Parking is in concentric semicircles, mirroring the small park just east of the station. Hills are shown by overlapping semicircles, rivers by lines, and cities by circles. Lines, semicircles, grids, insects, flowers, leaves, trees and squares were favourite motifs. Islands are represented as a rectangle, which has semicircles on the right and left side. Form an arbelos with the two inner semicircles tangent at point "C". They can be combined in single or multiple rows, or in semicircles or circles. These two semicircles form the funnel-shaped branchial crown. There are several ways to divide the meridian into semicircles. The salinon (meaning "salt-cellar" in Greek) is a geometrical figure that consists of four semicircles. Fabric-D contained designs of slanted lines or semicircles in some, while most pots were plain. The basic framework of the city consists of two large semicircles about in diameter. A salinon is the figure bounded by these four semicircles. Most structures today referred to as "sheepfolds" are ancient dry stone semicircles. The vault, composed of semicircles, was done by the Florentine Antonio de' Pucci.
