Final answer:
The Doric style of column is characterized by a simple capital and no base, where the column shaft rests directly on the temple's stylobate.
Step-by-step explanation:
The style of column that has a simple capital and no base is the Doric style. The Doric order is one of the three classical orders of ancient Greek architecture and is distinguished by its plain, unadorned column capital and the absence of a base. The column shafts of Doric columns rest directly on the stylobate of the temple and are typically fluted with twenty parallel grooves. Additionally, the Doric entablature includes a frieze composed of triglyphs and metopes. This architectural order is known for its sturdy, sometimes stocky proportions and features like the simple square abacus and a flared echinus on its capitals.
