Saint Luke is a painting by an artist known as El Greco.

According to the gallery label provided by the Indianapolis Museum of Art: "During the last decade of his career, El Greco played a major role in popularizing a type of pictorial ensemble known as the apostolado, or "apostle Series."

A complete Apostolado normally comprises thirteen pictures, with twelve bust-length paintings of Apostles and one of Christ as Savior.

The church was badly damaged during the Spanish Civil War (1936–39) and the paintings were removed for safekeeping and eventually sold.".
