the Unicode character sets of two languages. In the Chinese block it is U+534D 卍 (left-facing) and U+5350 for the swastika 卐 (right-facing); The latter has a mapping in the original Big5 character set, but the former does not (although it is in Big5+). In Unicode 5.2, two swastika symbols and two swastikas were added to the Tibetan block: swastika , , and swastikas , . Meaning European hypotheses of the swastika are often treated in conjunction with cross symbols in general, such as the sun cross of Bronze Age religion. Beyond its certain presence in the "proto-writing" symbol systems, such as the Vinča script, which appeared during the Neolithic. North pole According to René Guénon, the swastika represents the north pole, and the rotational movement around a centre or immutable axis (axis mundi), and only secondly it represents the Sun as a reflected function of the north pole. As such it is a symbol of life, of the vivifying role of the supreme principle of the universe, the absolute God, in relation to the cosmic order. It represents the activity (the Hellenic Logos, the Hindu Om, the Chinese Taiyi, "Great One") of the principle of the universe in the formation of the world. According to Guénon, the swastika in its polar value has the same meaning of the yin and yang symbol of the Chinese tradition, and of other traditional symbols of the working of the universe, including the letters Γ (gamma) and G, symbolising the Great Architect of the Universe of Masonic thought. According to the scholar Reza Assasi, the swastika represents the north ecliptic north pole centred in ζ Draconis, with the constellation Draco as one of its beams. He argues that this symbol was later attested as the four-horse chariot of Mithra in ancient Iranian culture. They believed the cosmos was pulled by four heavenly horses who revolved around a fixed centre in a clockwise direction. He suggests that this notion later flourished in Roman Mithraism, as the symbol appears in Mithraic iconography and astronomical representations. According to the Russian archaeologist Gennady Zdanovich, who studied some of the oldest examples of the symbol in Sintashta culture, the swastika symbolises the universe, representing the spinning constellations of the celestial north pole centred in α Ursae Minoris, specifically the Little and Big Dipper (or Chariots), or Ursa Minor and Ursa Major. Likewise, according to René Guénon the swastika
