Quote by Guillaume Apollinaire
A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.
Summary
This quote suggests that a structure transitions from being merely sculptural to becoming architectural when its elements no longer need to be justified by nature. In other words, architecture goes beyond replicating or imitating aspects of the natural world and instead embraces concepts, designs, and materials that deviate from what occurs naturally. By moving away from direct references to nature and incorporating unique architectural elements, a structure obtains its distinct architectural identity. This could involve incorporating design principles, complex geometries, innovative materials, technological advancements, or other creative variations that go beyond the constraints of nature.
