Final answer:
The Maison Carrée is characterized by Corinthian columns and a gable roof, incorporating detailed elements such as egg-and-dart trim and acanthus leaf motifs.
Step-by-step explanation:
The architectural elements that characterize the Maison Carrée in Nîmes, France, are Corinthian columns and a gable roof. The Maison Carrée is a prime example of Roman temple architecture, following the principles outlined by Vitruvius, which influenced Romanesque building styles and led to the development of the Gothic style. The Maison Carrée features a deep porch, a high podium, and a frontal orientation. A key detail of this temple's stylistic elements includes the use of the egg-and-dart trim above the architrave and acanthus leaf motif on the Corinthian capitals, as shown in photograph annotations of the structure.
