This religious painting is divided into three distinct horizontal zones. In the foreground, six figures wearing richly colored robes and golden halos are engaged in conversation, arranged in a linear group against a dark landscape. The middle section depicts a magnificent walled medieval city with numerous spires and towers stretching across the width of the painting, dominated by a central cathedral with a prominent spire. The upper portion shows a dramatic celestial scene with three figures mounted on white horses emerging from billowing clouds. Above them, a brilliant golden sunburst with radiating orange-red rays illuminates the heavens. The overall color palette combines deep reds and blues with golden tones, creating a mystical atmosphere that aligns with the "ethereal" quality suggested by the title. The composition draws the eye upward from the earthly gathering through the celestial city to the divine light above.
