Final answer:
Claude Monet's 'The Saint-Lazare Station' portrays the architecture of the Parisian train station, embodying Impressionist themes, especially the observation of light in modern life.
Step-by-step explanation:
The painting 'The Saint-Lazare Station' by Claude Monet focuses on the theme of architecture. Painted in 1877, the artwork represents Monet's interest in capturing the modern life of his time and the effects of light on the urban environment, which are key tenets of the Impressionism movement. The Saint-Lazare train station in Paris is the central subject, with the vast iron and glass structure housing the platforms and trains. Monet's work is characterized by his technique of painting en plein air, which allowed him to record the transient effects of light and atmosphere. The artwork is an example of the impressive series of works Monet created that observe the same scene at different times and conditions to capture the changing light and its effects on the subject.
