Young Curly Brunette Girl With A Beaded Necklace Shows Off On The Terrace Surrounded With White Columns

Columns, or at least large structural exterior ones, became much less significant in the architecture of the Middle Ages, and the classical forms were abandoned in both Byzantine architecture and the Romanesque and Gothic architecture or Europe in favour of more flexible forms, with capitals often using various types of foliage decoration, and in the West scenes with figures carved in relief. Renaissance architecture was keen to revive the classical vocabulary and styles, and the informed use and variation of the classical orders remained fundamental to the training of architects throughout Baroque, Rococo and Neo-classical architecture.
Structure
Early columns were constructed of stone, some out of a single piece of stone. Single-piece columns are among the heaviest stones used in architecture. Other stone columns are created out of multiple sections of stone, mortared or dry-fit together. In many classical sites, sectioned columns were carved with a centre hole or depression so that they could be pegged together, using stone or metal pins. The design of most classical columns incorporates entasis (the inclusion of a slight outward curve in the sides) plus a reduction in diameter along the height of the column, so that the top is as little as 83% of the bottom diameter. This reduction mimics the parallax effects which the eye expects to see and tends to make columns look taller and straighter than they are while entasis adds to that effect.
