Spanish school; XVII century."San Lucas".Oil on canvas. Relined.Measurements: 79 x 60 cm; 100 x 84,5 cm (frame).Devotional image that presents St. Luke the Evangelist inscribed in a border. The saint is seated with his gospel open before the spectator, and leaning on his knees. In one of his hands he holds a pen, while with the other he grasps the book. His gaze is directed directly towards the viewer, thus establishing contact with him, in an attitude of certain complicity. The scene ends with the presence of the bull, of which only its head is visible. Hidden behind the figure of the saint, the animal located in the left zone of the composition, also directs his sight towards the front. It is the presence of the bull, which defines the iconography of the evangelist, although it is worth mentioning that it is common the representation of the saint dressed in green tunic and red mantle, as can be seen in this work, and arranged with his pen and his gospel. As for the aesthetic representation, it follows the parameters of the Spanish baroque, using earthy and dark tones, on which a focus of light is directed.Saint Luke the Evangelist is considered by Christian tradition to be the author of the Gospel that bears his name, and also of the Acts of the Apostles. He was Paul's beloved physician, although not an apostle of Jesus, of probable Syrian origin, possibly converted to the Christian faith when the followers of Jesus, persecuted in Jerusalem and Caesarea, sought refuge outside Palestine, carrying with them the message of Christ. To him is also attributed the first portrait of the Virgin, so he is considered the patron saint of painters.
