A figure clad in a voluminous blue robe dominates the left side, arms raised in an ecstatic gesture toward the swirling sky. Clustered to the right, a group of elongated, nude figures stand or kneel against draped yellow and green cloths, their bodies contorted in gestures of supplication or awe. Some raise their arms heavenward, while others shield their faces or look toward the blue-robed figure, their pale forms stark against the dark ground and vibrant fabrics.

The background churns with energetic brushwork, clouds rendered in streaks of grey, white, and ochre, creating a sense of turbulence and divine intervention. The light falls unevenly, illuminating the blue robe and the pale bodies, while shadows deepen the folds of cloth and the hollows of limbs. The paint is applied in expressive, visible strokes, especially in the drapery and clouds, lending a sense of movement and urgency to the scene.

Details such as the angular fingers, the twisting torsos, and the almost metallic sheen of the blue robe reveal the artist’s distinctive style. A reddish cloth is spread across the lower center foreground, its folds painted with loose, sweeping strokes. The upper left corner is filled with dark, swirling clouds that merge into lighter streaks toward the center of the sky.

A single nude figure on the far right stands apart, arching backward with both arms raised high above the head. The green and yellow draperies behind the group of figures are painted with bold, jagged lines and abrupt shifts in color. The ground at the bottom is rendered in deep brown and black tones, with little detail, emphasizing the figures above.

Light catches the upraised faces and limbs, while the lower bodies and background remain partially obscured in shadow. The Vision of Saint John was created by El Greco around 1608–14 and is associated with the Mannerism movement. The Metropolitan Museum notes that the scene is unfinished and shows signs of damage and abrasion. The Metropolitan Museum acquired the painting in 1956, where it remains on display.
