Ionic order

"The Ionic order is one of the three canonic orders of classical architecture, the other two being the Doric and the Corinthian. There are two lesser orders: the Tuscan (a plainer Doric), and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Ionic order has the narrowest columns.

The Ionic capital is characterized by the use of volutes. The Ionic columns normally stand on a base which separates the shaft of the column from the stylobate or platform while the cap is usually enriched with egg-and-dart.

The ancient architect and architectural historian Vitruvius associates the Ionic with feminine proportions (the Doric representing the masculine)." - (en.wikipedia.org 04.12.2021)
