Context: Circe ( ; (Greek: Κίρκη "Kírkē" ] ) is a goddess of magic or sometimes a nymph, witch, enchantress or sorceress in Greek mythology.  By most accounts, she was the daughter of the sun god Helios, and Perse, an Oceanid nymph.  Her brothers were Aeetes, keeper of the Golden Fleece, and Perses.

The Nova Iguaçu Volcano ("Vulcão de Nova Iguaçu" in Portuguese) is located in the state of Rio de Janeiro, Brazil, in an area of volcanic rocks at the north-eastern border of the Mendanha massif.  Klein and Vieira proposed the site to be an extinct volcano with a volcanic cone, volcanic crater, and volcanic bomb.  Scientific journals have studied the volcanic geology of the area, identifying the rocks of volcanic appearance as constituted of subvolcanic intrusive rock bodies.  The Nova Iguaçu volcano theory is now extinct in academic communities, but the myth continues in sightseeing promotion groups. Lost Land of the Volcano is a three-part nature documentary series produced by the BBC Natural History Unit which follows a scientific expedition to the island of New Guinea.  The expedition team, which includes specialist zoologists, explorers and the BBC crew, travels to the extinct volcano of Mount Bosavi in central Papua New Guinea to document the biodiversity of this little-visited area and search for new species.  At the time of filming, logging was taking place about 20 mi south from the volcano, and one of expedition's aims was to find evidence to support the case to protect the area.  Some members of the expedition team travelled to the island of New Britain several hundred kilometres to the east to chart an unexplored cave system and observe an active volcano. Achada Grande Tras (meaning the rear portion of Achada Grande, former spelling: Achada Grande Trás) is a volcanic plateau and a subdivision in the east of Praia in the island of Santiago, Cape Verde and forming the easternmost neighborhood.  It is the largest neighborhood in Praia being about 25 km2 , 6 km long, and 4 km wide.  The highest point is about 120 meters at the extinct volcano, the elevation at the center is about 55 meters, the lowest point is the Atlantic and the Praia Harbor.  Other elevations are 67 meters at Monte Faxo, 110 meters at the extinct volcano, 80 to 100 meters at the airport, about 70 meters at Adega and 105 meters at the northwesternmost portion near the Circular Road (EN1-ST06). Volcán Maderas, a long extinct volcano, stands at 1,394 meters and the trails wind you through an established cloud forest, and it is still by no means an easy feat.  Expect around a 6 – 8 hour round trip to the top of this prehistoric volcano.  Pack a lunch, and bring at least 2 liters of water per person.  If you want to swim in the lagoon inside the crater add another hour hiking plus whatever time you spend there.  A Guide is required and should cost around $10 per person, but they will want a minimum of $20.  There are also trails around the forest level that wrap completely around the volcano.  There are petroglyph tours, coffee and cacao tours, horseback riding, and the San Ramón waterfall is also located on the western side. Ometepe Island Map Mater Matuta was an indigenous Latin goddess, whom the Romans eventually made equivalent to the dawn goddess Aurora, and the Greek goddess Eos.  Her cult is attested several places in Latium; her most famous temple was located at Satricum.  In Rome she had a temple on the north side of the Forum Boarium, allegedly built by Servius Tullius, destroyed in 506 B.C., and rebuilt by Marcus Furius Camillus in 396 B.C., and she was also associated with the sea harbors and ports, where there were other temples to her. Mount Gahinga, is a dormant/extinct volcano in the Virunga Mountains on the border between Rwanda and Uganda.  Gahinga lies between Muhabura and Sabyinyo, but is the smallest of these three.  Mount Gahinga, also known in the local Kinyarwanda/Rufumbira dialect as "a small pile of stones", has a swampy caldera on its peak.  The caldera is believed to be about 180 meters wide.  Mgahinga Gorilla National Park also got its name from this volcano.  Mount Gahinga, whose elevation is 3,474 meters, is part of a chain of 8 volcanic mountains of the Mufumbiro ranges.  The volcano chain spans across Uganda, Rwanda and the Democratic Republic of Congo. Kerkis or Kerketeus (Greek, Modern: Κέρκης, "Kérkis"; Ancient: Κερκετεύς, "Kerketeús") is an extinct volcano, forming the bulk of the center of the Greek island of Samos.
