Question: What is the currency of the group that built The Temples of Humankind ?

<P0-S0> Iconography of Shiva temples in Tamil Nadu is governed by the Shaiva Agamas (IAST:Āgama) that revere the ultimate reality as the Hindu deity, Shiva. <P0-S1>  Āgama (Sanskrit: आगम, Tamil:ஆகமம்) in the Hindu religious context means a traditional doctrine or system which commands faith. <P0-S2>  Temple worship according to Āgamic rules can be said to have started during the Pallava dynasty (551-901 A.D.) in South India, but they were fully under establishment during the Chola dynasty (848-1279 A.D.) The temples during the Chola period expanded to Sri Lanka and islands in South East Asia. <P0-S3>  The temple complex was expanding with niches for various deities on the stipulated sides of the sanctum. " <P0-S4> Lingam" was universalised and "prakarams" (precincts) with subsequent deities came up. <P0-S5>  The temple "parivara"(deities related to primary deity) expanded considerably during the Chola period. <P0-S6>  The niches of following Āgamic rules for building Shiva temples in Tamil Nadu, a South Indian state continues even in the modern era. <P0-S7>  Some of the prime images like that of "lingam", Vinayagar and Parvati are present in all the Shiva temples. <P0-S8>  Almost all the temples follow the same custom during festivals and worship methods with minor exceptions. <P0-S9>  Most of the Shiva temples in Tamil Nadu and Sri Lanka (like Munneswaram temple, Koneswaram temple, Tennavaram temple, Ketheeswaram temple, Naguleswaram) are built in Dravidian architecture. <SEP> <P1-S0> The Temples of Humankind are a collection of subterranean temples buried 100 ft underground built by the Federation of Damanhur. <P1-S1>  They are decorated in several motifs stressing peaceful human collaboration. <P1-S2>  The Temples are located in the foothills of the Alps in northern Italy, 30 mi from Turin, in the valley of Valchiusella. <SEP> <P2-S0> The Federation of Damanhur, often called simply Damanhur, is a commune, ecovillage, and spiritual community situated in the Piedmont region of northern Italy about 30 miles (50 km) north of the city of Turin. <P2-S1>  It is located in the foothills of the Alps in the Chiusella Valley, bordering on the Gran Paradiso National Park. <P2-S2>  The community has its own constitution and currency, the "Credito". <SEP> <P3-S0> The Bhutanatha group of temples is a cluster of sandstone shrines dedicated to the deity Bhutanatha, in Badami town of Karnataka state, India. <P3-S1>  There are two major temples here. <P3-S2>  Temple No.1, on the east side of the lake, called the Bhutanatha temple has a superstructure that resembles early South Indian style or North Indian style with its open mantapa (hall or Veranda) extending into the lake, while the smaller Temple No.2 on the north-east side of the lake, sometimes called the Mallikarjuna group of temples, has a stepped superstructure, commonly found in Kalyani Chalukya constructions. <P3-S3>  The inner shrine and mantapa (hall) of Temple No.1 were constructed in the late 7th century, during the reign of the Badami Chalukyas. <P3-S4>  While the outer "mantapa", facing the Badami tank, was completed during the rule of the Kalyani Chalukyas of the 11th century. <P3-S5>  Hence the Bhutanatha temple contain architectural forms from different periods. <P3-S6>  Studies show that these Kalyani Chalukya architects could have belonged to the same early phase workshop, that later built the nearby Yellamma temple and the Mallikarjuna group of temples.
