Les XX



Para-Impressionism: Other exhibitions

Les XX

Independant group exhibitions in Brussels



Les XX were also called les Vingt (the twenty) and ‘cercle / groupe / association des XX’ (circle / group / association of the 20) (iR26). Les XX was founded 1883/10/28 by Octave Maus (1856-1919) and a group of founding artists. Shortly after they invited other artists and formed a groupe of 20 artists or Vingtistes↓. These artists were opposed to the clichés of official art, (sometimes) refused by the official juries and formed a groupe of avant-garde artists (R5,p214;R56,p110;R68,p100;R88II,p209;iR3). Other artists later joined this groupe of Vingtistas, like Redon, Signac and also Jan Toorop and Henry van de Velde (iR3). Les XX had no president or governing committee. Instead Octave Maus (a lawyer, art-critic and journalist) acted as the secretary. Théo van Rysselberghe had a large influence on Les XX and recruited artists (R68,p41+102). Les XX were recognized by the State as a semi-institutional structure being aloud to exhibit in musea (R68,p102). The partaking artists used various styles like Impressionism, Symbolism and Divisionism (R68,p104).

The exhibitions were held yearly from 1884-93 and held in February and March. Every year also foreign artists were invited, in 1888 16 and in 1889 17 (so not 20 every year as some sources claim (iR3;R3,p421). Among these invited artists there were also partakers of the ‘impressionist’ expositions. Denvir states that all Impressionists exhibited at these Salons except Caillebotte, but Caillebotte was part of the 1888 exhibition. (R5,p214;iR19;R102,p283). As far as I know Degas didn’t exhibit with Les XX (though he was invited in 1886+88+89 (R1,p554;R47;R26,p13), nor Rouart (R92), nor Boudin.

There were 32 till 40 participants. In 1884 they showed an average of 2,8 and in 1885 4,5 art-works. We see later on, that partakers exhibited more works, like Monet 10 paintings in 1886 and James Ensor 22 works in 1888. So in general there were more partakers than at the ‘impressionist’ expositions from 1874-86, but they showed much less works per person and probably a bit less art-works were shown per exhibition.

During the exhibitions there were also lectures and concerts held (R3,p421). In 1893 of les XX was abolished because of differences of opinion among them. The same year Octave Maux founded ‘la Libre Esthétique’ (R5,p214;R68,p41;R3,p421).


Who were the founding members? Which members continued to exhibit with Les XX? Which artists later became member?
Sources give various answers (R88II,p209;R68,40;iR3). The founding group existed at least of Frantz Charlet*, Paul Du Bois (Dubois)*, James Ensor*, Alfred William (Willy A.)  Finch* (1854-1930), Charles Goethals, Fernand Khnopff* (1858-1921), Darío de Regoyos*, Théo Van Rysselberghe* (1862-1926), Guillaume (-S) Van Strydonck* (1861-1937). Some include Rodolphe Wytsman (or Witsman; 1860-1927) (iR3); others Willy(-Herman) Schlobach* (1864-1951) (iR3;R68); others Guillaume Vogels* (1836-96) and Périclès Pantazis (R68;R88); others also Jean Delvin, Frans (Franz) Simons, Gustave (Guillaume) Vanaise and Theodoor Verstraete (R88).
7 of the founding members later stopped being a Vingtiste: Goethals (not in 1887 + 88 + 89 + 91) and Wytsman (only affirmed in 1885), Pantazis (probably stopped in 1885), Delvin, Simons, Vanaise and Verstraete (probably in 1887). Other artists were invited to become a member, namely Achille Chainaye, Jef Lambeaux, Piet Verhaert. At last there were 20 members or Vingtistes. All these invited members stopped being a Vingtistes, some probably in 1885: Lambeaux, Verhaert; others probably in 1889: Chainaye. So, only 10 members stayed a Vingtiste from 1884-1893 (above indicated with an *). Note: Walther also mentions Isidore Verheyden (1846-1905) as one of the co-founders, but this is not affirmed by other sources (R3,p420).

Other artists later became a Vingtistes. Some (probably) 1885 onwards: Guillaume Charlier, Jan Toorop (1858-1928) (R298,p229). Others probably 1887 onwards: Félicien Rops. Others probably 1888 or 1889 onwards: Auguste Rodin. In 1888 the following artists also were members: Mlle A. Boch, Henry De Groux (see catalogue). Others probably 1890 onwards: George Minne (R298,p134;iR3). Others probably 1891 onwards: Robert Picard, Paul Signac. (iR3;iR1;R88II,p210/1;R116I,p202+213+225;iR19/R236).

Some sources claim Anna Boch was a member from 1885-93 (iR3), but in 1885 she was not in the catalogue (iR1); it is affirmed that she was a Vingtistes in 1887 + 88 + 89 + 91 (R116I,p202+213+225;iR19/R236;iR3;R3,p420). Some sources mention that Isidore Verheyden was member from 1884-88 (iR1), but he was absent in the 1884 catalogue (iR1), it is affirmed that he was a Vingtistes in 1887 (R116I,p202), but not in 1888 +89 + 91 (iR19/R236;R116I,p213+225;iR3). Some sources claim that Georges Lemmen (1865-1916) was a member starting 1888 (iR3), but this is not affirmed by the catalogue (iR19/R236); it is confirmed he was a member in 1889 + 91 (R116I,p213+225;R3,p421). Some sources claim that Henry van de Velde (1863-1957) was a member starting 1888 (iR3), but this is not affirmed by the catalogue (iR19/R236); it is affirmed that he was a member in 1889 + 91. Henry De Groux (Henri Degroux) at least was a member from 1887-89, but not in 1891. Some claim Odilon Redon later became a member (iR3), but this is not confirmed by other sources (R116I,p202+213+225;iR19/236).

The sources are inconsistent on where the exhibitions of Les XX were held in Brussels. Some sources state that the exhibitions of 1884+85+86 were held in the Palais des Beaux-Arts (R88II,p209;iR3), which opened in 1880 (iR3). This is affirmed by the catalogues of 1884+85 (iR1). Another source (wrongly) mentions these exhibitions were held in the Musée ancien des Beaux-Arts (R68,p102) and another source that it was held in 1887 in the Ancien Musée royal de peinture (R116I,p202). Some sources state that the other exhibitions (1887-93) were held at La Musée Moderne (R88II,p209;R68,p102;iR3;R306,p139). But another source calls it differently: in 1889 Ancien Musée de peinture and in 1891
Musée de Peinture (R116I,p213+225).

In the Salon database I could find the catalogues of the first exhibition in 1884 (iR1) and the second in 1885 (iR1). On archive.org I could find the catalogue of the 5th exhibition in 1888 (iR19/R236). I couldn’t find other catalogues, anyway not on gallica (iR40).
