From evident observing points within the adjacent buildings to the west and east, they formed an artificial toothed horizon that spanned\u2014almost exactly\u2014the annual rising and setting arcs of the Sun. The Chankillo towers thus provide evidence of early solar horizon observations and of the existence of sophisticated Sun cults, preceding the Sun pillars of Incaic Cusco by almost two millennia.<\/jats:p>","DOI":"10.1126\/science.1136415","type":"journal-article","created":{"date-parts":[[2007,3,2]],"date-time":"2007-03-02T10:46:06Z","timestamp":1172832366000},"page":"1239-1243","source":"Crossref","is-referenced-by-count":55,"title":["Chankillo: A 2300-Year-Old Solar Observatory in Coastal Peru"],"prefix":"10.1126","volume":"315","author":[{"given":"Ivan","family":"Ghezzi","sequence":"first","affiliation":[{"name":"Instituto Nacional de Cultura, Avenida Javier Prado Este 2465, Lima 41, Peru."},{"name":"Pontificia Universidad Catolica del Peru, Avenida Universitaria Cuadra 18, Lima 32, Peru."},{"name":"Yale University, 51 Hillhouse Avenue, New Haven, CT 06511, USA."},{"name":"School of Archaeology and Ancient History, University of Leicester, Leicester LE1 7RH, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clive","family":"Ruggles","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Cultura, Avenida Javier Prado Este 2465, Lima 41, Peru."},{"name":"Pontificia Universidad Catolica del Peru, Avenida Universitaria Cuadra 18, Lima 32, Peru."},{"name":"Yale University, 51 Hillhouse Avenue, New Haven, CT 06511, USA."},{"name":"School of Archaeology and Ancient History, University of Leicester, Leicester LE1 7RH, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"221","reference":[{"key":"e_1_3_1_2_2","first-page":"11","year":"2005","unstructured":"C.
