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>
Two-fold rotational symmetry in art: example n.1
<p>The image shows a two-fold rotational symmetry displayed by the decorations of two wood-covers of Tibetan books. The symmetry is rendered by two animals (peacocks and lions). The covers are exhibited at the Museo d'Arte Orientale di Torino. The use of two-fold symmetry in icons is very old ( see Amelia Carolina Sparavigna, The Symmetries of the Icons on Ancient Seals, International Journal of Sciences 08(2013):14-20 DOI: 10.18483/ijSci.231 )</p>
Three-fold rotational symmetry in art: example n.2
<p>The three-fold symmetry is broken. In the center of the bowl, we find a four-fold symmetry. This is a bowl from the Majiayao neolithic China. Museo d’Arte Orientale di Torino.</p>
Three-fold rotational symmetry in art: example n.1
<p>Three-fold rotational symmetry in the decoration of this bowl of egyptian faience. Note the eye of the fishes at the center of the bowl. It seems a Escher's creation, but it is coming from the ancient Egypt - First period of XVIII Dinasty (XV century BC). It is amazing that very old creations (pottery and seals) show symmetry in their decorations.</p>
Two-fold rotational symmetry in art: example n.2
<p>The image shows a two-fold rotational symmetry displayed by the decoration of a wood-cover of a Tibetan book. The symmetry is rendered by two human figures. The cover is exhibited at the Museo d'Arte Orientale di Torino. The use of two-fold symmetry in icons is very old ( see Amelia Carolina Sparavigna, The Symmetries of the Icons on Ancient Seals, International Journal of Sciences 08(2013):14-20 DOI: 10.18483/ijSci.231 )</p>
Two-fold rotational symmetry in art: example n.3
<p>Faience bowl blue-glazed decorated with lotus flowers and the face of the goddess Hathor, symbol of rebirth are the decoration. Faience. Provenance unknown. New Kingdom, dynasty XVIII-XX (1350-1070 B.C.). Egyptian Museum, Turin.</p>
Four-fold rotational symmetry in art: example n.1
<p>A TLV mirror is a type of bronze mirror, popular during the Han Dynasty in China. They are called TLV mirrors because of the presence of symbols resembling letters T, L, and V are engraved on them. They were produced from around the 2nd century BCE until the 2nd century CE.</p>
Three-fold rotational symmetry in art: example n.3
<p>Bronze mirror from Hunan, China. Warring States, IV Century BC. Note the three-fold rotational symmetry. It is broken: the three animals are two preys and a predator.</p>
Four-fold rotational symmetry in art: example n.4
<p>The image shows a bowl with pool, tilapia fishes and lotus buds, It is a faience coming from Egypt, mold-made faience, 1550-1300 BCE, Cincinnati Art Museum. The image on the left is a courtesy by Wmpearl for Wikimedia. On the right, the processed image (Retinex, generic erode filter, grey scale) to enhance the detail of the design. </p>
Five-fold rotational symmetry in art: example n.1
<p>Decorated bowl of baked clay. Predynastic Period of Ancient Egypt, Naqada I, 3900-3700 BC. </p>
