Bartolomé Esteban Murillo (1617–1682) could be considered the most important Spanish painter in the 17th century.  He depicted women and children of his time and major religious works mostly between 1670 to 1682. He was extremely popular and he influenced artists such as Thomas Gainsborough which was his admirer.

Ground layers and imprimitura

An extensive technical examination

[1] of a collection of 6 Murillo’s paintings revealed that the calcite based ground is covered with a lead white based imprimatura. As for the coloration of the ground “Invitation to a Game of Angolla” [2] has a reddish brown ground which allow the figures to stand out while “Three boys” [2] has a lighter greyish ground which donates greater luminosity to the composition and it is associated with a later period of the artist.

Pigments Checker is a collection of 54 swatches of his­tor­i­cal pig­ments that have been applied using gum ara­bic as a binder on a cel­lu­lose and cot­ton water­color paper, acids and lignin free. This paper is not treated with opti­cal bright­en­ers, it’s slightly UV flu­o­res­cent, and it reflects IR. Two cross-hair lines, 0,2 mm (ver­ti­cal) and 0.4 mm (hor­i­zon­tal) are printed on each swatch of paper before the appli­ca­tion of paint, in order to have a means to eval­u­ate the pig­ments’ trans­parency in the IR and IRR imag­ing. Among all the pig­ments and their vari­eties ever used in art these pig­ments col­lec­tion select the most used ones from antiquity to early 1950’.


Pigments

The study [1] on the  collection of 6 paintings showed lead white, vermilion, red ochre, red lake, ultramarine, smalt, lead tin yellow type I, massicot, ivory black, lamp black and malachite.

Red

Murillo used vermilion (HgS) which is used in two forms, mineral (cinnabar) and synthetic (vermilion). It seem that Murillo used the natural mineral (cinnabar) because the pigments particles are thick and heterogeneous in sizes and irregular in shape. It must be noted that Almaden in Spain has the largest historical cinnabar mines and the town is close to Seville where the workshop of Murillo was located. Murillo made extensive use of red lakes for glazing over red paint or to add warmth such as to the clouds of the “Three boys” [2].

Blue

Murillo used expensive ultramarine sparingly and much more frequently he painted with the cheaper smalt. In “Invitation to a Game of Angolla” [2] and “Three boys” [2] the sky was probably much more blue but smalt degrades into a grey color over time. Ultramarine was used to over smalt to add intensity such as in “Virgin of the Rosary” [2].

Yellow

Murillo used lead tin yellow type I and massicot [1]. The first pigment has high hiding power and it was used in European paintings until 1750. On the other hand, massicot is less stable and was used less.

Green

Murillo obtained green hue mixing yellow and blue and only sparingly he used a green pigment (probably malachite [1]).

Painting Techniques

The X-ray examination of the “Invitation to a Game of Angolla” [2] showed that Murillo made no changes to the composition. This suggests a clear vision for the final result that he probably prepared on drawings.   On the other hand,  the X-ray of “Three boys” [2] clearly shows a change in the head’s position of one of the boys. This is not common for Murillo which is thought to be a careful planner for his compositions.

Copies

On the “Invitation to a Game of Angolla” pinpricks  were found along the sides of the canvas [2]. They were probably made to square-up and copy the painting as happened to many of Murillo’s masterworks.
