Answer:
Poussin combines nature and geometric architectural elements in Landscape with Saint John on Patmos, to let the viewer know this is a fictional or idealized landscape roman
Explanation:
Nicolas Poussin was a great French artist and a great influence on classicism. His works were extremely poetic and expressive that appealed to the emotion of those who saw his works, however he constantly put elements that influenced reason and mathematical rigor. He wanted his works to express a purity and an adequate sentimentality with the presence of rational, academic and often philosophical factors.
An example of this is the constant portrayal of nature aligned with geographic elements in its landscapes. Poussin combines nature and geometric architectural elements in Landscape with Saint John on Patmos, to let the viewer know this is a fictional or idealized landscape roman.
