The Infanta Doña Margarita de Austria c. 1660 Oil on canvasA woven cloth used as a support for painting. The best-quality canvas is made of linen; other materials used are cotton, hemp, and jute. It is now so familiar a material that the word 'canvas' has become almost a synonym for an oil painting, but it was not until around 1500 that it began to rival the wooden panel (which was more expensive and took longer to prepare) as the standard support for movable paintings (the transition came later in Northern Europe than in Italy). Canvas is not suitable for painting on until it has been coated with a ground, which isolates the fabric from the paint; otherwise it will absorb too much paint, only very rough effects will be obtainable, and parts of the fabric may be rotted by the pigments. It must also be made taut on a stretcher or by some other means., 212 x 147 cm Museo del Prado, Madrid
Velázquez began this painting in the year of his death, it was finished and partly transformed by his son-in-law, Juan Battista Martinez del Mazo.
