Frantisek Kupka is a colorist, like Kandinsky or Mondrian. Living in Paris since 1896, he is passionate about the relationships between colors in post-impressionist painting. He will seek to express momentum, rotation, vibration. The bright blue, which always seeks to dominate, will have to be circumscribed.
For Kupka, synthetic cubism is not a lasting solution because it remains focused on the object. In 1910-1911, his masterpiece, showing his wife's head buried amidst vertical structures, redefined the relationship between the figurative and its environment, as Klimt was doing in Vienna.
The figurative aspects then disappear from his work, but he still likes to draw inspiration from Gothic cathedrals to express the strength of verticals.
Le Jaillissement is a suite of three opuses painted in 1922-1923. The artist gives the preeminence to the verticals rather than to the confrontations between verticals and horizontals.
Jaillissement I is a tight network of stacked shapes. The similarity to a skyscraper seen from below is however obvious. In the second opus, the artist reinforces this illusion by adding a horizon line and removing the colored spots in the foreground. Jaillissement II, oil on canvas 126 x 86 cm, was sold by Sotheby's on March 25, 2021 for £ 7.6M including premium from a lower estimate of £ 1.5M, lot 146.
