El Greco had one son, George Manuel, who was appointed architect of the Cathedral. He also practised sculpture and painting, in the latter medium imitating his father’s style so closely that some of the son’s pictures have been attributed to him. The portrait of a beautiful girl, late the property of Sir John Stirling-Maxwell and now in the National Gallery, London, has been called the artist’s daughter; but later criticism assigns this painting either to Tintoretto or to El Greco’s early Italian period when he was still a young man. The portrait of his son George, is identified in the _San Martin_ of San José, and again as the youth who holds the map in the _Vista of Toledo_. It is also supposed to exist in the younger figure of the boy on the left of the composition of _The Funeral of Count Orgaz_. In the latter it has also been suggested that the face with the pointed beard, sixth from the right, represents El Greco himself; while tradition also attributes the title of _Self Portrait of the Artist_ to the picture in the Seville Museum of a man of middle age, holding a brush and palette. These, however, are only surmises. The mystery that surrounds the life of El Greco is perhaps a little lifted by the account of him which Guiseppe Martinez gives in his “Practical Letters on the Art of Painting.” It is not the evidence of a contemporary, but of one who probably got his impressions from those who had known the artist or at least the opinion commonly held of him during his life. “At that time there came from Italy a painter called Dominico Greco; it is said that he was a pupil of Titian. He settled in the famous and ancient city of Toledo, introducing such an extravagant style that to this day nothing has been seen to equal it; attempting to discuss it would cause confusion in the soundest minds; his works being so dissimilar that they do not seem to be by the same hand. He came to this city with a high reputation, so much so that he gave it to be understood that there was nothing superior to his works. In truth he achieved some works which are worthy of estimation and which can be put among those of famous painters. His nature was extravagant like his painting. It is not known with certainty what he did with his works, as he used to say no price was high enough for them, and so he gave them in pledge to their owners who willingly advanced him what he asked for. He earned many ducats, but spent them in too great pomp and display in his house, to the extent of keeping paid musicians to entertain him at meal times. His works were many, but the only wealth he left were two hundred unfinished paintings; he reached an advanced age, always enjoying great fame. He was a famous architect and very eloquent in his speeches. He had few disciples, as none cared to follow his capricious and extravagant style, which was only suitable for himself.”
