What is the name of the highest heaven in Dante's Paradiso?

The Empyrean is the highest heaven in Dante’s Paradiso, the timeless realm where God, the angels, and the blessed ultimately reside. Unlike the lower heavens, it is not a physical planetary sphere revolving through space.

Dante’s journey passes through nine moving heavens associated with the Moon, Mercury, Venus, the Sun, Mars, Jupiter, Saturn, the Fixed Stars, and the Primum Mobile. The Empyrean lies beyond them all. It is described as pure light and divine love, outside ordinary measurements of time and place.

In the final cantos, Beatrice brings Dante into the Empyrean, where he sees the “celestial rose,” an immense vision of the blessed arranged around God. The apparent locations assigned to souls in the earlier heavens are symbolic accommodations for Dante’s understanding, not permanent divisions of Heaven.

A common mix-up is calling the Primum Mobile the highest heaven. It is the outermost of the nine physical heavens and turns the universe, but the Empyrean is the transcendent heaven beyond it.
