A set of Old English poems personify this entity as a Chaldean nobleman who exchanges riddles with Solomon. After descending a golden ladder on this object, a soul spins so fast that it glows brightly, then reveals itself to Dante as Peter Damian. After thirty years, this object returns to the ecliptic longitude it occupied at someone’s birth, accounting for quarter-life crises in horoscopic astrology. Johannes Kepler modeled this body as a sphere enclosing a set of (*) Platonic solids. (-5[1])Erwin (-5[1])Panofsky co-wrote a study of the association between melancholy and being born under (10[1])the sign of this (10[1])planet. (10[1])The Paradiso places this planet just before the Fixed Stars as the seventh level of heaven. For 10 points, name this farthest of the classical planets, (10[1])named after the Roman equivalent (10[1])of Cronus. ■END■ (10[1])
