Four-fold rotational symmetry in art: example n.2
<p>The Halaf culture is a prehistoric period which lasted between about 6100 BC and 5100 BC. The period is the ontinuous evolution of the earlier Pottery Neolithic. Its location is mainly in the fertile valley of the Khabur River (Euphrates), although Halaf-influenced material is found throughout Greater Mesopotamia, The image shows Halafian wave with a four-fold symmetric decoration. The image is an elaboration of .courtesy image:by:Yuber, 28/05/2005, for Wikimedia.org.</p>
Four-fold rotational symmetry in art: example n.3
<p>The Samarra culture is a Late Neolithic culture of northern Mesopotamia. The figure shows a bowl (ca. 4000 BC) on exhibit at the Vorderasiatisches Museum, Berlin. The figure has been obtained from a picture taken by Dbachmann, a courtesy for Wikimedia.org - commons.wikimedia.org/wiki/File:Samarra_bowl.jpg. The given description tells that the bowl was found by Ernst Herzfeld in the 1911-1914 campaign. It is also told that the design shows four fish being caught by four birds. This is the four-fold symmetry here mentioned.in the tile. The dscription given in Wikimedia is also stressing that "as is typical of cultures from this region, the use of a base six numerical system can be seen in the lines surrounding the bowl, so that there are a total of 120 lines, or four quarters with 30 lines each".</p>
