder ascending through nine celestial rungs that mirrors Pythagorean superparticular ratios for cosmic consonance. Tied to church modes and alchemical metals, the ladder symbolizes ascent from terrestrial chaos to stellar perfection, with Muses as planetary avatars conducting the sphere's silent symphony. This visual splendor integrates music theory, astrology, and hermetic philosophy, portraying the universe as a resonant scala naturae.
