A solitary figure emerges from a deep black background, his face illuminated by a dramatic, almost supernatural light that falls from the left. The man is elderly, with a full grey beard and hair, his features sharply modelled by the strong contrast of light and shadow. He wears a voluminous robe, the outer layer a rich golden ochre and the inner garment a cool, shimmering blue, both rendered in sweeping, expressive brushstrokes.

His right hand supports a large, open book, while his left delicately turns a page, the fingers elongated and almost spectral against the dark void. The book’s thick pages catch the light, their creamy tones standing out against the shadowed folds of his robe. The figure’s gaze is cast downward, absorbed in the text before him, his expression contemplative and grave.

The composition is tightly focused, with the figure filling most of the canvas, his form emerging from darkness as if conjured by the light itself. The brushwork is loose and energetic, especially in the handling of the drapery, where swift strokes suggest both weight and movement. The absence of any background detail or setting heightens the sense of spiritual introspection, concentrating all attention on the figure and his book. This is Apostle Saint Simon, painted by El Greco between 1610 and 1614.

El Greco’s characteristic style is evident in the elongated proportions of the hands and the expressive modelling of the face. The painting’s intense contrasts and vibrant colours are hallmarks of his late period, as seen in the glowing blue and gold of the apostle’s robes.
