Almost all who paint in oils use conventional brushes, but there’s a significant minority who sometimes, or frequently, use different tools to apply and shape the paint layer. Of those, the most popular are palette knives, generally used to move and mix paint on the palette. Others have used the other end of the brush stick to incise, or their fingers.

Marie Bashkirtseff’s painting of a class in the Académie Julien in Paris in 1881 demonstrates how oil painting should be done by the textbook. The artist, shown in her self-portrait in the centre foreground, is using a long-bladed palette knife to prepare the paint on her palette. At her feet, on an old sheet of newspaper, are her brushes, all with handles of typical length, and the pupil behind her is using a maul stick to rest her right hand while painting with her brush.

Gustave Courbet applied his paint using a palette knife for some of his paintings. This has been identified from the facture in some of his paintings of caves that he made from about 1864, including The Grotto of Sarrazine near Nans-sous-Sainte-Anne above.

Another enthusiast for painting with a knife was Auguste Renoir.

In 1866, Renoir painted his friend Jules Le Coeur and his Dogs in the Forest of Fontainebleau. This is unusual among his works, as it was preceded by two studies, and all three were made using the palette knife rather than brushes. This makes it most likely to have been painted before Renoir abandoned the knife and returned to the brush, by the middle of May 1866.

Renoir returned to the technique in The Mosque, also known as Arab Festival, in 1881. Small strokes of bright colour and energetic work with the palette knife give it a strong feeling of movement, and it so impressed Claude Monet that he bought it from Durand-Ruel in 1900.

Anna Althea Hills’ Fall, Orange County Park (1916) is a classic and highly accomplished plein air painting that appears to have been made with extensive and deft use of the knife, particularly in the foreground.

Perhaps the most famous artist who is known to have painted with his fingers is Leonardo da Vinci.

This Annunciation, painted in oil and tempera on a poplar panel, is generally agreed to be one of the earliest of Leonardo’s own surviving paintings. When it was painted is in greater doubt, but a suggestion of around 1473-75 seems most appropriate. There are numerous pentimenti, particularly in the head of the Virgin. Its perspective projection is marked in scores in its ground and Leonardo used his spontaneous and characteristic technique of fingerpainting in some of its passages.

Finally, some painters are well-known for their use of brushes with exceptionally long handles. These enabled them to stand back, sometimes almost on the opposite side of their studio, get an overall view of their canvas, and paint from the same distance as a viewer.

Like all plein air painters, Paul César Helleu (1859–1927) shown in John Singer Sargent’s An Out-of-Doors Study from about 1889, is using brushes with handles of modest length. His canvas is fairly small, and he’s working close-in while clutching a brace of brushes in his left hand. Some designed for use when painting in front of the motif have even shorter handles, but when back in the studio Helleu would almost certainly have opted for longer.

Whistler was renowned for using brushes with handles over one metre (39 inches) long, and appears to have used them when painting Symphony in White No. 1: The White Girl in 1862 on a canvas just over two metres (78 inches) tall. He reworked it between 1867-72 to make it more ‘spiritual’ and reduce its original realism.

Early in his career, Joaquín Sorolla established his reputation of painting ‘voraciously’, often using brushes with extremely long handles and large canvases. Although Sewing the Sail from 1896 may look a spontaneous study of the effects of dappled light, Sorolla composed this carefully with the aid of at least two drawings and a sketch, and given its 2.2 metre (87 inches) height, he was almost certainly using brushes of similar length.

Dice have been thrown and rolled by people throughout recorded history. Early dice were often irregular, made of bone or stone and used primarily for gambling. Although they don’t appear to have played any significant role in mythology, their role in the events of the Crucifixion is well recorded in the New Testament Gospels.

Jacopo Tintoretto’s huge and magnificent Crucifixion from 1565 depicts the biblical account of guards gambling with dice, as seen in the detail below.

On the left of this detail, two men are gambling with dice in a small rock shelter suggestive of a tomb. To the right of them, a gravedigger has just started his work with a spade.

The Christian Church has generally taken a dim view of gambling, and shunned dice. Several artists have expressed this in paint, but none so forcefully as Hieronymus Bosch.

For Bosch and his patrons, gambling was definitely one of the cardinal sins. It appears in the garden of Hell in the right panel of his magnificent Garden of Earthly Delights from about 1495-1505. In this damning conclusion, figures are mutilated and tormented in a nightmare landscape dominated by non-human creatures and alarming objects, where gambling takes the foreground.

In the foreground, a huge blue bird, wearing a cauldron on its head and swallowing a whole human, presides over the scene. Two main groups of victims here are clustered around objects associated with gaming and gambling, and those for making music, then associated with the work of the devil, and immoral activities such as dancing. Playing cards are scattered on the ground beneath an overturned gaming table, and dice are balanced precariously on an index finger and on the head of a naked woman. From among that cluster of figures, a pair of dark blue non-human arms holds high a backgammon board with three dice.

Not all cultures have been as damning, though.

Albert Anker turns to classical times to put his spin on gambling games in his Knucklebone Players (1864). Three youths are here playing a game of greater skill, but still frequently the basis of gambling. The distinguished men in the background are hardly the sort to frequent a gambling den, surely?

Nevertheless, playing with dice continued as a cardinal sign of sin.

Alcohol, and that other vice tobacco, are cited in David Teniers the Younger’s The Dice Shooters (1630-50). In common with other paintings of card-playing and gambling in this period, it’s set in a dingy room in a rough tavern. Drawing on their clay pipes and with glasses of beer in hand, a group of men are completely absorbed in gambling large stacks of coins on the throw of their dice.

William Hogarth’s successor Thomas Rowlandson painted his Gaming Table in watercolour in 1801. Players here are putting their stakes on dice, which are about to be revealed by the man at the far right of the table, who seems to have been raking the money in.

Although Gustave Courbet’s portrait of the operatic singer Louis Gueymard (1822–1880) as Robert le Diable (1857) shows the last scene in Act 1 of Giacomo Meyerbeer’s opera Robert le Diable (1831), its message is clear. In this scene, Gueymard’s character Robert gambles away his entire estate on dice; in the opera this is marked by the aria L’or est une chimère: ‘gold is but an illusion’.

Dante Gabriel Rossetti is less convinced. In his watercolour of Hesterna Rosa from 1865, he shows a moment from the contemporary play Philip van Artevelde, written by Henry Taylor in 1834. Van Artevelde was a Flemish patriot who lived between about 1340-1382, and led the Ghent rebellion in 1381, only to be crushed to death in battle the following year. In Taylor’s play, van Artevelde has a relationship with a woman of lower class; in this scene, his lover has paused to reflect on her life while he plays dice with a friend. The painting’s title means yesterday’s rose, and draws on the theme of the fallen woman, so popular with Rossetti.

Murillo’s Young Boys Playing Dice of about 1675 adopts a different theme, of gambling among the poor and vulnerable. Two scruffy urchins from the streets of Seville are throwing dice for the small piles of change which are probably their entire fortunes. A third stands over them, chewing at a bread roll while his dog looks up longingly at the food.
