In what century did the French prefer a strictly rectilinear approach in their art?

The preference for a strictly rectilinear approach in French art is most accurately associated with the 17th century, particularly during the Baroque period. This era was characterized by the use of geometric forms, balance, and symmetry, as evidenced by the works of artists such as Nicolas Poussin, who emphasized clarity and order through the use of straight lines and rectilinear composition.

In the 17th century, French classical ideals flourished, focusing on idealized forms and controlled expression, which is indicative of a rectilinear style. This approach reflects the broader influence of the French Academy and the desire for a cohesive visual language that aligned with emerging Renaissance principles of proportion and perspective, also steering away from the more dynamic and organic forms seen in earlier periods.

The rectilinear style laid the groundwork for subsequent movements and held considerable sway over French art through the ages, influencing aesthetics well beyond the 17th century.
