Oil paint has been applied to many different supports, of which the most popular and enduring have been wooden panels and stretched canvas. Panels have tended to become uncommon in recent centuries because of their weight and cost, but in the nineteenth century reappeared in novel form among those sketching in front of the motif, who took to using wood from cigar boxes.

Smoking cigars became popular during that century, particularly among the better-off living in cities. Made from chopped tobacco wrapped in a tobacco leaf, cigars are delicate and affected by humidity, so are sold in small wooden boxes often made from cedar wood. Their lids, particularly those of about 13 by 26 cm (5 x 10 inches) size, were repurposed as the support for many oil sketches. When reading their description, if they’re given as oil on panel with similar dimensions, you should suspect that they may well have been painted on a cigar-box.

The earliest artists who are known to have painted on cigar-boxes are the Italian painters known as the Macchiaioli, a breakaway movement centred on Tuscany in northern Italy from about 1850, that in many ways anticipated Impressionism.

Odoardo Borrani joined the Macchiaioli in 1855, and in about 1865 painted this Peasant Child at Castiglioncello on a wooden panel of 23.3 x 14.7 cm that had almost certainly originated in a cigar box. The unusual linear cracks seen here are characteristic of the thin cedar wood popular in cigar boxes, when used without an adequate ground.

Giovanni Fattori’s plein air paintings are characteristic of the Macchiaioli: using small panoramic wood panels, he painted in macchia (taches or patches), in a style not dissimilar to that of the Barbizon School in France. This panel showing The Rotonda at Palmieri (1866) is slightly wider at 12 x 35 cm.

Fattori’s Portrait of Silvestro Lega, Painting Beside the Sea from 1866-67 is on another panel of 12.5 x 28 cm. This also shows the underlying grain, and its lack of any substantial ground. The artist shown appears to be painting in a pochade box onto another panel that may well be a cigar box.

Later in the century others followed, among them James Abbott McNeill Whistler.

In the 1880s, Whistler painted small outdoor views on panels, such as Harmony in Blue and Pearl: The Sands, Dieppe from about 1885. Although its dimensions are slightly different at 14 x 22.9 cm, this is almost certainly on a cigar box. The vertical streaks seen here are probably the result of a thin ground underneath the surface paint layer.

The greatest European exponent of painting on these small wooden panels was Georges Seurat, who mostly used them for studies made in preparation for his larger paintings. When Seurat started work on his monumental painting Les Poseuses (Posers, or Models) in 1886, he made a series of figure studies that are now in the Musée d’Orsay.

Each was painted using Seurat’s Divisionist technique on the wooden lid of a cigar box of about 24 by 15 cm size, which the artist termed a croqueton, his favourite support for such sketches.

In the late 1880s, several artists started painting in the rural area of Heidelberg, east of Melbourne, adopting a style that later became known as Australian Impressionism. They came together in a momentous exhibition in the history of Australian art, the 9 by 5 Impression Exhibition, in Melbourne, in 1889, named from the dimensions in inches of the standard Australian cigar-box lid of 13 by 23 cm.

Its principal artists were Charles Conder, Tom Roberts, and Arthur Streeton, many of whose rough-worked and colourful plein air sketches were painted on cigar boxes.

Roberts’ Going Home from about 1889 has dimensions of 23.4 x 13.6 cm. Linear marks in the lower section appear to be the result of the grain in the wood.

His oil sketch of Hutt Valley from 1900 is slightly smaller at 10.3 x 19.1 cm.

Conder’s view of the Dandenongs from Heidelberg from about 1889 uses a more standard size of 11.5 x 23.5 cm.

His Ricketts Point, Beaumaris (1890) is 12 x 21.5 cm with rounded corners.

In the twentieth century, many smokers switched to cigarettes sold in cardboard packets, and the supply of cigar-boxes dried up.

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.
