where in greece was this major shrine to demeter
Demeter Demeter of Mysia had a seven-day festival at PellenÃ© in Arcadia.[68] Pausanias passed the shrine to Demeter at Mysia on the road from Mycenae to Argos but all he could draw out to explain the archaic name was a myth of an eponymous Mysius who venerated Demeter.[citation needed]
Hagia Sophia Hagia Sophia (/ˈhɑːɡiə soʊˈfiːə/; from the Greek Αγία Σοφία, pronounced [aˈʝia soˈfia], "Holy Wisdom"; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Ayasofya) is the former Greek Orthodox Christian patriarchal cathedral, later an Ottoman imperial mosque and now a museum (Ayasofya Müzesi) in Istanbul, Turkey. Built in 537 AD at the beginning of the Middle Ages, it was famous in particular for its massive dome. It was the world's largest building and an engineering marvel of its time. It is considered the epitome of Byzantine architecture[1] and is said to have "changed the history of architecture".[2]
