What is the biggest feature of the Ionian Order?

Ionian columns were formed in the 6th century BC, and the earliest examples can be traced back to the end of the 7th century BC. Its biggest feature is that there are two large scroll decorations on the stigma, and its origin may be the deformation of snails or shellfish in the ocean. Because the scroll is spread to both sides, the width of the stigma exceeds two-thirds of the diameter of the column. Bidoli-style columns are also more slender and look slimmer. The height of the column is about 9 times of the bottom diameter, and the number of grooves in the column is also increased to 24 to 48. The drum-shaped bulge in the middle is not obvious, and it contracts almost proportionally from bottom to top. The height of gables is one-fifth of the height of columns, thus creating a beautiful, lightweight and gorgeous effect.
