Monet painted this picture of the sun seen through mist at the harbour of Le Havre when he was staying there in the spring of 1872. A sketch quickly executed to catch the atmospheric moment, it was catalogued as Impression: soleil levant when exhibited in 1874 in the first exhibition of the group (as yet described simply as the Société Anonyme des Artistes-Peintres). The word `Impression' was not so unusual that it had never before been applied to works of art but the scoffing article by Louis Leroy in Le Charivari which coined the word Impressionnistes as a general description of the exhibitors added a new term to the critical vocabulary that was to become historic. It was first adopted by the artists themselves for their third group exhibition in 1877, though some disliked the label. It was dropped from two of the subsequent exhibitions as a result of disagreements but otherwise defied suppression.
Monet's Impression was not in itself a work that need be regarded as the essential criterion of Impressionism, vivid sketch though it is. There are many works before and after that represent the aims and achievements of the movement more fully. Yet it has a particular lustre and interest in providing the movement with its name.
Monet used an almost sketchy technique to convey the sense of changing light. He painted the sun as having almost exactly the same luminance as that of the sky, a condition which suggests high humidity and atmospheric attenuation of light. This detail relies on the use of complementary colours and variety of colour temperature, rather than changes in color intensity or contrast of values, to differentiate the sun from the surrounding sky.
