What characteristic defines the Tuscan order in architecture?

The Tuscan order in architecture is characterized by its simplified capitals. This order is part of the Doric order but presents a more restrained and less ornate design. The capital of a Tuscan column is typically smooth and unadorned, distinguishing it from other orders that feature more elaborate capitals, such as the Corinthian or Composite orders. This simplicity is representative of the Tuscan style's overall aesthetic, which emphasizes solidity and clarity.

In the context of classical architecture, the Tuscan order embodies a sense of strength and practicality, as seen in its sturdy columns and overall proportions. The absence of fluting on the columns further emphasizes the simplicity of this order, reinforcing its characteristic features. Understanding these design principles helps in recognizing the Tuscan order as a vital element of classical architecture that influenced later architectural movements.
