Question: Which trademark symbol of Marquesan tattoos often serve to mark the boundaries of sacred or significant sites?

<P0-S0> The twelve sacred hills of Imerina are hills of historical significance to the Merina people of Madagascar. <P0-S1>  Located throughout Imerina, the central area of the highlands of Madagascar, the sites were often ancient capitals, the birthplaces of key public figures, or the tomb sites of esteemed political or spiritual leaders. <P0-S2>  The first set of sacred sites was designated by early 17th-century king Andrianjaka. <P0-S3>  The notion was re-sanctified under late 18th-century king Andrianampoinimerina, who replaced several of the earlier sites with new ones. <P0-S4>  More than 12 sites were thus designated as sacred over time, although the notion of twelve sacred hills was perpetuated because of the significance of the number 12 in Malagasy cosmology. <P0-S5>  Today, little concrete evidence of the former importance of many of these sites remains, but the significant archeological and cultural heritage of several of the sites has been preserved. <P0-S6>  The historic significance of the sites is best represented by the Rova of Antananarivo at Analamanga, the ancient fortified city at Alasora, the houses and tombs of the andriana (noble class) at Antsahadinta and the ancient fortifications and palaces at Ambohimanga, protected as a UNESCO World Heritage Site since 2001. <SEP> <P1-S0>  He found the first woman Marikoriko in a pond; she seduced him and he became the father of Hine-kau-ataata. <P1-S1> In Māori mythology, Tiki is the first man created by either Tūmatauenga or Tāne. <P1-S2>  By extension, a tiki is a large or small wooden or stone carving in humanoid form, although this is a somewhat archaic usage in the Māori language. <P1-S3>  Carvings similar to tikis and coming to represent deified ancestors are found in most Polynesian cultures. <P1-S4>  They often serve to mark the boundaries of sacred or significant sites. <SEP> <P2-S0> The Puna-Ka'u Historic District is an archaeological district located on the Puna-Ka'u coastline in Hawaii Volcanoes National Park. <P2-S1>  The district includes over 300 sites occupied by Polynesians from the 13th through 19th centuries. <P2-S2>  Eleven of the sites within the district are considered exceptionally significant to modern understanding of native Hawaiian culture and have been the focus of most archaeological research in the area. <P2-S3>  Five of these sites are villages, at Poupou-Kauka, Kailiili, Kamoamoa, Lae'apuki, Keahou Landing; these village sites provide insight into the agricultural and social practices of the Polynesians. <P2-S4>  The Puna-Ka'u coastal trail, another one of the significant sites, connected these villages and provided a link to communities in the mountains. <P2-S5>  The remaining sites include the Wahaulu Heiau temple, the Puuloa petroglyph site, a pulu factory, and two shelter sites used by fishermen and opihi pickers. <SEP> <P3-S0>  Marquesan tattoos can be recognized by 'trademark symbols', such as geckos, centipedes, Ti'i's, the Marquesan Cross (which is also commonly confused with other designs) and other geometric designs. <P3-S1> A Marquesan tattoo is a tattoo design originating from the Marquesas Islands of the South Pacific. <P3-S2>  Marquesan designs distinguish themselves through the use of symbols and consistent artistic renderings of lines, arches and circles, which are uniquely attributed and linked through history to the South Pacific Islands. <P3-S3>  Marquesan Tattoos are a part of the Polynesian Tattoo art. <P3-S4>  The Marquesan Cross is often incorporated into larger Polynesian Tattoo Designs as it symbolises the balance between the elements and harmony.
