Final answer:
The late Classical period in Greek art was a departure from the traditional Classical Greek style. It reflected a more human and individualized approach, introduced new poses, and saw refinements in architecture.
Step-by-step explanation:
The late Classical period in Greek art marked a break away from the traditional Classical Greek style in several ways. Firstly, the art of the Late Classical period reflected a more human and individualized approach, departing from the idealized and serene style of the High Classical period. Sculptures depicted not only actual humans but also heroes and deities in a more realistic and expressive manner.
Additionally, artists in the Late Classical period began to experiment with new poses, expanding the repertoire of Greek art. These sculptures were still influenced by the Classical characteristics of idealism and the Severe style, but they also introduced new elements and movements.
Lastly, the Late Classical period saw refinements in architecture. Columns became more slender, the Corinthian order made its debut, and architects began to explore the effects of acoustics in theater design. These architectural changes opened the doors to experimentation and laid the foundation for future Hellenistic architecture.
